6 git-config - Get and set repository or global options
12 'git-config' [--system | --global] name [value [value_regex]]
13 'git-config' [--system | --global] --add name value
14 'git-config' [--system | --global] --replace-all name [value [value_regex]]
15 'git-config' [--system | --global] [type] --get name [value_regex]
16 'git-config' [--system | --global] [type] --get-all name [value_regex]
17 'git-config' [--system | --global] --unset name [value_regex]
18 'git-config' [--system | --global] --unset-all name [value_regex]
19 'git-config' [--system | --global] --rename-section old_name new_name
20 'git-config' [--system | --global] --remove-section name
21 'git-config' [--system | --global] -l | --list
25 You can query/set/replace/unset options with this command. The name is
26 actually the section and the key separated by a dot, and the value will be
29 Multiple lines can be added to an option by using the '--add' option.
30 If you want to update or unset an option which can occur on multiple
31 lines, a POSIX regexp `value_regex` needs to be given. Only the
32 existing values that match the regexp are updated or unset. If
33 you want to handle the lines that do *not* match the regex, just
34 prepend a single exclamation mark in front (see also <<EXAMPLES>>).
36 The type specifier can be either '--int' or '--bool', which will make
37 'git-config' ensure that the variable(s) are of the given type and
38 convert the value to the canonical form (simple decimal number for int,
39 a "true" or "false" string for bool). Type specifiers currently only
40 take effect for reading operations. If no type specifier is passed,
41 no checks or transformations are performed on the value.
43 This command will fail if:
45 . The .git/config file is invalid,
46 . Can not write to .git/config,
47 . no section was provided,
48 . the section or key is invalid,
49 . you try to unset an option which does not exist,
50 . you try to unset/set an option for which multiple lines match, or
51 . you use '--global' option without $HOME being properly set.
58 Default behavior is to replace at most one line. This replaces
59 all lines matching the key (and optionally the value_regex).
62 Adds a new line to the option without altering any existing
63 values. This is the same as providing '^$' as the value_regex.
66 Get the value for a given key (optionally filtered by a regex
67 matching the value). Returns error code 1 if the key was not
68 found and error code 2 if multiple key values were found.
71 Like get, but does not fail if the number of values for the key
75 Like --get-all, but interprets the name as a regular expression.
78 For writing options: write to global ~/.gitconfig file rather than
79 the repository .git/config.
81 For reading options: read only from global ~/.gitconfig rather than
82 from all available files.
87 For writing options: write to system-wide $(prefix)/etc/gitconfig
88 rather than the repository .git/config.
90 For reading options: read only from system-wide $(prefix)/etc/gitconfig
91 rather than from all available files.
96 Remove the given section from the configuration file.
99 Rename the given section to a new name.
102 Remove the line matching the key from config file.
105 Remove all lines matching the key from config file.
108 List all variables set in config file.
111 git-config will ensure that the output is "true" or "false"
114 git-config will ensure that the output is a simple
115 decimal number. An optional value suffix of 'k', 'm', or 'g'
116 in the config file will cause the value to be multiplied
117 by 1024, 1048576, or 1073741824 prior to output.
124 There are three files where git-config will search for configuration
128 Repository specific configuration file. (The filename is
129 of course relative to the repository root, not the working
133 User-specific configuration file. Also called "global"
136 $(prefix)/etc/gitconfig::
137 System-wide configuration file.
139 If no further options are given, all reading options will read all of these
140 files that are available. If the global or the system-wide configuration
141 file are not available they will be ignored. If the repository configuration
142 file is not available or readable, git-config will exit with a non-zero
143 error code. However, in neither case will an error message be issued.
145 All writing options will per default write to the repository specific
146 configuration file. Note that this also affects options like '--replace-all'
147 and '--unset'. *git-config will only ever change one file at a time*.
149 You can override these rules either by command line options or by environment
150 variables. The '--global' and the '--system' options will limit the file used
151 to the global or system-wide file respectively. The GIT_CONFIG environment
152 variable has a similar effect, but you can specify any filename you want.
154 The GIT_CONFIG_LOCAL environment variable on the other hand only changes
155 the name used instead of the repository configuration file. The global and
156 the system-wide configuration files will still be read. (For writing options
157 this will obviously result in the same behavior as using GIT_CONFIG.)
164 Take the configuration from the given file instead of .git/config.
165 Using the "--global" option forces this to ~/.gitconfig. Using the
166 "--system" option forces this to $(prefix)/etc/gitconfig.
169 Take the configuration from the given file instead if .git/config.
170 Still read the global and the system-wide configuration files, though.
179 Given a .git/config like this:
182 # This is the config file, and
183 # a '#' or ';' character indicates
189 ; Don't trust file modes
194 external = "/usr/local/bin/gnu-diff -u"
199 gitproxy="ssh" for "ssh://kernel.org/"
200 gitproxy="proxy-command" for kernel.org
201 gitproxy="myprotocol-command" for "my://"
202 gitproxy=default-proxy ; for all the rest
204 you can set the filemode to true with
207 % git config core.filemode true
210 The hypothetical proxy command entries actually have a postfix to discern
211 what URL they apply to. Here is how to change the entry for kernel.org
215 % git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'
218 This makes sure that only the key/value pair for kernel.org is replaced.
220 To delete the entry for renames, do
223 % git config --unset diff.renames
226 If you want to delete an entry for a multivar (like core.gitproxy above),
227 you have to provide a regex matching the value of exactly one line.
229 To query the value for a given key, do
232 % git config --get core.filemode
238 % git config core.filemode
241 or, to query a multivar:
244 % git config --get core.gitproxy "for kernel.org$"
247 If you want to know all the values for a multivar, do:
250 % git config --get-all core.gitproxy
253 If you like to live dangerous, you can replace *all* core.gitproxy by a
257 % git config --replace-all core.gitproxy ssh
260 However, if you really only want to replace the line for the default proxy,
261 i.e. the one without a "for ..." postfix, do something like this:
264 % git config core.gitproxy ssh '! for '
267 To actually match only values with an exclamation mark, you have to
270 % git config section.key value '[!]'
273 To add a new proxy, without altering any of the existing ones, use
276 % git config core.gitproxy '"proxy" for example.com'
