CONFIGURATION FILE
------------------

The Git configuration file contains a number of variables that affect
the Git commands' behavior. The `.git/config` file in each repository
is used to store the configuration for that repository, and
`$HOME/.gitconfig` is used to store a per-user configuration as
fallback values for the `.git/config` file. The file `/etc/gitconfig`
can be used to store a system-wide default configuration.

The configuration variables are used by both the Git plumbing
and the porcelains. The variables are divided into sections, wherein
the fully qualified variable name of the variable itself is the last
dot-separated segment and the section name is everything before the last
dot. The variable names are case-insensitive, allow only alphanumeric
characters and `-`, and must start with an alphabetic character.  Some
variables may appear multiple times.

Syntax
~~~~~~

The syntax is fairly flexible and permissive; whitespaces are mostly
ignored.  The '#' and ';' characters begin comments to the end of line,
blank lines are ignored.

The file consists of sections and variables.  A section begins with
the name of the section in square brackets and continues until the next
section begins.  Section names are not case sensitive.  Only alphanumeric
characters, `-` and `.` are allowed in section names.  Each variable
must belong to some section, which means that there must be a section
header before the first setting of a variable.

Sections can be further divided into subsections.  To begin a subsection
put its name in double quotes, separated by space from the section name,
in the section header, like in the example below:

--------
        [section "subsection"]

--------

Subsection names are case sensitive and can contain any characters except
newline (doublequote `"` and backslash have to be escaped as `\"` and `\\`,
respectively).  Section headers cannot span multiple
lines.  Variables may belong directly to a section or to a given subsection.
You can have `[section]` if you have `[section "subsection"]`, but you
don't need to.

There is also a deprecated `[section.subsection]` syntax. With this
syntax, the subsection name is converted to lower-case and is also
compared case sensitively. These subsection names follow the same
restrictions as section names.

All the other lines (and the remainder of the line after the section
header) are recognized as setting variables, in the form
'name = value'.  If there is no equal sign on the line, the entire line
is taken as 'name' and the variable is recognized as boolean "true".
The variable names are case-insensitive, allow only alphanumeric characters
and `-`, and must start with an alphabetic character.  There can be more
than one value for a given variable; we say then that the variable is
multivalued.

Leading and trailing whitespace in a variable value is discarded.
Internal whitespace within a variable value is retained verbatim.

The values following the equals sign in variable assign are all either
a string, an integer, or a boolean.  Boolean values may be given as yes/no,
1/0, true/false or on/off.  Case is not significant in boolean values, when
converting value to the canonical form using '--bool' type specifier;
'git config' will ensure that the output is "true" or "false".

String values may be entirely or partially enclosed in double quotes.
You need to enclose variable values in double quotes if you want to
preserve leading or trailing whitespace, or if the variable value contains
comment characters (i.e. it contains '#' or ';').
Double quote `"` and backslash `\` characters in variable values must
be escaped: use `\"` for `"` and `\\` for `\`.

The following escape sequences (beside `\"` and `\\`) are recognized:
`\n` for newline character (NL), `\t` for horizontal tabulation (HT, TAB)
and `\b` for backspace (BS).  Other char escape sequences (including octal
escape sequences) are invalid.

Variable values ending in a `\` are continued on the next line in the
customary UNIX fashion.

Some variables may require a special value format.

Includes
~~~~~~~~

You can include one config file from another by setting the special
`include.path` variable to the name of the file to be included. The
included file is expanded immediately, as if its contents had been
found at the location of the include directive. If the value of the
`include.path` variable is a relative path, the path is considered to be
relative to the configuration file in which the include directive was
found. The value of `include.path` is subject to tilde expansion: `~/`
is expanded to the value of `$HOME`, and `~user/` to the specified
user's home directory. See below for examples.

Example
~~~~~~~

        # Core variables
        [core]
                ; Don't trust file modes
                filemode = false

        # Our diff algorithm
        [diff]
                external = /usr/local/bin/diff-wrapper
                renames = true

        [branch "devel"]
                remote = origin
                merge = refs/heads/devel

        # Proxy settings
        [core]
                gitProxy="ssh" for "kernel.org"
                gitProxy=default-proxy ; for the rest

        [include]
                path = /path/to/foo.inc ; include by absolute path
                path = foo ; expand "foo" relative to the current file
                path = ~/foo ; expand "foo" in your $HOME directory

Variables
~~~~~~~~~

Note that this list is non-comprehensive and not necessarily complete.
For command-specific variables, you will find a more detailed description
in the appropriate manual page.

Other git-related tools may and do use their own variables.  When
inventing new variables for use in your own tool, make sure their
names do not conflict with those that are used by Git itself and
other popular tools, and describe them in your documentation.


advice.*::
        These variables control various optional help messages designed to
        aid new users. All 'advice.*' variables default to 'true', and you
        can tell Git that you do not need help by setting these to 'false':
+
--
        pushUpdateRejected::
                Set this variable to 'false' if you want to disable
                'pushNonFFCurrent',
                'pushNonFFMatching', 'pushAlreadyExists',
                'pushFetchFirst', and 'pushNeedsForce'
                simultaneously.
        pushNonFFCurrent::
                Advice shown when linkgit:git-push[1] fails due to a
                non-fast-forward update to the current branch.
        pushNonFFMatching::
                Advice shown when you ran linkgit:git-push[1] and pushed
                'matching refs' explicitly (i.e. you used ':', or
                specified a refspec that isn't your current branch) and
                it resulted in a non-fast-forward error.
        pushAlreadyExists::
                Shown when linkgit:git-push[1] rejects an update that
                does not qualify for fast-forwarding (e.g., a tag.)
        pushFetchFirst::
                Shown when linkgit:git-push[1] rejects an update that
                tries to overwrite a remote ref that points at an
                object we do not have.
        pushNeedsForce::
                Shown when linkgit:git-push[1] rejects an update that
                tries to overwrite a remote ref that points at an
                object that is not a commit-ish, or make the remote
                ref point at an object that is not a commit-ish.

--

core.fileMode::
        Tells Git if the executable bit of files in the working tree
        is to be honored.
+
Some filesystems lose the executable bit when a file that is
marked as executable is checked out, or checks out an
non-executable file with executable bit on.
linkgit:git-clone[1] or linkgit:git-init[1] probe the filesystem
to see if it handles the executable bit correctly
and this variable is automatically set as necessary.
+
A repository, however, may be on a filesystem that handles
the filemode correctly, and this variable is set to 'true'
when created, but later may be made accessible from another
environment that loses the filemode (e.g. exporting ext4 via
CIFS mount, visiting a Cygwin created repository with
Git for Windows or Eclipse).
In such a case it may be necessary to set this variable to 'false'.
See linkgit:git-update-index[1].
+
The default is true (when core.filemode is not specified in the config file).

core.ignorecase::
        If true, this option enables various workarounds to enable
        Git to work better on filesystems that are not case sensitive,
        like FAT. For example, if a directory listing finds
        "makefile" when Git expects "Makefile", Git will assume
        it is really the same file, and continue to remember it as
        "Makefile".
+
The default is false, except linkgit:git-clone[1] or linkgit:git-init[1]
will probe and set core.ignorecase true if appropriate when the repository
is created.

core.precomposeunicode::
        This option is only used by Mac OS implementation of Git.
        When core.precomposeunicode=true, Git reverts the unicode decomposition
        of filenames done by Mac OS. This is useful when sharing a repository
        between Mac OS and Linux or Windows.
        (Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7).
        When false, file names are handled fully transparent by Git,
        which is backward compatible with older versions of Git.

core.protectHFS::
        If set to true, do not allow checkout of paths that would
        be considered equivalent to `.git` on an HFS+ filesystem.
        Defaults to `true` on Mac OS, and `false` elsewhere.

core.protectNTFS::
        If set to true, do not allow checkout of paths that would
        cause problems with the NTFS filesystem, e.g. conflict with
        8.3 "short" names.
        Defaults to `true` on Windows, and `false` elsewhere.

core.trustctime::
        If false, the ctime differences between the index and the
        working tree are ignored; useful when the inode change time
        is regularly modified by something outside Git (file system
        crawlers and some backup systems).
        See linkgit:git-update-index[1]. True by default.

core.checkstat::
        Determines which stat fields to match between the index
        and work tree. The user can set this to 'default' or
        'minimal'. Default (or explicitly 'default'), is to check
        all fields, including the sub-second part of mtime and ctime.

core.quotepath::
        The commands that output paths (e.g. 'ls-files',
        'diff'), when not given the `-z` option, will quote
        "unusual" characters in the pathname by enclosing the
        pathname in a double-quote pair and with backslashes the
        same way strings in C source code are quoted.  If this
        variable is set to false, the bytes higher than 0x80 are
        not quoted but output as verbatim.  Note that double
        quote, backslash and control characters are always
        quoted without `-z` regardless of the setting of this
        variable.

core.eol::
        Sets the line ending type to use in the working directory for
        files that have the `text` property set.  Alternatives are
        'lf', 'crlf' and 'native', which uses the platform's native
        line ending.  The default value is `native`.  See
        linkgit:gitattributes[5] for more information on end-of-line
        conversion.

core.safecrlf::
        If true, makes Git check if converting `CRLF` is reversible when
        end-of-line conversion is active.  Git will verify if a command
        modifies a file in the work tree either directly or indirectly.
        For example, committing a file followed by checking out the
        same file should yield the original file in the work tree.  If
        this is not the case for the current setting of
        `core.autocrlf`, Git will reject the file.  The variable can
        be set to "warn", in which case Git will only warn about an
        irreversible conversion but continue the operation.
+
CRLF conversion bears a slight chance of corrupting data.
When it is enabled, Git will convert CRLF to LF during commit and LF to
CRLF during checkout.  A file that contains a mixture of LF and
CRLF before the commit cannot be recreated by Git.  For text
files this is the right thing to do: it corrects line endings
such that we have only LF line endings in the repository.
But for binary files that are accidentally classified as text the
conversion can corrupt data.
+
If you recognize such corruption early you can easily fix it by
setting the conversion type explicitly in .gitattributes.  Right
after committing you still have the original file in your work
tree and this file is not yet corrupted.  You can explicitly tell
Git that this file is binary and Git will handle the file
appropriately.
+
Unfortunately, the desired effect of cleaning up text files with
mixed line endings and the undesired effect of corrupting binary
files cannot be distinguished.  In both cases CRLFs are removed
in an irreversible way.  For text files this is the right thing
to do because CRLFs are line endings, while for binary files
converting CRLFs corrupts data.
+
Note, this safety check does not mean that a checkout will generate a
file identical to the original file for a different setting of
`core.eol` and `core.autocrlf`, but only for the current one.  For
example, a text file with `LF` would be accepted with `core.eol=lf`
and could later be checked out with `core.eol=crlf`, in which case the
resulting file would contain `CRLF`, although the original file
contained `LF`.  However, in both work trees the line endings would be
consistent, that is either all `LF` or all `CRLF`, but never mixed.  A
file with mixed line endings would be reported by the `core.safecrlf`
mechanism.

core.autocrlf::
        Setting this variable to "true" is almost the same as setting
        the `text` attribute to "auto" on all files except that text
        files are not guaranteed to be normalized: files that contain
        `CRLF` in the repository will not be touched.  Use this
        setting if you want to have `CRLF` line endings in your
        working directory even though the repository does not have
        normalized line endings.  This variable can be set to 'input',
        in which case no output conversion is performed.

