20 Git is a fast, scalable, distributed revision control system with an
21 unusually rich command set that provides both high-level operations
22 and full access to internals.
24 See linkgit:gittutorial[7] to get started, then see
25 linkgit:giteveryday[7] for a useful minimum set of
26 commands. The link:user-manual.html[Git User's Manual] has a more
27 in-depth introduction.
29 After you mastered the basic concepts, you can come back to this
30 page to learn what commands Git offers. You can learn more about
31 individual Git commands with "git help command". linkgit:gitcli[7]
32 manual page gives you an overview of the command-line command syntax.
34 Formatted and hyperlinked version of the latest Git documentation
35 can be viewed at `http://git-htmldocs.googlecode.com/git/git.html`.
41 You are reading the documentation for the latest (possibly
42 unreleased) version of Git, that is available from the 'master'
43 branch of the `git.git` repository.

454 Prints the Git suite version that the 'git' program came from.
457 Prints the synopsis and a list of the most commonly used
458 commands. If the option '--all' or '-a' is given then all
459 available commands are printed. If a Git command is named this
460 option will bring up the manual page for that command.
462 Other options are available to control how the manual page is
463 displayed. See linkgit:git-help[1] for more information,
464 because `git --help ...` is converted internally into `git
468 Run as if git was started in '<path>' instead of the current working
469 directory. When multiple `-C` options are given, each subsequent
470 non-absolute `-C <path>` is interpreted relative to the preceding `-C
473 This option affects options that expect path name like `--git-dir` and
474 `--work-tree` in that their interpretations of the path names would be
475 made relative to the working directory caused by the `-C` option. For
476 example the following invocations are equivalent:
478 git --git-dir=a.git --work-tree=b -C c status
479 git --git-dir=c/a.git --work-tree=c/b status
482 Pass a configuration parameter to the command. The value
483 given will override values from configuration files.
484 The <name> is expected in the same format as listed by
485 'git config' (subkeys separated by dots).
487 Note that omitting the `=` in `git -c foo.bar ...` is allowed and sets
488 `foo.bar` to the boolean true value (just like `[foo]bar` would in a
489 config file). Including the equals but with an empty value (like `git -c
490 foo.bar= ...`) sets `foo.bar` to the empty string.
492 --exec-path[=<path>]::
493 Path to wherever your core Git programs are installed.
494 This can also be controlled by setting the GIT_EXEC_PATH
495 environment variable. If no path is given, 'git' will print
496 the current setting and then exit.
499 Print the path, without trailing slash, where Git's HTML
500 documentation is installed and exit.
503 Print the manpath (see `man(1)`) for the man pages for
504 this version of Git and exit.
507 Print the path where the Info files documenting this
508 version of Git are installed and exit.
512 Pipe all output into 'less' (or if set, $PAGER) if standard
513 output is a terminal. This overrides the `pager.<cmd>`
514 configuration options (see the "Configuration Mechanism" section
518 Do not pipe Git output into a pager.
521 Set the path to the repository. This can also be controlled by
522 setting the GIT_DIR environment variable. It can be an absolute
523 path or relative path to current working directory.
526 Set the path to the working tree. It can be an absolute path
527 or a path relative to the current working directory.
528 This can also be controlled by setting the GIT_WORK_TREE
529 environment variable and the core.worktree configuration
530 variable (see core.worktree in linkgit:git-config[1] for a
531 more detailed discussion).
534 Set the Git namespace. See linkgit:gitnamespaces[7] for more
535 details. Equivalent to setting the `GIT_NAMESPACE` environment
539 Treat the repository as a bare repository. If GIT_DIR
540 environment is not set, it is set to the current working
543 --no-replace-objects::
544 Do not use replacement refs to replace Git objects. See
545 linkgit:git-replace[1] for more information.
547 --literal-pathspecs::
548 Treat pathspecs literally (i.e. no globbing, no pathspec magic).
549 This is equivalent to setting the `GIT_LITERAL_PATHSPECS` environment
553 Add "glob" magic to all pathspec. This is equivalent to setting
554 the `GIT_GLOB_PATHSPECS` environment variable to `1`. Disabling
555 globbing on individual pathspecs can be done using pathspec
559 Add "literal" magic to all pathspec. This is equivalent to setting
560 the `GIT_NOGLOB_PATHSPECS` environment variable to `1`. Enabling
561 globbing on individual pathspecs can be done using pathspec
565 Add "icase" magic to all pathspec. This is equivalent to setting
566 the `GIT_ICASE_PATHSPECS` environment variable to `1`.
