6 git-config - Get and set repository or global options
12 'git-config' [<file-option>] [type] [-z|--null] name [value [value_regex]]
13 'git-config' [<file-option>] [type] --add name value
14 'git-config' [<file-option>] [type] --replace-all name [value [value_regex]]
15 'git-config' [<file-option>] [type] [-z|--null] --get name [value_regex]
16 'git-config' [<file-option>] [type] [-z|--null] --get-all name [value_regex]
17 'git-config' [<file-option>] [type] [-z|--null] --get-regexp name_regex [value_regex]
18 'git-config' [<file-option>] --unset name [value_regex]
19 'git-config' [<file-option>] --unset-all name [value_regex]
20 'git-config' [<file-option>] --rename-section old_name new_name
21 'git-config' [<file-option>] --remove-section name
22 'git-config' [<file-option>] [-z|--null] -l | --list
26 You can query/set/replace/unset options with this command. The name is
27 actually the section and the key separated by a dot, and the value will be
30 Multiple lines can be added to an option by using the '--add' option.
31 If you want to update or unset an option which can occur on multiple
32 lines, a POSIX regexp `value_regex` needs to be given. Only the
33 existing values that match the regexp are updated or unset. If
34 you want to handle the lines that do *not* match the regex, just
35 prepend a single exclamation mark in front (see also <<EXAMPLES>>).
37 The type specifier can be either '--int' or '--bool', which will make
38 'git-config' ensure that the variable(s) are of the given type and
39 convert the value to the canonical form (simple decimal number for int,
40 a "true" or "false" string for bool). If no type specifier is passed,
41 no checks or transformations are performed on the value.
43 The file-option can be one of '--system', '--global' or '--file'
44 which specify where the values will be read from or written to.
45 The default is to assume the config file of the current repository,
46 .git/config unless defined otherwise with GIT_DIR and GIT_CONFIG
49 This command will fail if:
51 . The config file is invalid,
52 . Can not write to the config file,
53 . no section was provided,
54 . the section or key is invalid,
55 . you try to unset an option which does not exist,
56 . you try to unset/set an option for which multiple lines match, or
57 . you use '--global' option without $HOME being properly set.
64 Default behavior is to replace at most one line. This replaces
65 all lines matching the key (and optionally the value_regex).
68 Adds a new line to the option without altering any existing
69 values. This is the same as providing '^$' as the value_regex.
72 Get the value for a given key (optionally filtered by a regex
73 matching the value). Returns error code 1 if the key was not
74 found and error code 2 if multiple key values were found.
77 Like get, but does not fail if the number of values for the key
81 Like --get-all, but interprets the name as a regular expression.
82 Also outputs the key names.
85 For writing options: write to global ~/.gitconfig file rather than
86 the repository .git/config.
88 For reading options: read only from global ~/.gitconfig rather than
89 from all available files.
94 For writing options: write to system-wide $(prefix)/etc/gitconfig
95 rather than the repository .git/config.
97 For reading options: read only from system-wide $(prefix)/etc/gitconfig
98 rather than from all available files.
102 -f config-file, --file config-file::
103 Use the given config file instead of the one specified by GIT_CONFIG.
106 Remove the given section from the configuration file.
109 Rename the given section to a new name.
112 Remove the line matching the key from config file.
115 Remove all lines matching the key from config file.
118 List all variables set in config file.
121 git-config will ensure that the output is "true" or "false"
124 git-config will ensure that the output is a simple
125 decimal number. An optional value suffix of 'k', 'm', or 'g'
126 in the config file will cause the value to be multiplied
127 by 1024, 1048576, or 1073741824 prior to output.
130 For all options that output values and/or keys, always
131 end values with with the null character (instead of a
132 newline). Use newline instead as a delimiter between
133 key and value. This allows for secure parsing of the
134 output without getting confused e.g. by values that
142 If not set explicitely with '--file', there are three files where
143 git-config will search for configuration options:
146 Repository specific configuration file. (The filename is
147 of course relative to the repository root, not the working
151 User-specific configuration file. Also called "global"
154 $(prefix)/etc/gitconfig::
155 System-wide configuration file.
157 If no further options are given, all reading options will read all of these
158 files that are available. If the global or the system-wide configuration
159 file are not available they will be ignored. If the repository configuration
160 file is not available or readable, git-config will exit with a non-zero
161 error code. However, in neither case will an error message be issued.
163 All writing options will per default write to the repository specific
164 configuration file. Note that this also affects options like '--replace-all'
165 and '--unset'. *git-config will only ever change one file at a time*.
167 You can override these rules either by command line options or by environment
168 variables. The '--global' and the '--system' options will limit the file used
169 to the global or system-wide file respectively. The GIT_CONFIG environment
170 variable has a similar effect, but you can specify any filename you want.
172 The GIT_CONFIG_LOCAL environment variable on the other hand only changes
173 the name used instead of the repository configuration file. The global and
174 the system-wide configuration files will still be read. (For writing options
175 this will obviously result in the same behavior as using GIT_CONFIG.)
182 Take the configuration from the given file instead of .git/config.
183 Using the "--global" option forces this to ~/.gitconfig. Using the
184 "--system" option forces this to $(prefix)/etc/gitconfig.
187 Take the configuration from the given file instead if .git/config.
188 Still read the global and the system-wide configuration files, though.
197 Given a .git/config like this:
200 # This is the config file, and
201 # a '#' or ';' character indicates
207 ; Don't trust file modes
212 external = "/usr/local/bin/gnu-diff -u"
217 gitproxy="proxy-command" for kernel.org
218 gitproxy=default-proxy ; for all the rest
220 you can set the filemode to true with
223 % git config core.filemode true
226 The hypothetical proxy command entries actually have a postfix to discern
227 what URL they apply to. Here is how to change the entry for kernel.org
231 % git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'
234 This makes sure that only the key/value pair for kernel.org is replaced.
236 To delete the entry for renames, do
239 % git config --unset diff.renames
242 If you want to delete an entry for a multivar (like core.gitproxy above),
243 you have to provide a regex matching the value of exactly one line.
245 To query the value for a given key, do
248 % git config --get core.filemode
254 % git config core.filemode
257 or, to query a multivar:
260 % git config --get core.gitproxy "for kernel.org$"
263 If you want to know all the values for a multivar, do:
266 % git config --get-all core.gitproxy
269 If you like to live dangerous, you can replace *all* core.gitproxy by a
273 % git config --replace-all core.gitproxy ssh
276 However, if you really only want to replace the line for the default proxy,
277 i.e. the one without a "for ..." postfix, do something like this:
280 % git config core.gitproxy ssh '! for '
283 To actually match only values with an exclamation mark, you have to
286 % git config section.key value '[!]'
289 To add a new proxy, without altering any of the existing ones, use
292 % git config core.gitproxy '"proxy-command" for example.com'