core.symlinks::
        If false, symbolic links are checked out as small plain files that
        contain the link text. linkgit:git-update-index[1] and
        linkgit:git-add[1] will not change the recorded type to regular
        file. Useful on filesystems like FAT that do not support
        symbolic links.
+
The default is true, except linkgit:git-clone[1] or linkgit:git-init[1]
will probe and set core.symlinks false if appropriate when the repository
is created.

core.gitProxy::
        A "proxy command" to execute (as 'command host port') instead
        of establishing direct connection to the remote server when
        using the Git protocol for fetching. If the variable value is
        in the "COMMAND for DOMAIN" format, the command is applied only
        on hostnames ending with the specified domain string. This variable
        may be set multiple times and is matched in the given order;
        the first match wins.
+
Can be overridden by the 'GIT_PROXY_COMMAND' environment variable
(which always applies universally, without the special "for"
handling).
+
The special string `none` can be used as the proxy command to
specify that no proxy be used for a given domain pattern.
This is useful for excluding servers inside a firewall from
proxy use, while defaulting to a common proxy for external domains.

core.ignoreStat::
        If true, Git will avoid using lstat() calls to detect if files have
        changed by setting the "assume-unchanged" bit for those tracked files
        which it has updated identically in both the index and working tree.
+
When files are modified outside of Git, the user will need to stage
the modified files explicitly (e.g. see 'Examples' section in
linkgit:git-update-index[1]).
Git will not normally detect changes to those files.
+
This is useful on systems where lstat() calls are very slow, such as
CIFS/Microsoft Windows.
+
False by default.

core.preferSymlinkRefs::
        Instead of the default "symref" format for HEAD
        and other symbolic reference files, use symbolic links.
        This is sometimes needed to work with old scripts that
        expect HEAD to be a symbolic link.

core.bare::
        If true this repository is assumed to be 'bare' and has no
        working directory associated with it.  If this is the case a
        number of commands that require a working directory will be
        disabled, such as linkgit:git-add[1] or linkgit:git-merge[1].
+
This setting is automatically guessed by linkgit:git-clone[1] or
linkgit:git-init[1] when the repository was created.  By default a
repository that ends in "/.git" is assumed to be not bare (bare =
false), while all other repositories are assumed to be bare (bare
= true).

core.worktree::
        Set the path to the root of the working tree.
        This can be overridden by the GIT_WORK_TREE environment
        variable and the '--work-tree' command-line option.
        The value can be an absolute path or relative to the path to
        the .git directory, which is either specified by --git-dir
        or GIT_DIR, or automatically discovered.
        If --git-dir or GIT_DIR is specified but none of
        --work-tree, GIT_WORK_TREE and core.worktree is specified,
        the current working directory is regarded as the top level
        of your working tree.
+
Note that this variable is honored even when set in a configuration
file in a ".git" subdirectory of a directory and its value differs
from the latter directory (e.g. "/path/to/.git/config" has
core.worktree set to "/different/path"), which is most likely a
misconfiguration.  Running Git commands in the "/path/to" directory will
still use "/different/path" as the root of the work tree and can cause
confusion unless you know what you are doing (e.g. you are creating a
read-only snapshot of the same index to a location different from the
repository's usual working tree).

core.logAllRefUpdates::
        Enable the reflog. Updates to a ref <ref> is logged to the file
        "$GIT_DIR/logs/<ref>", by appending the new and old
        SHA-1, the date/time and the reason of the update, but
        only when the file exists.  If this configuration
        variable is set to true, missing "$GIT_DIR/logs/<ref>"
        file is automatically created for branch heads (i.e. under
        refs/heads/), remote refs (i.e. under refs/remotes/),
        note refs (i.e. under refs/notes/), and the symbolic ref HEAD.
+
This information can be used to determine what commit
was the tip of a branch "2 days ago".
+
This value is true by default in a repository that has
a working directory associated with it, and false by
default in a bare repository.

core.repositoryFormatVersion::
        Internal variable identifying the repository format and layout
        version.

core.sharedRepository::
        When 'group' (or 'true'), the repository is made shareable between
        several users in a group (making sure all the files and objects are
        group-writable). When 'all' (or 'world' or 'everybody'), the
        repository will be readable by all users, additionally to being
        group-shareable. When 'umask' (or 'false'), Git will use permissions
        reported by umask(2). When '0xxx', where '0xxx' is an octal number,
        files in the repository will have this mode value. '0xxx' will override
        user's umask value (whereas the other options will only override
        requested parts of the user's umask value). Examples: '0660' will make
        the repo read/write-able for the owner and group, but inaccessible to
        others (equivalent to 'group' unless umask is e.g. '0022'). '0640' is a
        repository that is group-readable but not group-writable.
        See linkgit:git-init[1]. False by default.

core.warnAmbiguousRefs::
        If true, Git will warn you if the ref name you passed it is ambiguous
        and might match multiple refs in the repository. True by default.

core.compression::
        An integer -1..9, indicating a default compression level.
        -1 is the zlib default. 0 means no compression,
        and 1..9 are various speed/size tradeoffs, 9 being slowest.
        If set, this provides a default to other compression variables,
        such as 'core.loosecompression' and 'pack.compression'.

core.loosecompression::
        An integer -1..9, indicating the compression level for objects that
        are not in a pack file. -1 is the zlib default. 0 means no
        compression, and 1..9 are various speed/size tradeoffs, 9 being
        slowest.  If not set,  defaults to core.compression.  If that is
        not set,  defaults to 1 (best speed).

core.packedGitWindowSize::
        Number of bytes of a pack file to map into memory in a
        single mapping operation.  Larger window sizes may allow
        your system to process a smaller number of large pack files
        more quickly.  Smaller window sizes will negatively affect
        performance due to increased calls to the operating system's
        memory manager, but may improve performance when accessing
        a large number of large pack files.
+
Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
MiB on 32 bit platforms and 1 GiB on 64 bit platforms.  This should
be reasonable for all users/operating systems.  You probably do
not need to adjust this value.
+
Common unit suffixes of 'k', 'm', or 'g' are supported.

core.packedGitLimit::
        Maximum number of bytes to map simultaneously into memory
        from pack files.  If Git needs to access more than this many
        bytes at once to complete an operation it will unmap existing
        regions to reclaim virtual address space within the process.
+
Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms.
This should be reasonable for all users/operating systems, except on
the largest projects.  You probably do not need to adjust this value.
+
Common unit suffixes of 'k', 'm', or 'g' are supported.

core.deltaBaseCacheLimit::
        Maximum number of bytes to reserve for caching base objects
        that may be referenced by multiple deltified objects.  By storing the
        entire decompressed base objects in a cache Git is able
        to avoid unpacking and decompressing frequently used base
        objects multiple times.
+
Default is 96 MiB on all platforms.  This should be reasonable
for all users/operating systems, except on the largest projects.
You probably do not need to adjust this value.
+
Common unit suffixes of 'k', 'm', or 'g' are supported.

core.bigFileThreshold::
        Files larger than this size are stored deflated, without
        attempting delta compression.  Storing large files without
        delta compression avoids excessive memory usage, at the
        slight expense of increased disk usage. Additionally files
        larger than this size are always treated as binary.
+
Default is 512 MiB on all platforms.  This should be reasonable
for most projects as source code and other text files can still
be delta compressed, but larger binary media files won't be.
+
Common unit suffixes of 'k', 'm', or 'g' are supported.

core.excludesfile::
        In addition to '.gitignore' (per-directory) and
        '.git/info/exclude', Git looks into this file for patterns
        of files which are not meant to be tracked.  "`~/`" is expanded
        to the value of `$HOME` and "`~user/`" to the specified user's
        home directory. Its default value is $XDG_CONFIG_HOME/git/ignore.
        If $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/ignore
        is used instead. See linkgit:gitignore[5].

core.askpass::
        Some commands (e.g. svn and http interfaces) that interactively
        ask for a password can be told to use an external program given
        via the value of this variable. Can be overridden by the 'GIT_ASKPASS'
        environment variable. If not set, fall back to the value of the
        'SSH_ASKPASS' environment variable or, failing that, a simple password
        prompt. The external program shall be given a suitable prompt as
        command-line argument and write the password on its STDOUT.

core.attributesfile::
        In addition to '.gitattributes' (per-directory) and
        '.git/info/attributes', Git looks into this file for attributes
        (see linkgit:gitattributes[5]). Path expansions are made the same
        way as for `core.excludesfile`. Its default value is
        $XDG_CONFIG_HOME/git/attributes. If $XDG_CONFIG_HOME is either not
        set or empty, $HOME/.config/git/attributes is used instead.

core.editor::
        Commands such as `commit` and `tag` that lets you edit
        messages by launching an editor uses the value of this
        variable when it is set, and the environment variable
        `GIT_EDITOR` is not set.  See linkgit:git-var[1].

core.commentchar::
        Commands such as `commit` and `tag` that lets you edit
        messages consider a line that begins with this character
        commented, and removes them after the editor returns
        (default '#').
+
If set to "auto", `git-commit` would select a character that is not
the beginning character of any line in existing commit messages.

sequence.editor::
        Text editor used by `git rebase -i` for editing the rebase instruction file.
        The value is meant to be interpreted by the shell when it is used.
        It can be overridden by the `GIT_SEQUENCE_EDITOR` environment variable.
        When not configured the default commit message editor is used instead.

core.pager::
        Text viewer for use by Git commands (e.g., 'less').  The value
        is meant to be interpreted by the shell.  The order of preference
        is the `$GIT_PAGER` environment variable, then `core.pager`
        configuration, then `$PAGER`, and then the default chosen at
        compile time (usually 'less').
+
When the `LESS` environment variable is unset, Git sets it to `FRX`
(if `LESS` environment variable is set, Git does not change it at
all).  If you want to selectively override Git's default setting
for `LESS`, you can set `core.pager` to e.g. `less -S`.  This will
be passed to the shell by Git, which will translate the final
command to `LESS=FRX less -S`. The environment does not set the
`S` option but the command line does, instructing less to truncate
long lines. Similarly, setting `core.pager` to `less -+F` will
deactivate the `F` option specified by the environment from the
command-line, deactivating the "quit if one screen" behavior of
`less`.  One can specifically activate some flags for particular
commands: for example, setting `pager.blame` to `less -S` enables
line truncation only for `git blame`.
+
Likewise, when the `LV` environment variable is unset, Git sets it
to `-c`.  You can override this setting by exporting `LV` with
another value or setting `core.pager` to `lv +c`.

core.whitespace::
        A comma separated list of common whitespace problems to
        notice.  'git diff' will use `color.diff.whitespace` to
        highlight them, and 'git apply --whitespace=error' will
        consider them as errors.  You can prefix `-` to disable
        any of them (e.g. `-trailing-space`):
+
* `blank-at-eol` treats trailing whitespaces at the end of the line
  as an error (enabled by default).
* `space-before-tab` treats a space character that appears immediately
  before a tab character in the initial indent part of the line as an
  error (enabled by default).
* `indent-with-non-tab` treats a line that is indented with space
  characters instead of the equivalent tabs as an error (not enabled by
  default).
* `tab-in-indent` treats a tab character in the initial indent part of
  the line as an error (not enabled by default).
* `blank-at-eof` treats blank lines added at the end of file as an error
  (enabled by default).
* `trailing-space` is a short-hand to cover both `blank-at-eol` and
  `blank-at-eof`.
* `cr-at-eol` treats a carriage-return at the end of line as
  part of the line terminator, i.e. with it, `trailing-space`
  does not trigger if the character before such a carriage-return
  is not a whitespace (not enabled by default).
* `tabwidth=<n>` tells how many character positions a tab occupies; this
  is relevant for `indent-with-non-tab` and when Git fixes `tab-in-indent`
  errors. The default tab width is 8. Allowed values are 1 to 63.