571 We divide Git into high level ("porcelain") commands and low level
572 ("plumbing") commands.
574 High-level commands (porcelain)
575 -------------------------------
577 We separate the porcelain commands into the main commands and some
578 ancillary user utilities.
580 Main porcelain commands
581 ~~~~~~~~~~~~~~~~~~~~~~~
583 include::cmds-mainporcelain.txt[]
589 include::cmds-ancillarymanipulators.txt[]
593 include::cmds-ancillaryinterrogators.txt[]
596 Interacting with Others
597 ~~~~~~~~~~~~~~~~~~~~~~~
599 These commands are to interact with foreign SCM and with other
600 people via patch over e-mail.
602 include::cmds-foreignscminterface.txt[]
605 Low-level commands (plumbing)
606 -----------------------------
608 Although Git includes its
609 own porcelain layer, its low-level commands are sufficient to support
610 development of alternative porcelains. Developers of such porcelains
611 might start by reading about linkgit:git-update-index[1] and
612 linkgit:git-read-tree[1].
614 The interface (input, output, set of options and the semantics)
615 to these low-level commands are meant to be a lot more stable
616 than Porcelain level commands, because these commands are
617 primarily for scripted use. The interface to Porcelain commands
618 on the other hand are subject to change in order to improve the
621 The following description divides
622 the low-level commands into commands that manipulate objects (in
623 the repository, index, and working tree), commands that interrogate and
624 compare objects, and commands that move objects and references between
628 Manipulation commands
629 ~~~~~~~~~~~~~~~~~~~~~
631 include::cmds-plumbingmanipulators.txt[]
634 Interrogation commands
635 ~~~~~~~~~~~~~~~~~~~~~~
637 include::cmds-plumbinginterrogators.txt[]
639 In general, the interrogate commands do not touch the files in
643 Synching repositories
644 ~~~~~~~~~~~~~~~~~~~~~
646 include::cmds-synchingrepositories.txt[]
648 The following are helper commands used by the above; end users
649 typically do not use them directly.
651 include::cmds-synchelpers.txt[]
654 Internal helper commands
655 ~~~~~~~~~~~~~~~~~~~~~~~~
657 These are internal helper commands used by other commands; end
658 users typically do not use them directly.
660 include::cmds-purehelpers.txt[]
663 Configuration Mechanism
664 -----------------------
666 Git uses a simple text format to store customizations that are per
667 repository and are per user. Such a configuration file may look
672 # A '#' or ';' character indicates a comment.
677 ; Don't trust file modes
682 name = "Junio C Hamano"
683 email = "gitster@pobox.com"
687 Various commands read from the configuration file and adjust
688 their operation accordingly. See linkgit:git-config[1] for a
689 list and more details about the configuration mechanism.
692 Identifier Terminology
693 ----------------------
695 Indicates the object name for any type of object.
698 Indicates a blob object name.
701 Indicates a tree object name.
704 Indicates a commit object name.
707 Indicates a tree, commit or tag object name. A
708 command that takes a <tree-ish> argument ultimately wants to
709 operate on a <tree> object but automatically dereferences
710 <commit> and <tag> objects that point at a <tree>.
713 Indicates a commit or tag object name. A
714 command that takes a <commit-ish> argument ultimately wants to
715 operate on a <commit> object but automatically dereferences
716 <tag> objects that point at a <commit>.
719 Indicates that an object type is required.
720 Currently one of: `blob`, `tree`, `commit`, or `tag`.
723 Indicates a filename - almost always relative to the
724 root of the tree structure `GIT_INDEX_FILE` describes.
728 Any Git command accepting any <object> can also use the following
732 indicates the head of the current branch.
736 (i.e. a `refs/tags/<tag>` reference).
740 (i.e. a `refs/heads/<head>` reference).
742 For a more complete list of ways to spell object names, see
743 "SPECIFYING REVISIONS" section in linkgit:gitrevisions[7].
746 File/Directory Structure
747 ------------------------
749 Please see the linkgit:gitrepository-layout[5] document.
751 Read linkgit:githooks[5] for more details about each hook.
753 Higher level SCMs may provide and manage additional information in the
759 Please see linkgit:gitglossary[7].
762 Environment Variables
763 ---------------------
764 Various Git commands use the following environment variables:
768 These environment variables apply to 'all' core Git commands. Nb: it
769 is worth noting that they may be used/overridden by SCMS sitting above
770 Git so take care if using Cogito etc.
773 This environment allows the specification of an alternate
774 index file. If not specified, the default of `$GIT_DIR/index`
777 'GIT_INDEX_VERSION'::
778 This environment variable allows the specification of an index
779 version for new repositories. It won't affect existing index
780 files. By default index file version 2 or 3 is used. See
781 linkgit:git-update-index[1] for more information.
