27 DESCRIPTION
28 -----------
29 You can query/set/replace/unset options with this command. The name is
30 actually the section and the key separated by a dot, and the value will be
31 escaped.
33 Multiple lines can be added to an option by using the '--add' option.
34 If you want to update or unset an option which can occur on multiple
35 lines, a POSIX regexp `value_regex` needs to be given. Only the
36 existing values that match the regexp are updated or unset. If
37 you want to handle the lines that do *not* match the regex, just
38 prepend a single exclamation mark in front (see also <<EXAMPLES>>).
40 The type specifier can be either '--int' or '--bool', which will make
41 'git-config' ensure that the variable(s) are of the given type and
42 convert the value to the canonical form (simple decimal number for int,
43 a "true" or "false" string for bool). If no type specifier is passed,
44 no checks or transformations are performed on the value.
46 The file-option can be one of '--system', '--global' or '--file'
47 which specify where the values will be read from or written to.
48 The default is to assume the config file of the current repository,
49 .git/config unless defined otherwise with GIT_DIR and GIT_CONFIG
50 (see <<FILES>>).
52 This command will fail if:
54 . The config file is invalid,
55 . Can not write to the config file,
56 . no section was provided,
57 . the section or key is invalid,
58 . you try to unset an option which does not exist,
59 . you try to unset/set an option for which multiple lines match, or
60 . you use '--global' option without $HOME being properly set.
63 OPTIONS
64 -------
66 --replace-all::
67 Default behavior is to replace at most one line. This replaces
68 all lines matching the key (and optionally the value_regex).
70 --add::
71 Adds a new line to the option without altering any existing
72 values. This is the same as providing '^$' as the value_regex
73 in `--replace-all`.
75 --get::
76 Get the value for a given key (optionally filtered by a regex
77 matching the value). Returns error code 1 if the key was not
78 found and error code 2 if multiple key values were found.
80 --get-all::
81 Like get, but does not fail if the number of values for the key
82 is not exactly one.
84 --get-regexp::
85 Like --get-all, but interprets the name as a regular expression.
86 Also outputs the key names.
88 --global::
89 For writing options: write to global ~/.gitconfig file rather than
90 the repository .git/config.
91 +
92 For reading options: read only from global ~/.gitconfig rather than
93 from all available files.
94 +
95 See also <<FILES>>.
97 --system::
98 For writing options: write to system-wide $(prefix)/etc/gitconfig
99 rather than the repository .git/config.
100 +
101 For reading options: read only from system-wide $(prefix)/etc/gitconfig
102 rather than from all available files.
103 +
104 See also <<FILES>>.
106 -f config-file::
107 --file config-file::
108 Use the given config file instead of the one specified by GIT_CONFIG.
110 --remove-section::
111 Remove the given section from the configuration file.
113 --rename-section::
114 Rename the given section to a new name.
116 --unset::
117 Remove the line matching the key from config file.
119 --unset-all::
120 Remove all lines matching the key from config file.
122 -l::
123 --list::
124 List all variables set in config file.
126 --bool::
127 'git-config' will ensure that the output is "true" or "false"
129 --int::
130 'git-config' will ensure that the output is a simple
131 decimal number. An optional value suffix of 'k', 'm', or 'g'
132 in the config file will cause the value to be multiplied
133 by 1024, 1048576, or 1073741824 prior to output.
135 --bool-or-int::
136 'git-config' will ensure that the output matches the format of
137 either --bool or --int, as described above.
139 -z::
140 --null::
141 For all options that output values and/or keys, always
142 end values with the null character (instead of a
143 newline). Use newline instead as a delimiter between
144 key and value. This allows for secure parsing of the
145 output without getting confused e.g. by values that
146 contain line breaks.
148 --get-colorbool name [stdout-is-tty]::
150 Find the color setting for `name` (e.g. `color.diff`) and output
151 "true" or "false". `stdout-is-tty` should be either "true" or
152 "false", and is taken into account when configuration says
153 "auto". If `stdout-is-tty` is missing, then checks the standard
154 output of the command itself, and exits with status 0 if color
155 is to be used, or exits with status 1 otherwise.
156 When the color setting for `name` is undefined, the command uses
157 `color.ui` as fallback.