core.fsyncobjectfiles::
        This boolean will enable 'fsync()' when writing object files.
+
This is a total waste of time and effort on a filesystem that orders
data writes properly, but can be useful for filesystems that do not use
journalling (traditional UNIX filesystems) or that only journal metadata
and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").

core.preloadindex::
        Enable parallel index preload for operations like 'git diff'
+
This can speed up operations like 'git diff' and 'git status' especially
on filesystems like NFS that have weak caching semantics and thus
relatively high IO latencies.  When enabled, Git will do the
index comparison to the filesystem data in parallel, allowing
overlapping IO's.  Defaults to true.

core.createObject::
        You can set this to 'link', in which case a hardlink followed by
        a delete of the source are used to make sure that object creation
        will not overwrite existing objects.
+
On some file system/operating system combinations, this is unreliable.
Set this config setting to 'rename' there; However, This will remove the
check that makes sure that existing object files will not get overwritten.

core.notesRef::
        When showing commit messages, also show notes which are stored in
        the given ref.  The ref must be fully qualified.  If the given
        ref does not exist, it is not an error but means that no
        notes should be printed.
+
This setting defaults to "refs/notes/commits", and it can be overridden by
the 'GIT_NOTES_REF' environment variable.  See linkgit:git-notes[1].

core.sparseCheckout::
        Enable "sparse checkout" feature. See section "Sparse checkout" in
        linkgit:git-read-tree[1] for more information.

core.abbrev::
        Set the length object names are abbreviated to.  If unspecified,
        many commands abbreviate to 7 hexdigits, which may not be enough
        for abbreviated object names to stay unique for sufficiently long
        time.

add.ignoreErrors::
add.ignore-errors (deprecated)::
        Tells 'git add' to continue adding files when some files cannot be
        added due to indexing errors. Equivalent to the '--ignore-errors'
        option of linkgit:git-add[1].  `add.ignore-errors` is deprecated,
        as it does not follow the usual naming convention for configuration
        variables.

alias.*::
        Command aliases for the linkgit:git[1] command wrapper - e.g.
        after defining "alias.last = cat-file commit HEAD", the invocation
        "git last" is equivalent to "git cat-file commit HEAD". To avoid
        confusion and troubles with script usage, aliases that
        hide existing Git commands are ignored. Arguments are split by
        spaces, the usual shell quoting and escaping is supported.
        A quote pair or a backslash can be used to quote them.
+
If the alias expansion is prefixed with an exclamation point,
it will be treated as a shell command.  For example, defining
"alias.new = !gitk --all --not ORIG_HEAD", the invocation
"git new" is equivalent to running the shell command
"gitk --all --not ORIG_HEAD".  Note that shell commands will be
executed from the top-level directory of a repository, which may
not necessarily be the current directory.
'GIT_PREFIX' is set as returned by running 'git rev-parse --show-prefix'
from the original current directory. See linkgit:git-rev-parse[1].

am.keepcr::
        If true, git-am will call git-mailsplit for patches in mbox format
        with parameter '--keep-cr'. In this case git-mailsplit will
        not remove `\r` from lines ending with `\r\n`. Can be overridden
        by giving '--no-keep-cr' from the command line.
        See linkgit:git-am[1], linkgit:git-mailsplit[1].

apply.ignorewhitespace::
        When set to 'change', tells 'git apply' to ignore changes in
        whitespace, in the same way as the '--ignore-space-change'
        option.
        When set to one of: no, none, never, false tells 'git apply' to
        respect all whitespace differences.
        See linkgit:git-apply[1].

apply.whitespace::
        Tells 'git apply' how to handle whitespaces, in the same way
        as the '--whitespace' option. See linkgit:git-apply[1].

branch.autosetupmerge::
        Tells 'git branch' and 'git checkout' to set up new branches
        so that linkgit:git-pull[1] will appropriately merge from the
        starting point branch. Note that even if this option is not set,
        this behavior can be chosen per-branch using the `--track`
        and `--no-track` options. The valid settings are: `false` -- no
        automatic setup is done; `true` -- automatic setup is done when the
        starting point is a remote-tracking branch; `always` --
        automatic setup is done when the starting point is either a
        local branch or remote-tracking
        branch. This option defaults to true.

branch.autosetuprebase::
        When a new branch is created with 'git branch' or 'git checkout'
        that tracks another branch, this variable tells Git to set
        up pull to rebase instead of merge (see "branch.<name>.rebase").
        When `never`, rebase is never automatically set to true.
        When `local`, rebase is set to true for tracked branches of
        other local branches.
        When `remote`, rebase is set to true for tracked branches of
        remote-tracking branches.
        When `always`, rebase will be set to true for all tracking
        branches.
        See "branch.autosetupmerge" for details on how to set up a
        branch to track another branch.
        This option defaults to never.

branch.<name>.remote::
        When on branch <name>, it tells 'git fetch' and 'git push'
        which remote to fetch from/push to.  The remote to push to
        may be overridden with `remote.pushdefault` (for all branches).
        The remote to push to, for the current branch, may be further
        overridden by `branch.<name>.pushremote`.  If no remote is
        configured, or if you are not on any branch, it defaults to
        `origin` for fetching and `remote.pushdefault` for pushing.
        Additionally, `.` (a period) is the current local repository
        (a dot-repository), see `branch.<name>.merge`'s final note below.

branch.<name>.pushremote::
        When on branch <name>, it overrides `branch.<name>.remote` for
        pushing.  It also overrides `remote.pushdefault` for pushing
        from branch <name>.  When you pull from one place (e.g. your
        upstream) and push to another place (e.g. your own publishing
        repository), you would want to set `remote.pushdefault` to
        specify the remote to push to for all branches, and use this
        option to override it for a specific branch.

branch.<name>.merge::
        Defines, together with branch.<name>.remote, the upstream branch
        for the given branch. It tells 'git fetch'/'git pull'/'git rebase' which
        branch to merge and can also affect 'git push' (see push.default).
        When in branch <name>, it tells 'git fetch' the default
        refspec to be marked for merging in FETCH_HEAD. The value is
        handled like the remote part of a refspec, and must match a
        ref which is fetched from the remote given by
        "branch.<name>.remote".
        The merge information is used by 'git pull' (which at first calls
        'git fetch') to lookup the default branch for merging. Without
        this option, 'git pull' defaults to merge the first refspec fetched.
        Specify multiple values to get an octopus merge.
        If you wish to setup 'git pull' so that it merges into <name> from
        another branch in the local repository, you can point
        branch.<name>.merge to the desired branch, and use the relative path
        setting `.` (a period) for branch.<name>.remote.

branch.<name>.mergeoptions::
        Sets default options for merging into branch <name>. The syntax and
        supported options are the same as those of linkgit:git-merge[1], but
        option values containing whitespace characters are currently not
        supported.

branch.<name>.rebase::
        When true, rebase the branch <name> on top of the fetched branch,
        instead of merging the default branch from the default remote when
        "git pull" is run. See "pull.rebase" for doing this in a non
        branch-specific manner.
+
        When preserve, also pass `--preserve-merges` along to 'git rebase'
        so that locally committed merge commits will not be flattened
        by running 'git pull'.
+
*NOTE*: this is a possibly dangerous operation; do *not* use
it unless you understand the implications (see linkgit:git-rebase[1]
for details).

branch.<name>.description::
        Branch description, can be edited with
        `git branch --edit-description`. Branch description is
        automatically added in the format-patch cover letter or
        request-pull summary.

browser.<tool>.cmd::
        Specify the command to invoke the specified browser. The
        specified command is evaluated in shell with the URLs passed
        as arguments. (See linkgit:git-web{litdd}browse[1].)

browser.<tool>.path::
        Override the path for the given tool that may be used to
        browse HTML help (see '-w' option in linkgit:git-help[1]) or a
        working repository in gitweb (see linkgit:git-instaweb[1]).

clean.requireForce::
        A boolean to make git-clean do nothing unless given -f,
        -i or -n.   Defaults to true.

color.branch::
        A boolean to enable/disable color in the output of
        linkgit:git-branch[1]. May be set to `always`,
        `false` (or `never`) or `auto` (or `true`), in which case colors are used
        only when the output is to a terminal. Defaults to false.

color.branch.<slot>::
        Use customized color for branch coloration. `<slot>` is one of
        `current` (the current branch), `local` (a local branch),
        `remote` (a remote-tracking branch in refs/remotes/),
        `upstream` (upstream tracking branch), `plain` (other
        refs).
+
The value for these configuration variables is a list of colors (at most
two) and attributes (at most one), separated by spaces.  The colors
accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`,
`magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`,
`blink` and `reverse`.  The first color given is the foreground; the
second is the background.  The position of the attribute, if any,
doesn't matter. Attributes may be turned off specifically by prefixing
them with `no` (e.g., `noreverse`, `noul`, etc).
+
Colors (foreground and background) may also be given as numbers between
0 and 255; these use ANSI 256-color mode (but note that not all
terminals may support this).  If your terminal supports it, you may also
specify 24-bit RGB values as hex, like `#ff0ab3`.

color.diff::
        Whether to use ANSI escape sequences to add color to patches.
        If this is set to `always`, linkgit:git-diff[1],
        linkgit:git-log[1], and linkgit:git-show[1] will use color
        for all patches.  If it is set to `true` or `auto`, those
        commands will only use color when output is to the terminal.
        Defaults to false.
+
This does not affect linkgit:git-format-patch[1] or the
'git-diff-{asterisk}' plumbing commands.  Can be overridden on the
command line with the `--color[=<when>]` option.

color.diff.<slot>::
        Use customized color for diff colorization.  `<slot>` specifies
        which part of the patch to use the specified color, and is one
        of `plain` (context text), `meta` (metainformation), `frag`
        (hunk header), 'func' (function in hunk header), `old` (removed lines),
        `new` (added lines), `commit` (commit headers), or `whitespace`
        (highlighting whitespace errors). The values of these variables may be
        specified as in color.branch.<slot>.

color.decorate.<slot>::
        Use customized color for 'git log --decorate' output.  `<slot>` is one
        of `branch`, `remoteBranch`, `tag`, `stash` or `HEAD` for local
        branches, remote-tracking branches, tags, stash and HEAD, respectively.

color.grep::
        When set to `always`, always highlight matches.  When `false` (or
        `never`), never.  When set to `true` or `auto`, use color only
        when the output is written to the terminal.  Defaults to `false`.

color.grep.<slot>::
        Use customized color for grep colorization.  `<slot>` specifies which
        part of the line to use the specified color, and is one of
+
--
`context`;;
        non-matching text in context lines (when using `-A`, `-B`, or `-C`)
`filename`;;
        filename prefix (when not using `-h`)
`function`;;
        function name lines (when using `-p`)
`linenumber`;;
        line number prefix (when using `-n`)
`match`;;
        matching text (same as setting `matchContext` and `matchSelected`)
`matchContext`;;
        matching text in context lines
`matchSelected`;;
        matching text in selected lines
`selected`;;
        non-matching text in selected lines
`separator`;;
        separators between fields on a line (`:`, `-`, and `=`)
        and between hunks (`--`)
--
+
The values of these variables may be specified as in color.branch.<slot>.

color.interactive::
        When set to `always`, always use colors for interactive prompts
        and displays (such as those used by "git-add --interactive" and
        "git-clean --interactive"). When false (or `never`), never.
        When set to `true` or `auto`, use colors only when the output is
        to the terminal. Defaults to false.

color.interactive.<slot>::
        Use customized color for 'git add --interactive' and 'git clean
        --interactive' output. `<slot>` may be `prompt`, `header`, `help`
        or `error`, for four distinct types of normal output from
        interactive commands.  The values of these variables may be
        specified as in color.branch.<slot>.