783 'GIT_OBJECT_DIRECTORY'::
784 If the object storage directory is specified via this
785 environment variable then the sha1 directories are created
786 underneath - otherwise the default `$GIT_DIR/objects`
789 'GIT_ALTERNATE_OBJECT_DIRECTORIES'::
790 Due to the immutable nature of Git objects, old objects can be
791 archived into shared, read-only directories. This variable
792 specifies a ":" separated (on Windows ";" separated) list
793 of Git object directories which can be used to search for Git
794 objects. New objects will not be written to these directories.
797 If the 'GIT_DIR' environment variable is set then it
798 specifies a path to use instead of the default `.git`
799 for the base of the repository.
800 The '--git-dir' command-line option also sets this value.
803 Set the path to the root of the working tree.
804 This can also be controlled by the '--work-tree' command-line
805 option and the core.worktree configuration variable.
808 Set the Git namespace; see linkgit:gitnamespaces[7] for details.
809 The '--namespace' command-line option also sets this value.
811 'GIT_CEILING_DIRECTORIES'::
812 This should be a colon-separated list of absolute paths. If
813 set, it is a list of directories that Git should not chdir up
814 into while looking for a repository directory (useful for
815 excluding slow-loading network directories). It will not
816 exclude the current working directory or a GIT_DIR set on the
817 command line or in the environment. Normally, Git has to read
818 the entries in this list and resolve any symlink that
819 might be present in order to compare them with the current
820 directory. However, if even this access is slow, you
821 can add an empty entry to the list to tell Git that the
822 subsequent entries are not symlinks and needn't be resolved;
824 'GIT_CEILING_DIRECTORIES=/maybe/symlink::/very/slow/non/symlink'.
826 'GIT_DISCOVERY_ACROSS_FILESYSTEM'::
827 When run in a directory that does not have ".git" repository
828 directory, Git tries to find such a directory in the parent
829 directories to find the top of the working tree, but by default it
830 does not cross filesystem boundaries. This environment variable
831 can be set to true to tell Git not to stop at filesystem
832 boundaries. Like 'GIT_CEILING_DIRECTORIES', this will not affect
833 an explicit repository directory set via 'GIT_DIR' or on the
841 'GIT_COMMITTER_NAME'::
842 'GIT_COMMITTER_EMAIL'::
843 'GIT_COMMITTER_DATE'::
845 see linkgit:git-commit-tree[1]
850 Only valid setting is "--unified=??" or "-u??" to set the
851 number of context lines shown when a unified diff is created.
852 This takes precedence over any "-U" or "--unified" option
853 value passed on the Git diff command line.
855 'GIT_EXTERNAL_DIFF'::
856 When the environment variable 'GIT_EXTERNAL_DIFF' is set, the
857 program named by it is called, instead of the diff invocation
858 described above. For a path that is added, removed, or modified,
859 'GIT_EXTERNAL_DIFF' is called with 7 parameters:
861 path old-file old-hex old-mode new-file new-hex new-mode
865 <old|new>-file:: are files GIT_EXTERNAL_DIFF can use to read the
866 contents of <old|new>,
867 <old|new>-hex:: are the 40-hexdigit SHA-1 hashes,
868 <old|new>-mode:: are the octal representation of the file modes.
870 The file parameters can point at the user's working file
871 (e.g. `new-file` in "git-diff-files"), `/dev/null` (e.g. `old-file`
872 when a new file is added), or a temporary file (e.g. `old-file` in the
873 index). 'GIT_EXTERNAL_DIFF' should not worry about unlinking the
874 temporary file --- it is removed when 'GIT_EXTERNAL_DIFF' exits.
876 For a path that is unmerged, 'GIT_EXTERNAL_DIFF' is called with 1
879 For each path 'GIT_EXTERNAL_DIFF' is called, two environment variables,
880 'GIT_DIFF_PATH_COUNTER' and 'GIT_DIFF_PATH_TOTAL' are set.