159 --get-color name [default]::
161 Find the color configured for `name` (e.g. `color.diff.new`) and
162 output it as the ANSI color escape sequence to the standard
163 output. The optional `default` parameter is used instead, if
164 there is no color configured for `name`.
166 -e::
167 --edit::
168 Opens an editor to modify the specified config file; either
169 '--system', '--global', or repository (default).
171 [[FILES]]
172 FILES
173 -----
175 If not set explicitly with '--file', there are three files where
176 'git-config' will search for configuration options:
178 $GIT_DIR/config::
179 Repository specific configuration file. (The filename is
180 of course relative to the repository root, not the working
181 directory.)
183 ~/.gitconfig::
184 User-specific configuration file. Also called "global"
185 configuration file.
187 $(prefix)/etc/gitconfig::
188 System-wide configuration file.
190 If no further options are given, all reading options will read all of these
191 files that are available. If the global or the system-wide configuration
192 file are not available they will be ignored. If the repository configuration
193 file is not available or readable, 'git-config' will exit with a non-zero
194 error code. However, in neither case will an error message be issued.
196 All writing options will per default write to the repository specific
197 configuration file. Note that this also affects options like '--replace-all'
198 and '--unset'. *'git-config' will only ever change one file at a time*.
200 You can override these rules either by command line options or by environment
201 variables. The '--global' and the '--system' options will limit the file used
202 to the global or system-wide file respectively. The GIT_CONFIG environment
203 variable has a similar effect, but you can specify any filename you want.
206 ENVIRONMENT
207 -----------
209 GIT_CONFIG::
210 Take the configuration from the given file instead of .git/config.
211 Using the "--global" option forces this to ~/.gitconfig. Using the
212 "--system" option forces this to $(prefix)/etc/gitconfig.
214 See also <<FILES>>.
217 [[EXAMPLES]]
218 EXAMPLES
219 --------
221 Given a .git/config like this:
223 #
224 # This is the config file, and
225 # a '#' or ';' character indicates
226 # a comment
227 #
229 ; core variables
230 [core]
231 ; Don't trust file modes
232 filemode = false
234 ; Our diff algorithm
235 [diff]
236 external = /usr/local/bin/diff-wrapper
237 renames = true
239 ; Proxy settings
240 [core]
241 gitproxy="proxy-command" for kernel.org
242 gitproxy=default-proxy ; for all the rest
244 you can set the filemode to true with
246 ------------
247 % git config core.filemode true
248 ------------
250 The hypothetical proxy command entries actually have a postfix to discern
251 what URL they apply to. Here is how to change the entry for kernel.org
252 to "ssh".
254 ------------
255 % git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'
256 ------------
258 This makes sure that only the key/value pair for kernel.org is replaced.
260 To delete the entry for renames, do
262 ------------
263 % git config --unset diff.renames
264 ------------
266 If you want to delete an entry for a multivar (like core.gitproxy above),
267 you have to provide a regex matching the value of exactly one line.
269 To query the value for a given key, do
271 ------------
272 % git config --get core.filemode
273 ------------
275 or
277 ------------
278 % git config core.filemode
279 ------------
281 or, to query a multivar:
283 ------------
284 % git config --get core.gitproxy "for kernel.org$"
285 ------------
287 If you want to know all the values for a multivar, do:
289 ------------
290 % git config --get-all core.gitproxy
291 ------------
293 If you like to live dangerously, you can replace *all* core.gitproxy by a
294 new one with
296 ------------
297 % git config --replace-all core.gitproxy ssh
298 ------------
300 However, if you really only want to replace the line for the default proxy,
301 i.e. the one without a "for ..." postfix, do something like this:
303 ------------
304 % git config core.gitproxy ssh '! for '
305 ------------
307 To actually match only values with an exclamation mark, you have to
309 ------------
310 % git config section.key value '[!]'
311 ------------
313 To add a new proxy, without altering any of the existing ones, use
315 ------------
316 % git config core.gitproxy '"proxy-command" for example.com'
317 ------------
319 An example to use customized color from the configuration in your
320 script:
322 ------------
323 #!/bin/sh
324 WS=$(git config --get-color color.diff.whitespace "blue reverse")
325 RESET=$(git config --get-color "" "reset")
326 echo "${WS}your whitespace color or blue reverse${RESET}"