color.pager::
        A boolean to enable/disable colored output when the pager is in
        use (default is true).

color.showbranch::
        A boolean to enable/disable color in the output of
        linkgit:git-show-branch[1]. May be set to `always`,
        `false` (or `never`) or `auto` (or `true`), in which case colors are used
        only when the output is to a terminal. Defaults to false.

color.status::
        A boolean to enable/disable color in the output of
        linkgit:git-status[1]. May be set to `always`,
        `false` (or `never`) or `auto` (or `true`), in which case colors are used
        only when the output is to a terminal. Defaults to false.

color.status.<slot>::
        Use customized color for status colorization. `<slot>` is
        one of `header` (the header text of the status message),
        `added` or `updated` (files which are added but not committed),
        `changed` (files which are changed but not added in the index),
        `untracked` (files which are not tracked by Git),
        `branch` (the current branch), or
        `nobranch` (the color the 'no branch' warning is shown in, defaulting
        to red). The values of these variables may be specified as in
        color.branch.<slot>.

color.ui::
        This variable determines the default value for variables such
        as `color.diff` and `color.grep` that control the use of color
        per command family. Its scope will expand as more commands learn
        configuration to set a default for the `--color` option.  Set it
        to `false` or `never` if you prefer Git commands not to use
        color unless enabled explicitly with some other configuration
        or the `--color` option. Set it to `always` if you want all
        output not intended for machine consumption to use color, to
        `true` or `auto` (this is the default since Git 1.8.4) if you
        want such output to use color when written to the terminal.

column.ui::
        Specify whether supported commands should output in columns.
        This variable consists of a list of tokens separated by spaces
        or commas:
+
These options control when the feature should be enabled
(defaults to 'never'):
+
--
`always`;;
        always show in columns
`never`;;
        never show in columns
`auto`;;
        show in columns if the output is to the terminal
--
+
These options control layout (defaults to 'column').  Setting any
of these implies 'always' if none of 'always', 'never', or 'auto' are
specified.
+
--
`column`;;
        fill columns before rows
`row`;;
        fill rows before columns
`plain`;;
        show in one column
--
+
Finally, these options can be combined with a layout option (defaults
to 'nodense'):
+
--
`dense`;;
        make unequal size columns to utilize more space
`nodense`;;
        make equal size columns
--

column.branch::
        Specify whether to output branch listing in `git branch` in columns.
        See `column.ui` for details.

column.clean::
        Specify the layout when list items in `git clean -i`, which always
        shows files and directories in columns. See `column.ui` for details.

column.status::
        Specify whether to output untracked files in `git status` in columns.
        See `column.ui` for details.

column.tag::
        Specify whether to output tag listing in `git tag` in columns.
        See `column.ui` for details.

commit.cleanup::
        This setting overrides the default of the `--cleanup` option in
        `git commit`. See linkgit:git-commit[1] for details. Changing the
        default can be useful when you always want to keep lines that begin
        with comment character `#` in your log message, in which case you
        would do `git config commit.cleanup whitespace` (note that you will
        have to remove the help lines that begin with `#` in the commit log
        template yourself, if you do this).

commit.gpgsign::

        A boolean to specify whether all commits should be GPG signed.
        Use of this option when doing operations such as rebase can
        result in a large number of commits being signed. It may be
        convenient to use an agent to avoid typing your GPG passphrase
        several times.

commit.status::
        A boolean to enable/disable inclusion of status information in the
        commit message template when using an editor to prepare the commit
        message.  Defaults to true.

commit.template::
        Specify a file to use as the template for new commit messages.
        "`~/`" is expanded to the value of `$HOME` and "`~user/`" to the
        specified user's home directory.

credential.helper::
        Specify an external helper to be called when a username or
        password credential is needed; the helper may consult external
        storage to avoid prompting the user for the credentials. See
        linkgit:gitcredentials[7] for details.

credential.useHttpPath::
        When acquiring credentials, consider the "path" component of an http
        or https URL to be important. Defaults to false. See
        linkgit:gitcredentials[7] for more information.

credential.username::
        If no username is set for a network authentication, use this username
        by default. See credential.<context>.* below, and
        linkgit:gitcredentials[7].

credential.<url>.*::
        Any of the credential.* options above can be applied selectively to
        some credentials. For example "credential.https://example.com.username"
        would set the default username only for https connections to
        example.com. See linkgit:gitcredentials[7] for details on how URLs are
        matched.

include::diff-config.txt[]

difftool.<tool>.path::
        Override the path for the given tool.  This is useful in case
        your tool is not in the PATH.

difftool.<tool>.cmd::
        Specify the command to invoke the specified diff tool.
        The specified command is evaluated in shell with the following
        variables available:  'LOCAL' is set to the name of the temporary
        file containing the contents of the diff pre-image and 'REMOTE'
        is set to the name of the temporary file containing the contents
        of the diff post-image.

difftool.prompt::
        Prompt before each invocation of the diff tool.

fetch.recurseSubmodules::
        This option can be either set to a boolean value or to 'on-demand'.
        Setting it to a boolean changes the behavior of fetch and pull to
        unconditionally recurse into submodules when set to true or to not
        recurse at all when set to false. When set to 'on-demand' (the default
        value), fetch and pull will only recurse into a populated submodule
        when its superproject retrieves a commit that updates the submodule's
        reference.

fetch.fsckObjects::
        If it is set to true, git-fetch-pack will check all fetched
        objects. It will abort in the case of a malformed object or a
        broken link. The result of an abort are only dangling objects.
        Defaults to false. If not set, the value of `transfer.fsckObjects`
        is used instead.

fetch.unpackLimit::
        If the number of objects fetched over the Git native
        transfer is below this
        limit, then the objects will be unpacked into loose object
        files. However if the number of received objects equals or
        exceeds this limit then the received pack will be stored as
        a pack, after adding any missing delta bases.  Storing the
        pack from a push can make the push operation complete faster,
        especially on slow filesystems.  If not set, the value of
        `transfer.unpackLimit` is used instead.

fetch.prune::
        If true, fetch will automatically behave as if the `--prune`
        option was given on the command line.  See also `remote.<name>.prune`.

format.attach::
        Enable multipart/mixed attachments as the default for
        'format-patch'.  The value can also be a double quoted string
        which will enable attachments as the default and set the
        value as the boundary.  See the --attach option in
        linkgit:git-format-patch[1].

format.numbered::
        A boolean which can enable or disable sequence numbers in patch
        subjects.  It defaults to "auto" which enables it only if there
        is more than one patch.  It can be enabled or disabled for all
        messages by setting it to "true" or "false".  See --numbered
        option in linkgit:git-format-patch[1].

format.headers::
        Additional email headers to include in a patch to be submitted
        by mail.  See linkgit:git-format-patch[1].

format.to::
format.cc::
        Additional recipients to include in a patch to be submitted
        by mail.  See the --to and --cc options in
        linkgit:git-format-patch[1].

format.subjectprefix::
        The default for format-patch is to output files with the '[PATCH]'
        subject prefix. Use this variable to change that prefix.

format.signature::
        The default for format-patch is to output a signature containing
        the Git version number. Use this variable to change that default.
        Set this variable to the empty string ("") to suppress
        signature generation.

format.signaturefile::
        Works just like format.signature except the contents of the
        file specified by this variable will be used as the signature.

format.suffix::
        The default for format-patch is to output files with the suffix
        `.patch`. Use this variable to change that suffix (make sure to
        include the dot if you want it).

format.pretty::
        The default pretty format for log/show/whatchanged command,
        See linkgit:git-log[1], linkgit:git-show[1],
        linkgit:git-whatchanged[1].

format.thread::
        The default threading style for 'git format-patch'.  Can be
        a boolean value, or `shallow` or `deep`.  `shallow` threading
        makes every mail a reply to the head of the series,
        where the head is chosen from the cover letter, the
        `--in-reply-to`, and the first patch mail, in this order.
        `deep` threading makes every mail a reply to the previous one.
        A true boolean value is the same as `shallow`, and a false
        value disables threading.

format.signoff::
        A boolean value which lets you enable the `-s/--signoff` option of
        format-patch by default. *Note:* Adding the Signed-off-by: line to a
        patch should be a conscious act and means that you certify you have
        the rights to submit this work under the same open source license.
        Please see the 'SubmittingPatches' document for further discussion.

format.coverLetter::
        A boolean that controls whether to generate a cover-letter when
        format-patch is invoked, but in addition can be set to "auto", to
        generate a cover-letter only when there's more than one patch.

filter.<driver>.clean::
        The command which is used to convert the content of a worktree
        file to a blob upon checkin.  See linkgit:gitattributes[5] for
        details.

filter.<driver>.smudge::
        The command which is used to convert the content of a blob
        object to a worktree file upon checkout.  See
        linkgit:gitattributes[5] for details.

gc.aggressiveDepth::
        The depth parameter used in the delta compression
        algorithm used by 'git gc --aggressive'.  This defaults
        to 250.

gc.aggressiveWindow::
        The window size parameter used in the delta compression
        algorithm used by 'git gc --aggressive'.  This defaults
        to 250.

gc.auto::
        When there are approximately more than this many loose
        objects in the repository, `git gc --auto` will pack them.
        Some Porcelain commands use this command to perform a
        light-weight garbage collection from time to time.  The
        default value is 6700.  Setting this to 0 disables it.

gc.autopacklimit::
        When there are more than this many packs that are not
        marked with `*.keep` file in the repository, `git gc
        --auto` consolidates them into one larger pack.  The
        default value is 50.  Setting this to 0 disables it.

gc.autodetach::
        Make `git gc --auto` return immediately and run in background
        if the system supports it. Default is true.

gc.packrefs::
        Running `git pack-refs` in a repository renders it
        unclonable by Git versions prior to 1.5.1.2 over dumb
        transports such as HTTP.  This variable determines whether
        'git gc' runs `git pack-refs`. This can be set to `notbare`
        to enable it within all non-bare repos or it can be set to a
        boolean value.  The default is `true`.

gc.pruneexpire::
        When 'git gc' is run, it will call 'prune --expire 2.weeks.ago'.
        Override the grace period with this config variable.  The value
        "now" may be used to disable this  grace period and always prune
        unreachable objects immediately.

gc.reflogexpire::
gc.<pattern>.reflogexpire::
        'git reflog expire' removes reflog entries older than
        this time; defaults to 90 days.  With "<pattern>" (e.g.
        "refs/stash") in the middle the setting applies only to
        the refs that match the <pattern>.

gc.reflogexpireunreachable::
gc.<ref>.reflogexpireunreachable::
        'git reflog expire' removes reflog entries older than
        this time and are not reachable from the current tip;
        defaults to 30 days.  With "<pattern>" (e.g. "refs/stash")
        in the middle, the setting applies only to the refs that
        match the <pattern>.

gc.rerereresolved::
        Records of conflicted merge you resolved earlier are
        kept for this many days when 'git rerere gc' is run.
        The default is 60 days.  See linkgit:git-rerere[1].

gc.rerereunresolved::
        Records of conflicted merge you have not resolved are
        kept for this many days when 'git rerere gc' is run.
        The default is 15 days.  See linkgit:git-rerere[1].

gitcvs.commitmsgannotation::
        Append this string to each commit message. Set to empty string
        to disable this feature. Defaults to "via git-CVS emulator".

gitcvs.enabled::
        Whether the CVS server interface is enabled for this repository.
        See linkgit:git-cvsserver[1].