882 'GIT_DIFF_PATH_COUNTER'::
883 A 1-based counter incremented by one for every path.
885 'GIT_DIFF_PATH_TOTAL'::
886 The total number of paths.
890 'GIT_MERGE_VERBOSITY'::
891 A number controlling the amount of output shown by
892 the recursive merge strategy. Overrides merge.verbosity.
893 See linkgit:git-merge[1]
896 This environment variable overrides `$PAGER`. If it is set
897 to an empty string or to the value "cat", Git will not launch
898 a pager. See also the `core.pager` option in
899 linkgit:git-config[1].
902 This environment variable overrides `$EDITOR` and `$VISUAL`.
903 It is used by several Git commands when, on interactive mode,
904 an editor is to be launched. See also linkgit:git-var[1]
905 and the `core.editor` option in linkgit:git-config[1].
909 If either of these environment variables is set then 'git fetch'
910 and 'git push' will use the specified command instead of 'ssh'
911 when they need to connect to a remote system.
912 The command will be given exactly two or four arguments: the
913 'username@host' (or just 'host') from the URL and the shell
914 command to execute on that remote system, optionally preceded by
915 '-p' (literally) and the 'port' from the URL when it specifies
916 something other than the default SSH port.
918 `$GIT_SSH_COMMAND` takes precedence over `$GIT_SSH`, and is interpreted
919 by the shell, which allows additional arguments to be included.
920 `$GIT_SSH` on the other hand must be just the path to a program
921 (which can be a wrapper shell script, if additional arguments are
924 Usually it is easier to configure any desired options through your
925 personal `.ssh/config` file. Please consult your ssh documentation
929 If this environment variable is set, then Git commands which need to
930 acquire passwords or passphrases (e.g. for HTTP or IMAP authentication)
931 will call this program with a suitable prompt as command-line argument
932 and read the password from its STDOUT. See also the 'core.askPass'
933 option in linkgit:git-config[1].
935 'GIT_TERMINAL_PROMPT'::
936 If this environment variable is set to `0`, git will not prompt
937 on the terminal (e.g., when asking for HTTP authentication).
939 'GIT_CONFIG_NOSYSTEM'::
940 Whether to skip reading settings from the system-wide
941 `$(prefix)/etc/gitconfig` file. This environment variable can
942 be used along with `$HOME` and `$XDG_CONFIG_HOME` to create a
943 predictable environment for a picky script, or you can set it
944 temporarily to avoid using a buggy `/etc/gitconfig` file while
945 waiting for someone with sufficient permissions to fix it.
948 If this environment variable is set to "1", then commands such
949 as 'git blame' (in incremental mode), 'git rev-list', 'git log',
950 'git check-attr' and 'git check-ignore' will
951 force a flush of the output stream after each record have been
953 variable is set to "0", the output of these commands will be done
954 using completely buffered I/O. If this environment variable is
955 not set, Git will choose buffered or record-oriented flushing
956 based on whether stdout appears to be redirected to a file or not.
959 Enables general trace messages, e.g. alias expansion, built-in
960 command execution and external command execution.
962 If this variable is set to "1", "2" or "true" (comparison
963 is case insensitive), trace messages will be printed to
966 If the variable is set to an integer value greater than 2
967 and lower than 10 (strictly) then Git will interpret this
968 value as an open file descriptor and will try to write the
969 trace messages into this file descriptor.
971 Alternatively, if the variable is set to an absolute path
972 (starting with a '/' character), Git will interpret this
973 as a file path and will try to write the trace messages
976 Unsetting the variable, or setting it to empty, "0" or
977 "false" (case insensitive) disables trace messages.
979 'GIT_TRACE_PACK_ACCESS'::
980 Enables trace messages for all accesses to any packs. For each
981 access, the pack file name and an offset in the pack is
982 recorded. This may be helpful for troubleshooting some
983 pack-related performance problems.
984 See 'GIT_TRACE' for available trace output options.
987 Enables trace messages for all packets coming in or out of a
988 given program. This can help with debugging object negotiation
989 or other protocol issues. Tracing is turned off at a packet
990 starting with "PACK".
991 See 'GIT_TRACE' for available trace output options.
993 'GIT_TRACE_PERFORMANCE'::
994 Enables performance related trace messages, e.g. total execution
995 time of each Git command.
996 See 'GIT_TRACE' for available trace output options.
999 Enables trace messages printing the .git, working tree and current
1000 working directory after Git has completed its setup phase.
1001 See 'GIT_TRACE' for available trace output options.
1003 'GIT_TRACE_SHALLOW'::
1004 Enables trace messages that can help debugging fetching /
1005 cloning of shallow repositories.
