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] [type] --get-regexp name_regex [value_regex]
18 'git-config' [--system | --global] --unset name [value_regex]
19 'git-config' [--system | --global] --unset-all name [value_regex]
20 'git-config' [--system | --global] --rename-section old_name new_name
21 'git-config' [--system | --global] --remove-section name
22 'git-config' [--system | --global] -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). Type specifiers currently only
41 take effect for reading operations. If no type specifier is passed,
42 no checks or transformations are performed on the value.
44 This command will fail if:
46 . The .git/config file is invalid,
47 . Can not write to .git/config,
48 . no section was provided,
49 . the section or key is invalid,
50 . you try to unset an option which does not exist,
51 . you try to unset/set an option for which multiple lines match, or
52 . you use '--global' option without $HOME being properly set.
59 Default behavior is to replace at most one line. This replaces
60 all lines matching the key (and optionally the value_regex).
63 Adds a new line to the option without altering any existing
64 values. This is the same as providing '^$' as the value_regex.
67 Get the value for a given key (optionally filtered by a regex
68 matching the value). Returns error code 1 if the key was not
69 found and error code 2 if multiple key values were found.
72 Like get, but does not fail if the number of values for the key
76 Like --get-all, but interprets the name as a regular expression.
77 Also outputs the key names.
80 For writing options: write to global ~/.gitconfig file rather than
81 the repository .git/config.
83 For reading options: read only from global ~/.gitconfig rather than
84 from all available files.
89 For writing options: write to system-wide $(prefix)/etc/gitconfig
90 rather than the repository .git/config.
92 For reading options: read only from system-wide $(prefix)/etc/gitconfig
93 rather than from all available files.
98 Remove the given section from the configuration file.
101 Rename the given section to a new name.
104 Remove the line matching the key from config file.
107 Remove all lines matching the key from config file.
110 List all variables set in config file.
113 git-config will ensure that the output is "true" or "false"
116 git-config will ensure that the output is a simple
117 decimal number. An optional value suffix of 'k', 'm', or 'g'
118 in the config file will cause the value to be multiplied
119 by 1024, 1048576, or 1073741824 prior to output.
126 There are three files where git-config will search for configuration
130 Repository specific configuration file. (The filename is
131 of course relative to the repository root, not the working
135 User-specific configuration file. Also called "global"
138 $(prefix)/etc/gitconfig::
139 System-wide configuration file.
141 If no further options are given, all reading options will read all of these
142 files that are available. If the global or the system-wide configuration
143 file are not available they will be ignored. If the repository configuration
144 file is not available or readable, git-config will exit with a non-zero
145 error code. However, in neither case will an error message be issued.
147 All writing options will per default write to the repository specific
148 configuration file. Note that this also affects options like '--replace-all'
149 and '--unset'. *git-config will only ever change one file at a time*.
151 You can override these rules either by command line options or by environment
152 variables. The '--global' and the '--system' options will limit the file used
153 to the global or system-wide file respectively. The GIT_CONFIG environment
154 variable has a similar effect, but you can specify any filename you want.
156 The GIT_CONFIG_LOCAL environment variable on the other hand only changes
157 the name used instead of the repository configuration file. The global and
158 the system-wide configuration files will still be read. (For writing options
159 this will obviously result in the same behavior as using GIT_CONFIG.)
166 Take the configuration from the given file instead of .git/config.
167 Using the "--global" option forces this to ~/.gitconfig. Using the
168 "--system" option forces this to $(prefix)/etc/gitconfig.
171 Take the configuration from the given file instead if .git/config.
172 Still read the global and the system-wide configuration files, though.
181 Given a .git/config like this:
184 # This is the config file, and
185 # a '#' or ';' character indicates
191 ; Don't trust file modes
196 external = "/usr/local/bin/gnu-diff -u"
201 gitproxy="ssh" for "ssh://kernel.org/"
202 gitproxy="proxy-command" for kernel.org
203 gitproxy="myprotocol-command" for "my://"
204 gitproxy=default-proxy ; for all the rest
206 you can set the filemode to true with
209 % git config core.filemode true
212 The hypothetical proxy command entries actually have a postfix to discern
213 what URL they apply to. Here is how to change the entry for kernel.org
217 % git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'
220 This makes sure that only the key/value pair for kernel.org is replaced.
222 To delete the entry for renames, do
225 % git config --unset diff.renames
228 If you want to delete an entry for a multivar (like core.gitproxy above),
229 you have to provide a regex matching the value of exactly one line.
231 To query the value for a given key, do
234 % git config --get core.filemode
240 % git config core.filemode
243 or, to query a multivar:
246 % git config --get core.gitproxy "for kernel.org$"
249 If you want to know all the values for a multivar, do:
252 % git config --get-all core.gitproxy
255 If you like to live dangerous, you can replace *all* core.gitproxy by a
259 % git config --replace-all core.gitproxy ssh
262 However, if you really only want to replace the line for the default proxy,
263 i.e. the one without a "for ..." postfix, do something like this:
266 % git config core.gitproxy ssh '! for '
269 To actually match only values with an exclamation mark, you have to
272 % git config section.key value '[!]'
275 To add a new proxy, without altering any of the existing ones, use
278 % git config core.gitproxy '"proxy" for example.com'