gitcvs.logfile::
        Path to a log file where the CVS server interface well... logs
        various stuff. See linkgit:git-cvsserver[1].

gitcvs.usecrlfattr::
        If true, the server will look up the end-of-line conversion
        attributes for files to determine the '-k' modes to use. If
        the attributes force Git to treat a file as text,
        the '-k' mode will be left blank so CVS clients will
        treat it as text. If they suppress text conversion, the file
        will be set with '-kb' mode, which suppresses any newline munging
        the client might otherwise do. If the attributes do not allow
        the file type to be determined, then 'gitcvs.allbinary' is
        used. See linkgit:gitattributes[5].

gitcvs.allbinary::
        This is used if 'gitcvs.usecrlfattr' does not resolve
        the correct '-kb' mode to use. If true, all
        unresolved files are sent to the client in
        mode '-kb'. This causes the client to treat them
        as binary files, which suppresses any newline munging it
        otherwise might do. Alternatively, if it is set to "guess",
        then the contents of the file are examined to decide if
        it is binary, similar to 'core.autocrlf'.

gitcvs.dbname::
        Database used by git-cvsserver to cache revision information
        derived from the Git repository. The exact meaning depends on the
        used database driver, for SQLite (which is the default driver) this
        is a filename. Supports variable substitution (see
        linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`).
        Default: '%Ggitcvs.%m.sqlite'

gitcvs.dbdriver::
        Used Perl DBI driver. You can specify any available driver
        for this here, but it might not work. git-cvsserver is tested
        with 'DBD::SQLite', reported to work with 'DBD::Pg', and
        reported *not* to work with 'DBD::mysql'. Experimental feature.
        May not contain double colons (`:`). Default: 'SQLite'.
        See linkgit:git-cvsserver[1].

gitcvs.dbuser, gitcvs.dbpass::
        Database user and password. Only useful if setting 'gitcvs.dbdriver',
        since SQLite has no concept of database users and/or passwords.
        'gitcvs.dbuser' supports variable substitution (see
        linkgit:git-cvsserver[1] for details).

gitcvs.dbTableNamePrefix::
        Database table name prefix.  Prepended to the names of any
        database tables used, allowing a single database to be used
        for several repositories.  Supports variable substitution (see
        linkgit:git-cvsserver[1] for details).  Any non-alphabetic
        characters will be replaced with underscores.

All gitcvs variables except for 'gitcvs.usecrlfattr' and
'gitcvs.allbinary' can also be specified as
'gitcvs.<access_method>.<varname>' (where 'access_method'
is one of "ext" and "pserver") to make them apply only for the given
access method.

gitweb.category::
gitweb.description::
gitweb.owner::
gitweb.url::
        See linkgit:gitweb[1] for description.

gitweb.avatar::
gitweb.blame::
gitweb.grep::

gitweb.patches::
gitweb.pickaxe::
gitweb.remote_heads::
gitweb.showsizes::
gitweb.snapshot::
        See linkgit:gitweb.conf[5] for description.

grep.lineNumber::
        If set to true, enable '-n' option by default.

grep.patternType::
        Set the default matching behavior. Using a value of 'basic', 'extended',
        'fixed', or 'perl' will enable the '--basic-regexp', '--extended-regexp',
        '--fixed-strings', or '--perl-regexp' option accordingly, while the
        value 'default' will return to the default matching behavior.

grep.extendedRegexp::
        If set to true, enable '--extended-regexp' option by default. This
        option is ignored when the 'grep.patternType' option is set to a value
        other than 'default'.

gpg.program::
        Use this custom program instead of "gpg" found on $PATH when
        making or verifying a PGP signature. The program must support the
        same command-line interface as GPG, namely, to verify a detached
        signature, "gpg --verify $file - <$signature" is run, and the
        program is expected to signal a good signature by exiting with
        code 0, and to generate an ASCII-armored detached signature, the
        standard input of "gpg -bsau $key" is fed with the contents to be
        signed, and the program is expected to send the result to its
        standard output.

gui.commitmsgwidth::
        Defines how wide the commit message window is in the
        linkgit:git-gui[1]. "75" is the default.

gui.diffcontext::
        Specifies how many context lines should be used in calls to diff
        made by the linkgit:git-gui[1]. The default is "5".

gui.displayuntracked::
        Determines if linkgit::git-gui[1] shows untracked files
        in the file list. The default is "true".

gui.encoding::
        Specifies the default encoding to use for displaying of
        file contents in linkgit:git-gui[1] and linkgit:gitk[1].
        It can be overridden by setting the 'encoding' attribute
        for relevant files (see linkgit:gitattributes[5]).
        If this option is not set, the tools default to the
        locale encoding.

gui.matchtrackingbranch::
        Determines if new branches created with linkgit:git-gui[1] should
        default to tracking remote branches with matching names or
        not. Default: "false".

gui.newbranchtemplate::
        Is used as suggested name when creating new branches using the
        linkgit:git-gui[1].

gui.pruneduringfetch::
        "true" if linkgit:git-gui[1] should prune remote-tracking branches when
        performing a fetch. The default value is "false".

gui.trustmtime::
        Determines if linkgit:git-gui[1] should trust the file modification
        timestamp or not. By default the timestamps are not trusted.

gui.spellingdictionary::
        Specifies the dictionary used for spell checking commit messages in
        the linkgit:git-gui[1]. When set to "none" spell checking is turned
        off.

gui.fastcopyblame::
        If true, 'git gui blame' uses `-C` instead of `-C -C` for original
        location detection. It makes blame significantly faster on huge
        repositories at the expense of less thorough copy detection.

gui.copyblamethreshold::
        Specifies the threshold to use in 'git gui blame' original location
        detection, measured in alphanumeric characters. See the
        linkgit:git-blame[1] manual for more information on copy detection.

gui.blamehistoryctx::
        Specifies the radius of history context in days to show in
        linkgit:gitk[1] for the selected commit, when the `Show History
        Context` menu item is invoked from 'git gui blame'. If this
        variable is set to zero, the whole history is shown.

guitool.<name>.cmd::
        Specifies the shell command line to execute when the corresponding item
        of the linkgit:git-gui[1] `Tools` menu is invoked. This option is
        mandatory for every tool. The command is executed from the root of
        the working directory, and in the environment it receives the name of
        the tool as 'GIT_GUITOOL', the name of the currently selected file as
        'FILENAME', and the name of the current branch as 'CUR_BRANCH' (if
        the head is detached, 'CUR_BRANCH' is empty).

guitool.<name>.needsfile::
        Run the tool only if a diff is selected in the GUI. It guarantees
        that 'FILENAME' is not empty.

guitool.<name>.noconsole::
        Run the command silently, without creating a window to display its
        output.

guitool.<name>.norescan::
        Don't rescan the working directory for changes after the tool
        finishes execution.

guitool.<name>.confirm::
        Show a confirmation dialog before actually running the tool.

guitool.<name>.argprompt::
        Request a string argument from the user, and pass it to the tool
        through the 'ARGS' environment variable. Since requesting an
        argument implies confirmation, the 'confirm' option has no effect
        if this is enabled. If the option is set to 'true', 'yes', or '1',
        the dialog uses a built-in generic prompt; otherwise the exact
        value of the variable is used.

guitool.<name>.revprompt::
        Request a single valid revision from the user, and set the
        'REVISION' environment variable. In other aspects this option
        is similar to 'argprompt', and can be used together with it.

guitool.<name>.revunmerged::
        Show only unmerged branches in the 'revprompt' subdialog.
        This is useful for tools similar to merge or rebase, but not
        for things like checkout or reset.

guitool.<name>.title::
        Specifies the title to use for the prompt dialog. The default
        is the tool name.

guitool.<name>.prompt::
        Specifies the general prompt string to display at the top of
        the dialog, before subsections for 'argprompt' and 'revprompt'.
        The default value includes the actual command.

help.browser::
        Specify the browser that will be used to display help in the
        'web' format. See linkgit:git-help[1].

help.format::
        Override the default help format used by linkgit:git-help[1].
        Values 'man', 'info', 'web' and 'html' are supported. 'man' is
        the default. 'web' and 'html' are the same.

help.autocorrect::
        Automatically correct and execute mistyped commands after
        waiting for the given number of deciseconds (0.1 sec). If more
        than one command can be deduced from the entered text, nothing
        will be executed.  If the value of this option is negative,
        the corrected command will be executed immediately. If the
        value is 0 - the command will be just shown but not executed.
        This is the default.

help.htmlpath::
        Specify the path where the HTML documentation resides. File system paths
        and URLs are supported. HTML pages will be prefixed with this path when
        help is displayed in the 'web' format. This defaults to the documentation
        path of your Git installation.

http.proxy::
        Override the HTTP proxy, normally configured using the 'http_proxy',
        'https_proxy', and 'all_proxy' environment variables (see
        `curl(1)`).  This can be overridden on a per-remote basis; see
        remote.<name>.proxy

http.cookiefile::
        File containing previously stored cookie lines which should be used
        in the Git http session, if they match the server. The file format
        of the file to read cookies from should be plain HTTP headers or
        the Netscape/Mozilla cookie file format (see linkgit:curl[1]).
        NOTE that the file specified with http.cookiefile is only used as
        input unless http.saveCookies is set.

http.savecookies::
        If set, store cookies received during requests to the file specified by
        http.cookiefile. Has no effect if http.cookiefile is unset.

http.sslVerify::
        Whether to verify the SSL certificate when fetching or pushing
        over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
        variable.

http.sslCert::
        File containing the SSL certificate when fetching or pushing
        over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment
        variable.

http.sslKey::
        File containing the SSL private key when fetching or pushing
        over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
        variable.

http.sslCertPasswordProtected::
        Enable Git's password prompt for the SSL certificate.  Otherwise
        OpenSSL will prompt the user, possibly many times, if the
        certificate or private key is encrypted.  Can be overridden by the
        'GIT_SSL_CERT_PASSWORD_PROTECTED' environment variable.

http.sslCAInfo::
        File containing the certificates to verify the peer with when
        fetching or pushing over HTTPS. Can be overridden by the
        'GIT_SSL_CAINFO' environment variable.

http.sslCAPath::
        Path containing files with the CA certificates to verify the peer
        with when fetching or pushing over HTTPS. Can be overridden
        by the 'GIT_SSL_CAPATH' environment variable.

http.sslTry::
        Attempt to use AUTH SSL/TLS and encrypted data transfers
        when connecting via regular FTP protocol. This might be needed
        if the FTP server requires it for security reasons or you wish
        to connect securely whenever remote FTP server supports it.
        Default is false since it might trigger certificate verification
        errors on misconfigured servers.

http.maxRequests::
        How many HTTP requests to launch in parallel. Can be overridden
        by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.

http.minSessions::
        The number of curl sessions (counted across slots) to be kept across
        requests. They will not be ended with curl_easy_cleanup() until
        http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this
        value will be capped at 1. Defaults to 1.

http.postBuffer::
        Maximum size in bytes of the buffer used by smart HTTP
        transports when POSTing data to the remote system.
        For requests larger than this buffer size, HTTP/1.1 and
        Transfer-Encoding: chunked is used to avoid creating a
        massive pack file locally.  Default is 1 MiB, which is
        sufficient for most requests.

http.lowSpeedLimit, http.lowSpeedTime::
        If the HTTP transfer speed is less than 'http.lowSpeedLimit'
        for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
        Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
        'GIT_HTTP_LOW_SPEED_TIME' environment variables.

http.noEPSV::
        A boolean which disables using of EPSV ftp command by curl.
        This can helpful with some "poor" ftp servers which don't
        support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
        environment variable. Default is false (curl will use EPSV).

http.useragent::
        The HTTP USER_AGENT string presented to an HTTP server.  The default
        value represents the version of the client Git such as git/1.7.1.
        This option allows you to override this value to a more common value
        such as Mozilla/4.0.  This may be necessary, for instance, if
        connecting through a firewall that restricts HTTP connections to a set
        of common USER_AGENT strings (but not including those like git/1.7.1).
        Can be overridden by the 'GIT_HTTP_USER_AGENT' environment variable.

http.<url>.*::
        Any of the http.* options above can be applied selectively to some URLs.
        For a config key to match a URL, each element of the config key is
        compared to that of the URL, in the following order:
+
--
. Scheme (e.g., `https` in `https://example.com/`). This field
  must match exactly between the config key and the URL.