1006 See 'GIT_TRACE' for available trace output options.
1008 GIT_LITERAL_PATHSPECS::
1009 Setting this variable to `1` will cause Git to treat all
1010 pathspecs literally, rather than as glob patterns. For example,
1011 running `GIT_LITERAL_PATHSPECS=1 git log -- '*.c'` will search
1012 for commits that touch the path `*.c`, not any paths that the
1013 glob `*.c` matches. You might want this if you are feeding
1014 literal paths to Git (e.g., paths previously given to you by
1015 `git ls-tree`, `--raw` diff output, etc).
1017 GIT_GLOB_PATHSPECS::
1018 Setting this variable to `1` will cause Git to treat all
1019 pathspecs as glob patterns (aka "glob" magic).
1021 GIT_NOGLOB_PATHSPECS::
1022 Setting this variable to `1` will cause Git to treat all
1023 pathspecs as literal (aka "literal" magic).
1025 GIT_ICASE_PATHSPECS::
1026 Setting this variable to `1` will cause Git to treat all
1027 pathspecs as case-insensitive.
1029 'GIT_REFLOG_ACTION'::
1030 When a ref is updated, reflog entries are created to keep
1031 track of the reason why the ref was updated (which is
1032 typically the name of the high-level command that updated
1033 the ref), in addition to the old and new values of the ref.
1034 A scripted Porcelain command can use set_reflog_action
1035 helper function in `git-sh-setup` to set its name to this
1036 variable when it is invoked as the top level command by the
1037 end user, to be recorded in the body of the reflog.
1039 `GIT_REF_PARANOIA`::
1040 If set to `1`, include broken or badly named refs when iterating
1041 over lists of refs. In a normal, non-corrupted repository, this
1042 does nothing. However, enabling it may help git to detect and
1043 abort some operations in the presence of broken refs. Git sets
1044 this variable automatically when performing destructive
1045 operations like linkgit:git-prune[1]. You should not need to set
1046 it yourself unless you want to be paranoid about making sure
1047 an operation has touched every ref (e.g., because you are
1048 cloning a repository to make a backup).
1051 Discussion[[Discussion]]
1052 ------------------------
1054 More detail on the following is available from the
1055 link:user-manual.html#git-concepts[Git concepts chapter of the
1056 user-manual] and linkgit:gitcore-tutorial[7].
1058 A Git project normally consists of a working directory with a ".git"
1059 subdirectory at the top level. The .git directory contains, among other
1060 things, a compressed object database representing the complete history
1061 of the project, an "index" file which links that history to the current
1062 contents of the working tree, and named pointers into that history such
1063 as tags and branch heads.
1065 The object database contains objects of three main types: blobs, which
1066 hold file data; trees, which point to blobs and other trees to build up
1067 directory hierarchies; and commits, which each reference a single tree
1068 and some number of parent commits.
1070 The commit, equivalent to what other systems call a "changeset" or
1071 "version", represents a step in the project's history, and each parent
1072 represents an immediately preceding step. Commits with more than one
1073 parent represent merges of independent lines of development.
1075 All objects are named by the SHA-1 hash of their contents, normally
1076 written as a string of 40 hex digits. Such names are globally unique.
1077 The entire history leading up to a commit can be vouched for by signing
1078 just that commit. A fourth object type, the tag, is provided for this
1081 When first created, objects are stored in individual files, but for
1082 efficiency may later be compressed together into "pack files".
1084 Named pointers called refs mark interesting points in history. A ref
1085 may contain the SHA-1 name of an object or the name of another ref. Refs
1086 with names beginning `ref/head/` contain the SHA-1 name of the most
1087 recent commit (or "head") of a branch under development. SHA-1 names of
1088 tags of interest are stored under `ref/tags/`. A special ref named
1089 `HEAD` contains the name of the currently checked-out branch.
1091 The index file is initialized with a list of all paths and, for each
1092 path, a blob object and a set of attributes. The blob object represents
1093 the contents of the file as of the head of the current branch. The
1094 attributes (last modified time, size, etc.) are taken from the
1095 corresponding file in the working tree. Subsequent changes to the
1096 working tree can be found by comparing these attributes. The index may
1097 be updated with new content, and new commits may be created from the
1098 content stored in the index.
1100 The index is also capable of storing multiple entries (called "stages")
1101 for a given pathname. These stages are used to hold the various
1102 unmerged version of a file when a merge is in progress.
1104 FURTHER DOCUMENTATION