. Host/domain name (e.g., `example.com` in `https://example.com/`).
  This field must match exactly between the config key and the URL.

. Port number (e.g., `8080` in `http://example.com:8080/`).
  This field must match exactly between the config key and the URL.
  Omitted port numbers are automatically converted to the correct
  default for the scheme before matching.

. Path (e.g., `repo.git` in `https://example.com/repo.git`). The
  path field of the config key must match the path field of the URL
  either exactly or as a prefix of slash-delimited path elements.  This means
  a config key with path `foo/` matches URL path `foo/bar`.  A prefix can only
  match on a slash (`/`) boundary.  Longer matches take precedence (so a config
  key with path `foo/bar` is a better match to URL path `foo/bar` than a config
  key with just path `foo/`).

. User name (e.g., `user` in `https://user@example.com/repo.git`). If
  the config key has a user name it must match the user name in the
  URL exactly. If the config key does not have a user name, that
  config key will match a URL with any user name (including none),
  but at a lower precedence than a config key with a user name.
--
+
The list above is ordered by decreasing precedence; a URL that matches
a config key's path is preferred to one that matches its user name. For example,
if the URL is `https://user@example.com/foo/bar` a config key match of
`https://example.com/foo` will be preferred over a config key match of
`https://user@example.com`.
+
All URLs are normalized before attempting any matching (the password part,
if embedded in the URL, is always ignored for matching purposes) so that
equivalent URLs that are simply spelled differently will match properly.
Environment variable settings always override any matches.  The URLs that are
matched against are those given directly to Git commands.  This means any URLs
visited as a result of a redirection do not participate in matching.

i18n.commitEncoding::
        Character encoding the commit messages are stored in; Git itself
        does not care per se, but this information is necessary e.g. when
        importing commits from emails or in the gitk graphical history
        browser (and possibly at other places in the future or in other
        porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.

i18n.logOutputEncoding::
        Character encoding the commit messages are converted to when
        running 'git log' and friends.

imap::
        The configuration variables in the 'imap' section are described
        in linkgit:git-imap-send[1].

index.version::
        Specify the version with which new index files should be
        initialized.  This does not affect existing repositories.

init.templatedir::
        Specify the directory from which templates will be copied.
        (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].)

instaweb.browser::
        Specify the program that will be used to browse your working
        repository in gitweb. See linkgit:git-instaweb[1].

instaweb.httpd::
        The HTTP daemon command-line to start gitweb on your working
        repository. See linkgit:git-instaweb[1].

instaweb.local::
        If true the web server started by linkgit:git-instaweb[1] will
        be bound to the local IP (127.0.0.1).

instaweb.modulepath::
        The default module path for linkgit:git-instaweb[1] to use
        instead of /usr/lib/apache2/modules.  Only used if httpd
        is Apache.

instaweb.port::
        The port number to bind the gitweb httpd to. See
        linkgit:git-instaweb[1].

interactive.singlekey::
        In interactive commands, allow the user to provide one-letter
        input with a single key (i.e., without hitting enter).
        Currently this is used by the `--patch` mode of
        linkgit:git-add[1], linkgit:git-checkout[1], linkgit:git-commit[1],
        linkgit:git-reset[1], and linkgit:git-stash[1]. Note that this
        setting is silently ignored if portable keystroke input
        is not available; requires the Perl module Term::ReadKey.

log.abbrevCommit::
        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
        linkgit:git-whatchanged[1] assume `--abbrev-commit`. You may
        override this option with `--no-abbrev-commit`.

log.date::
        Set the default date-time mode for the 'log' command.
        Setting a value for log.date is similar to using 'git log''s
        `--date` option.  Possible values are `relative`, `local`,
        `default`, `iso`, `rfc`, and `short`; see linkgit:git-log[1]
        for details.

log.decorate::
        Print out the ref names of any commits that are shown by the log
        command. If 'short' is specified, the ref name prefixes 'refs/heads/',
        'refs/tags/' and 'refs/remotes/' will not be printed. If 'full' is
        specified, the full ref name (including prefix) will be printed.
        This is the same as the log commands '--decorate' option.

log.showroot::
        If true, the initial commit will be shown as a big creation event.
        This is equivalent to a diff against an empty tree.
        Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
        normally hide the root commit will now show it. True by default.

log.mailmap::
        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
        linkgit:git-whatchanged[1] assume `--use-mailmap`.

mailmap.file::
        The location of an augmenting mailmap file. The default
        mailmap, located in the root of the repository, is loaded
        first, then the mailmap file pointed to by this variable.
        The location of the mailmap file may be in a repository
        subdirectory, or somewhere outside of the repository itself.
        See linkgit:git-shortlog[1] and linkgit:git-blame[1].

mailmap.blob::
        Like `mailmap.file`, but consider the value as a reference to a
        blob in the repository. If both `mailmap.file` and
        `mailmap.blob` are given, both are parsed, with entries from
        `mailmap.file` taking precedence. In a bare repository, this
        defaults to `HEAD:.mailmap`. In a non-bare repository, it
        defaults to empty.

man.viewer::
        Specify the programs that may be used to display help in the
        'man' format. See linkgit:git-help[1].

man.<tool>.cmd::
        Specify the command to invoke the specified man viewer. The
        specified command is evaluated in shell with the man page
        passed as argument. (See linkgit:git-help[1].)

man.<tool>.path::
        Override the path for the given tool that may be used to
        display help in the 'man' format. See linkgit:git-help[1].

include::merge-config.txt[]

mergetool.<tool>.path::
        Override the path for the given tool.  This is useful in case
        your tool is not in the PATH.

mergetool.<tool>.cmd::
        Specify the command to invoke the specified merge tool.  The
        specified command is evaluated in shell with the following
        variables available: 'BASE' is the name of a temporary file
        containing the common base of the files to be merged, if available;
        'LOCAL' is the name of a temporary file containing the contents of
        the file on the current branch; 'REMOTE' is the name of a temporary
        file containing the contents of the file from the branch being
        merged; 'MERGED' contains the name of the file to which the merge
        tool should write the results of a successful merge.

mergetool.<tool>.trustExitCode::
        For a custom merge command, specify whether the exit code of
        the merge command can be used to determine whether the merge was
        successful.  If this is not set to true then the merge target file
        timestamp is checked and the merge assumed to have been successful
        if the file has been updated, otherwise the user is prompted to
        indicate the success of the merge.

mergetool.meld.hasOutput::
        Older versions of `meld` do not support the `--output` option.
        Git will attempt to detect whether `meld` supports `--output`
        by inspecting the output of `meld --help`.  Configuring
        `mergetool.meld.hasOutput` will make Git skip these checks and
        use the configured value instead.  Setting `mergetool.meld.hasOutput`
        to `true` tells Git to unconditionally use the `--output` option,
        and `false` avoids using `--output`.

mergetool.keepBackup::
        After performing a merge, the original file with conflict markers
        can be saved as a file with a `.orig` extension.  If this variable
        is set to `false` then this file is not preserved.  Defaults to
        `true` (i.e. keep the backup files).

mergetool.keepTemporaries::
        When invoking a custom merge tool, Git uses a set of temporary
        files to pass to the tool. If the tool returns an error and this
        variable is set to `true`, then these temporary files will be
        preserved, otherwise they will be removed after the tool has
        exited. Defaults to `false`.

mergetool.writeToTemp::
        Git writes temporary 'BASE', 'LOCAL', and 'REMOTE' versions of
        conflicting files in the worktree by default.  Git will attempt
        to use a temporary directory for these files when set `true`.
        Defaults to `false`.

mergetool.prompt::
        Prompt before each invocation of the merge resolution program.

notes.displayRef::
        The (fully qualified) refname from which to show notes when
        showing commit messages.  The value of this variable can be set
        to a glob, in which case notes from all matching refs will be
        shown.  You may also specify this configuration variable
        several times.  A warning will be issued for refs that do not
        exist, but a glob that does not match any refs is silently
        ignored.
+
This setting can be overridden with the `GIT_NOTES_DISPLAY_REF`
environment variable, which must be a colon separated list of refs or
globs.
+
The effective value of "core.notesRef" (possibly overridden by
GIT_NOTES_REF) is also implicitly added to the list of refs to be
displayed.

notes.rewrite.<command>::
        When rewriting commits with <command> (currently `amend` or
        `rebase`) and this variable is set to `true`, Git
        automatically copies your notes from the original to the
        rewritten commit.  Defaults to `true`, but see
        "notes.rewriteRef" below.

notes.rewriteMode::
        When copying notes during a rewrite (see the
        "notes.rewrite.<command>" option), determines what to do if
        the target commit already has a note.  Must be one of
        `overwrite`, `concatenate`, or `ignore`.  Defaults to
        `concatenate`.
+
This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
environment variable.

notes.rewriteRef::
        When copying notes during a rewrite, specifies the (fully
        qualified) ref whose notes should be copied.  The ref may be a
        glob, in which case notes in all matching refs will be copied.
        You may also specify this configuration several times.
+
Does not have a default value; you must configure this variable to
enable note rewriting.  Set it to `refs/notes/commits` to enable
rewriting for the default commit notes.
+
This setting can be overridden with the `GIT_NOTES_REWRITE_REF`
environment variable, which must be a colon separated list of refs or
globs.

pack.window::
        The size of the window used by linkgit:git-pack-objects[1] when no
        window size is given on the command line. Defaults to 10.

pack.depth::
        The maximum delta depth used by linkgit:git-pack-objects[1] when no
        maximum depth is given on the command line. Defaults to 50.

pack.windowMemory::
        The maximum size of memory that is consumed by each thread
        in linkgit:git-pack-objects[1] for pack window memory when
        no limit is given on the command line.  The value can be
        suffixed with "k", "m", or "g".  When left unconfigured (or
        set explicitly to 0), there will be no limit.

pack.compression::
        An integer -1..9, indicating the compression level for objects
        in a pack file. -1 is the zlib default. 0 means no
        compression, and 1..9 are various speed/size tradeoffs, 9 being
        slowest.  If not set,  defaults to core.compression.  If that is
        not set,  defaults to -1, the zlib default, which is "a default
        compromise between speed and compression (currently equivalent
        to level 6)."
+
Note that changing the compression level will not automatically recompress
all existing objects. You can force recompression by passing the -F option
to linkgit:git-repack[1].

pack.deltaCacheSize::
        The maximum memory in bytes used for caching deltas in
        linkgit:git-pack-objects[1] before writing them out to a pack.
        This cache is used to speed up the writing object phase by not
        having to recompute the final delta result once the best match
        for all objects is found.  Repacking large repositories on machines
        which are tight with memory might be badly impacted by this though,
        especially if this cache pushes the system into swapping.
        A value of 0 means no limit. The smallest size of 1 byte may be
        used to virtually disable this cache. Defaults to 256 MiB.

pack.deltaCacheLimit::
        The maximum size of a delta, that is cached in
        linkgit:git-pack-objects[1]. This cache is used to speed up the
        writing object phase by not having to recompute the final delta
        result once the best match for all objects is found. Defaults to 1000.

pack.threads::
        Specifies the number of threads to spawn when searching for best
        delta matches.  This requires that linkgit:git-pack-objects[1]
        be compiled with pthreads otherwise this option is ignored with a
        warning. This is meant to reduce packing time on multiprocessor
        machines. The required amount of memory for the delta search window
        is however multiplied by the number of threads.
        Specifying 0 will cause Git to auto-detect the number of CPU's
        and set the number of threads accordingly.

pack.indexVersion::
        Specify the default pack index version.  Valid values are 1 for
        legacy pack index used by Git versions prior to 1.5.2, and 2 for
        the new pack index with capabilities for packs larger than 4 GB
        as well as proper protection against the repacking of corrupted
        packs.  Version 2 is the default.  Note that version 2 is enforced
        and this config option ignored whenever the corresponding pack is
        larger than 2 GB.
+
If you have an old Git that does not understand the version 2 `*.idx` file,
cloning or fetching over a non native protocol (e.g. "http" and "rsync")
that will copy both `*.pack` file and corresponding `*.idx` file from the
other side may give you a repository that cannot be accessed with your
older version of Git. If the `*.pack` file is smaller than 2 GB, however,
you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
the `*.idx` file.

pack.packSizeLimit::
        The maximum size of a pack.  This setting only affects
        packing to a file when repacking, i.e. the git:// protocol
        is unaffected.  It can be overridden by the `--max-pack-size`
        option of linkgit:git-repack[1]. The minimum size allowed is
        limited to 1 MiB. The default is unlimited.
        Common unit suffixes of 'k', 'm', or 'g' are
        supported.

pack.useBitmaps::
        When true, git will use pack bitmaps (if available) when packing
        to stdout (e.g., during the server side of a fetch). Defaults to
        true. You should not generally need to turn this off unless
        you are debugging pack bitmaps.

pack.writebitmaps (deprecated)::
        This is a deprecated synonym for `repack.writeBitmaps`.

pack.writeBitmapHashCache::
        When true, git will include a "hash cache" section in the bitmap
        index (if one is written). This cache can be used to feed git's
        delta heuristics, potentially leading to better deltas between
        bitmapped and non-bitmapped objects (e.g., when serving a fetch
        between an older, bitmapped pack and objects that have been
        pushed since the last gc). The downside is that it consumes 4
        bytes per object of disk space, and that JGit's bitmap
        implementation does not understand it, causing it to complain if
        Git and JGit are used on the same repository. Defaults to false.

pager.<cmd>::
        If the value is boolean, turns on or off pagination of the
        output of a particular Git subcommand when writing to a tty.
        Otherwise, turns on pagination for the subcommand using the
        pager specified by the value of `pager.<cmd>`.  If `--paginate`
        or `--no-pager` is specified on the command line, it takes
        precedence over this option.  To disable pagination for all
        commands, set `core.pager` or `GIT_PAGER` to `cat`.

pretty.<name>::
        Alias for a --pretty= format string, as specified in
        linkgit:git-log[1]. Any aliases defined here can be used just
        as the built-in pretty formats could. For example,
        running `git config pretty.changelog "format:* %H %s"`
        would cause the invocation `git log --pretty=changelog`
        to be equivalent to running `git log "--pretty=format:* %H %s"`.
        Note that an alias with the same name as a built-in format
        will be silently ignored.

pull.ff::
        By default, Git does not create an extra merge commit when merging
        a commit that is a descendant of the current commit. Instead, the
        tip of the current branch is fast-forwarded. When set to `false`,
        this variable tells Git to create an extra merge commit in such
        a case (equivalent to giving the `--no-ff` option from the command
        line). When set to `only`, only such fast-forward merges are
        allowed (equivalent to giving the `--ff-only` option from the
        command line).

pull.rebase::
        When true, rebase branches on top of the fetched branch, instead
        of merging the default branch from the default remote when "git
        pull" is run. See "branch.<name>.rebase" for setting this on a
        per-branch basis.
+
        When preserve, also pass `--preserve-merges` along to 'git rebase'
        so that locally committed merge commits will not be flattened
        by running 'git pull'.
+
*NOTE*: this is a possibly dangerous operation; do *not* use
it unless you understand the implications (see linkgit:git-rebase[1]
for details).

pull.octopus::
        The default merge strategy to use when pulling multiple branches
        at once.

pull.twohead::
        The default merge strategy to use when pulling a single branch.

push.default::
        Defines the action `git push` should take if no refspec is
        explicitly given.  Different values are well-suited for
        specific workflows; for instance, in a purely central workflow
        (i.e. the fetch source is equal to the push destination),
        `upstream` is probably what you want.  Possible values are:
+
--

* `nothing` - do not push anything (error out) unless a refspec is
  explicitly given. This is primarily meant for people who want to
  avoid mistakes by always being explicit.

* `current` - push the current branch to update a branch with the same
  name on the receiving end.  Works in both central and non-central
  workflows.

* `upstream` - push the current branch back to the branch whose
  changes are usually integrated into the current branch (which is
  called `@{upstream}`).  This mode only makes sense if you are
  pushing to the same repository you would normally pull from
  (i.e. central workflow).

* `simple` - in centralized workflow, work like `upstream` with an
  added safety to refuse to push if the upstream branch's name is
  different from the local one.
+
When pushing to a remote that is different from the remote you normally
pull from, work as `current`.  This is the safest option and is suited
for beginners.
+
This mode has become the default in Git 2.0.

* `matching` - push all branches having the same name on both ends.
  This makes the repository you are pushing to remember the set of
  branches that will be pushed out (e.g. if you always push 'maint'
  and 'master' there and no other branches, the repository you push
  to will have these two branches, and your local 'maint' and
  'master' will be pushed there).
+
To use this mode effectively, you have to make sure _all_ the
branches you would push out are ready to be pushed out before
running 'git push', as the whole point of this mode is to allow you
to push all of the branches in one go.  If you usually finish work
on only one branch and push out the result, while other branches are
unfinished, this mode is not for you.  Also this mode is not
suitable for pushing into a shared central repository, as other
people may add new branches there, or update the tip of existing
branches outside your control.
+
This used to be the default, but not since Git 2.0 (`simple` is the
new default).

--

rebase.stat::
        Whether to show a diffstat of what changed upstream since the last
        rebase. False by default.

rebase.autosquash::
        If set to true enable '--autosquash' option by default.

rebase.autostash::
        When set to true, automatically create a temporary stash
        before the operation begins, and apply it after the operation
        ends.  This means that you can run rebase on a dirty worktree.
        However, use with care: the final stash application after a
        successful rebase might result in non-trivial conflicts.
        Defaults to false.

receive.advertiseatomic::
        By default, git-receive-pack will advertise the atomic push
        capability to its clients. If you don't want to this capability
        to be advertised, set this variable to false.

receive.autogc::
        By default, git-receive-pack will run "git-gc --auto" after
        receiving data from git-push and updating refs.  You can stop
        it by setting this variable to false.

receive.certnonceseed::
        By setting this variable to a string, `git receive-pack`
        will accept a `git push --signed` and verifies it by using
        a "nonce" protected by HMAC using this string as a secret
        key.

receive.certnonceslop::
        When a `git push --signed` sent a push certificate with a
        "nonce" that was issued by a receive-pack serving the same
        repository within this many seconds, export the "nonce"
        found in the certificate to `GIT_PUSH_CERT_NONCE` to the
        hooks (instead of what the receive-pack asked the sending
        side to include).  This may allow writing checks in
        `pre-receive` and `post-receive` a bit easier.  Instead of
        checking `GIT_PUSH_CERT_NONCE_SLOP` environment variable
        that records by how many seconds the nonce is stale to
        decide if they want to accept the certificate, they only
        can check `GIT_PUSH_CERT_NONCE_STATUS` is `OK`.

receive.fsckObjects::
        If it is set to true, git-receive-pack will check all received
        objects. It will abort in the case of a malformed object or a
        broken link. The result of an abort are only dangling objects.
        Defaults to false. If not set, the value of `transfer.fsckObjects`
        is used instead.

receive.unpackLimit::
        If the number of objects received in a push is below this
        limit then the objects will be unpacked into loose object
        files. However if the number of received objects equals or
        exceeds this limit then the received pack will be stored as
        a pack, after adding any missing delta bases.  Storing the
        pack from a push can make the push operation complete faster,
        especially on slow filesystems.  If not set, the value of
        `transfer.unpackLimit` is used instead.

receive.denyDeletes::
        If set to true, git-receive-pack will deny a ref update that deletes
        the ref. Use this to prevent such a ref deletion via a push.

receive.denyDeleteCurrent::
        If set to true, git-receive-pack will deny a ref update that
        deletes the currently checked out branch of a non-bare repository.

receive.denyCurrentBranch::
        If set to true or "refuse", git-receive-pack will deny a ref update
        to the currently checked out branch of a non-bare repository.
        Such a push is potentially dangerous because it brings the HEAD
        out of sync with the index and working tree. If set to "warn",
        print a warning of such a push to stderr, but allow the push to
        proceed. If set to false or "ignore", allow such pushes with no
        message. Defaults to "refuse".
+
Another option is "updateInstead" which will update the working
tree if pushing into the current branch.  This option is
intended for synchronizing working directories when one side is not easily
accessible via interactive ssh (e.g. a live web site, hence the requirement
that the working directory be clean). This mode also comes in handy when
developing inside a VM to test and fix code on different Operating Systems.
+
By default, "updateInstead" will refuse the push if the working tree or
the index have any difference from the HEAD, but the `push-to-checkout`
hook can be used to customize this.  See linkgit:githooks[5].

receive.denyNonFastForwards::
        If set to true, git-receive-pack will deny a ref update which is
        not a fast-forward. Use this to prevent such an update via a push,
        even if that push is forced. This configuration variable is
        set when initializing a shared repository.

receive.hiderefs::
        String(s) `receive-pack` uses to decide which refs to omit
        from its initial advertisement.  Use more than one
        definitions to specify multiple prefix strings. A ref that
        are under the hierarchies listed on the value of this
        variable is excluded, and is hidden when responding to `git
        push`, and an attempt to update or delete a hidden ref by
        `git push` is rejected.

receive.updateserverinfo::
        If set to true, git-receive-pack will run git-update-server-info
        after receiving data from git-push and updating refs.

receive.shallowupdate::
        If set to true, .git/shallow can be updated when new refs
        require new shallow roots. Otherwise those refs are rejected.

remote.pushdefault::
        The remote to push to by default.  Overrides
        `branch.<name>.remote` for all branches, and is overridden by
        `branch.<name>.pushremote` for specific branches.

remote.<name>.url::
        The URL of a remote repository.  See linkgit:git-fetch[1] or
        linkgit:git-push[1].

remote.<name>.pushurl::
        The push URL of a remote repository.  See linkgit:git-push[1].

remote.<name>.proxy::
        For remotes that require curl (http, https and ftp), the URL to
        the proxy to use for that remote.  Set to the empty string to
        disable proxying for that remote.

remote.<name>.fetch::
        The default set of "refspec" for linkgit:git-fetch[1]. See
        linkgit:git-fetch[1].

remote.<name>.push::
        The default set of "refspec" for linkgit:git-push[1]. See
        linkgit:git-push[1].

remote.<name>.mirror::
        If true, pushing to this remote will automatically behave
        as if the `--mirror` option was given on the command line.

remote.<name>.skipDefaultUpdate::
        If true, this remote will be skipped by default when updating
        using linkgit:git-fetch[1] or the `update` subcommand of
        linkgit:git-remote[1].

remote.<name>.skipFetchAll::
        If true, this remote will be skipped by default when updating
        using linkgit:git-fetch[1] or the `update` subcommand of
        linkgit:git-remote[1].

remote.<name>.receivepack::
        The default program to execute on the remote side when pushing.  See
        option \--receive-pack of linkgit:git-push[1].

remote.<name>.uploadpack::
        The default program to execute on the remote side when fetching.  See
        option \--upload-pack of linkgit:git-fetch-pack[1].

remote.<name>.tagopt::
        Setting this value to \--no-tags disables automatic tag following when
        fetching from remote <name>. Setting it to \--tags will fetch every
        tag from remote <name>, even if they are not reachable from remote
        branch heads. Passing these flags directly to linkgit:git-fetch[1] can
        override this setting. See options \--tags and \--no-tags of
        linkgit:git-fetch[1].

remote.<name>.vcs::
        Setting this to a value <vcs> will cause Git to interact with
        the remote with the git-remote-<vcs> helper.

remote.<name>.prune::
        When set to true, fetching from this remote by default will also
        remove any remote-tracking references that no longer exist on the
        remote (as if the `--prune` option was given on the command line).
        Overrides `fetch.prune` settings, if any.

remotes.<group>::
        The list of remotes which are fetched by "git remote update
        <group>".  See linkgit:git-remote[1].

repack.usedeltabaseoffset::
        By default, linkgit:git-repack[1] creates packs that use
        delta-base offset. If you need to share your repository with
        Git older than version 1.4.4, either directly or via a dumb
        protocol such as http, then you need to set this option to
        "false" and repack. Access from old Git versions over the
        native protocol are unaffected by this option.

repack.packKeptObjects::
        If set to true, makes `git repack` act as if
        `--pack-kept-objects` was passed. See linkgit:git-repack[1] for
        details. Defaults to `false` normally, but `true` if a bitmap
        index is being written (either via `--write-bitmap-index` or
        `repack.writeBitmaps`).

repack.writeBitmaps::
        When true, git will write a bitmap index when packing all
        objects to disk (e.g., when `git repack -a` is run).  This
        index can speed up the "counting objects" phase of subsequent
        packs created for clones and fetches, at the cost of some disk
        space and extra time spent on the initial repack.  Defaults to
        false.

rerere.autoupdate::
        When set to true, `git-rerere` updates the index with the
        resulting contents after it cleanly resolves conflicts using
        previously recorded resolution.  Defaults to false.

rerere.enabled::
        Activate recording of resolved conflicts, so that identical
        conflict hunks can be resolved automatically, should they be
        encountered again.  By default, linkgit:git-rerere[1] is
        enabled if there is an `rr-cache` directory under the
        `$GIT_DIR`, e.g. if "rerere" was previously used in the
        repository.

sendemail.identity::
        A configuration identity. When given, causes values in the
        'sendemail.<identity>' subsection to take precedence over
        values in the 'sendemail' section. The default identity is
        the value of 'sendemail.identity'.

sendemail.smtpencryption::
        See linkgit:git-send-email[1] for description.  Note that this
        setting is not subject to the 'identity' mechanism.

sendemail.smtpssl (deprecated)::
        Deprecated alias for 'sendemail.smtpencryption = ssl'.

sendemail.smtpsslcertpath::
        Path to ca-certificates (either a directory or a single file).
        Set it to an empty string to disable certificate verification.

sendemail.<identity>.*::
        Identity-specific versions of the 'sendemail.*' parameters
        found below, taking precedence over those when the this
        identity is selected, through command-line or
        'sendemail.identity'.

sendemail.signedoffcc (deprecated)::
        Deprecated alias for 'sendemail.signedoffbycc'.

showbranch.default::
        The default set of branches for linkgit:git-show-branch[1].
        See linkgit:git-show-branch[1].

status.relativePaths::
        By default, linkgit:git-status[1] shows paths relative to the
        current directory. Setting this variable to `false` shows paths
        relative to the repository root (this was the default for Git
        prior to v1.5.4).

status.short::
        Set to true to enable --short by default in linkgit:git-status[1].
        The option --no-short takes precedence over this variable.

status.branch::
        Set to true to enable --branch by default in linkgit:git-status[1].
        The option --no-branch takes precedence over this variable.

status.displayCommentPrefix::
        If set to true, linkgit:git-status[1] will insert a comment
        prefix before each output line (starting with
        `core.commentChar`, i.e. `#` by default). This was the
        behavior of linkgit:git-status[1] in Git 1.8.4 and previous.
        Defaults to false.

status.showUntrackedFiles::
        By default, linkgit:git-status[1] and linkgit:git-commit[1] show
        files which are not currently tracked by Git. Directories which
        contain only untracked files, are shown with the directory name
        only. Showing untracked files means that Git needs to lstat() all
        the files in the whole repository, which might be slow on some
        systems. So, this variable controls how the commands displays
        the untracked files. Possible values are:
+
--
* `no` - Show no untracked files.
* `normal` - Show untracked files and directories.
* `all` - Show also individual files in untracked directories.
--
+
If this variable is not specified, it defaults to 'normal'.
This variable can be overridden with the -u|--untracked-files option
of linkgit:git-status[1] and linkgit:git-commit[1].

status.submodulesummary::
        Defaults to false.
        If this is set to a non zero number or true (identical to -1 or an
        unlimited number), the submodule summary will be enabled and a
        summary of commits for modified submodules will be shown (see
        --summary-limit option of linkgit:git-submodule[1]). Please note
        that the summary output command will be suppressed for all
        submodules when `diff.ignoreSubmodules` is set to 'all' or only
        for those submodules where `submodule.<name>.ignore=all`. The only
        exception to that rule is that status and commit will show staged
        submodule changes. To
        also view the summary for ignored submodules you can either use
        the --ignore-submodules=dirty command-line option or the 'git
        submodule summary' command, which shows a similar output but does
        not honor these settings.

submodule.<name>.path::
submodule.<name>.url::
submodule.<name>.update::
        The path within this project, URL, and the updating strategy
        for a submodule.  These variables are initially populated
        by 'git submodule init'; edit them to override the
        URL and other values found in the `.gitmodules` file.  See
        linkgit:git-submodule[1] and linkgit:gitmodules[5] for details.

submodule.<name>.branch::
        The remote branch name for a submodule, used by `git submodule
        update --remote`.  Set this option to override the value found in
        the `.gitmodules` file.  See linkgit:git-submodule[1] and
        linkgit:gitmodules[5] for details.

submodule.<name>.fetchRecurseSubmodules::
        This option can be used to control recursive fetching of this
        submodule. It can be overridden by using the --[no-]recurse-submodules
        command-line option to "git fetch" and "git pull".
        This setting will override that from in the linkgit:gitmodules[5]
        file.

submodule.<name>.ignore::
        Defines under what circumstances "git status" and the diff family show
        a submodule as modified. When set to "all", it will never be considered
        modified (but it will nonetheless show up in the output of status and
        commit when it has been staged), "dirty" will ignore all changes
        to the submodules work tree and
        takes only differences between the HEAD of the submodule and the commit
        recorded in the superproject into account. "untracked" will additionally
        let submodules with modified tracked files in their work tree show up.
        Using "none" (the default when this option is not set) also shows
        submodules that have untracked files in their work tree as changed.
        This setting overrides any setting made in .gitmodules for this submodule,
        both settings can be overridden on the command line by using the
        "--ignore-submodules" option. The 'git submodule' commands are not
        affected by this setting.

tag.sort::
        This variable controls the sort ordering of tags when displayed by
        linkgit:git-tag[1]. Without the "--sort=<value>" option provided, the
        value of this variable will be used as the default.

tar.umask::
        This variable can be used to restrict the permission bits of
        tar archive entries.  The default is 0002, which turns off the
        world write bit.  The special value "user" indicates that the
        archiving user's umask will be used instead.  See umask(2) and
        linkgit:git-archive[1].

transfer.fsckObjects::
        When `fetch.fsckObjects` or `receive.fsckObjects` are
        not set, the value of this variable is used instead.
        Defaults to false.

transfer.hiderefs::
        This variable can be used to set both `receive.hiderefs`
        and `uploadpack.hiderefs` at the same time to the same
        values.  See entries for these other variables.

transfer.unpackLimit::
        When `fetch.unpackLimit` or `receive.unpackLimit` are
        not set, the value of this variable is used instead.
        The default value is 100.

uploadarchive.allowUnreachable::
        If true, allow clients to use `git archive --remote` to request
        any tree, whether reachable from the ref tips or not. See the
        discussion in the `SECURITY` section of
        linkgit:git-upload-archive[1] for more details. Defaults to
        `false`.

uploadpack.hiderefs::
        String(s) `upload-pack` uses to decide which refs to omit
        from its initial advertisement.  Use more than one
        definitions to specify multiple prefix strings. A ref that
        are under the hierarchies listed on the value of this
        variable is excluded, and is hidden from `git ls-remote`,
        `git fetch`, etc.  An attempt to fetch a hidden ref by `git
        fetch` will fail.  See also `uploadpack.allowtipsha1inwant`.

uploadpack.allowtipsha1inwant::
        When `uploadpack.hiderefs` is in effect, allow `upload-pack`
        to accept a fetch request that asks for an object at the tip
        of a hidden ref (by default, such a request is rejected).
        see also `uploadpack.hiderefs`.

uploadpack.keepalive::
        When `upload-pack` has started `pack-objects`, there may be a
        quiet period while `pack-objects` prepares the pack. Normally
        it would output progress information, but if `--quiet` was used
        for the fetch, `pack-objects` will output nothing at all until
        the pack data begins. Some clients and networks may consider
        the server to be hung and give up. Setting this option instructs
        `upload-pack` to send an empty keepalive packet every
        `uploadpack.keepalive` seconds. Setting this option to 0
        disables keepalive packets entirely. The default is 5 seconds.

url.<base>.insteadOf::
        Any URL that starts with this value will be rewritten to
        start, instead, with <base>. In cases where some site serves a
        large number of repositories, and serves them with multiple
        access methods, and some users need to use different access
        methods, this feature allows people to specify any of the
        equivalent URLs and have Git automatically rewrite the URL to
        the best alternative for the particular user, even for a
        never-before-seen repository on the site.  When more than one
        insteadOf strings match a given URL, the longest match is used.

url.<base>.pushInsteadOf::
        Any URL that starts with this value will not be pushed to;
        instead, it will be rewritten to start with <base>, and the
        resulting URL will be pushed to. In cases where some site serves
        a large number of repositories, and serves them with multiple
        access methods, some of which do not allow push, this feature
        allows people to specify a pull-only URL and have Git
        automatically use an appropriate URL to push, even for a
        never-before-seen repository on the site.  When more than one
        pushInsteadOf strings match a given URL, the longest match is
        used.  If a remote has an explicit pushurl, Git will ignore this
        setting for that remote.

user.email::
        Your email address to be recorded in any newly created commits.
        Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
        'EMAIL' environment variables.  See linkgit:git-commit-tree[1].

user.name::
        Your full name to be recorded in any newly created commits.
        Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
        environment variables.  See linkgit:git-commit-tree[1].

user.signingkey::
        If linkgit:git-tag[1] or linkgit:git-commit[1] is not selecting the
        key you want it to automatically when creating a signed tag or
        commit, you can override the default selection with this variable.
        This option is passed unchanged to gpg's --local-user parameter,
        so you may specify a key using any method that gpg supports.

web.browser::
        Specify a web browser that may be used by some commands.
        Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
        may use it.
