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.
74 --get::
75 Get the value for a given key (optionally filtered by a regex
76 matching the value). Returns error code 1 if the key was not
77 found and error code 2 if multiple key values were found.
79 --get-all::
80 Like get, but does not fail if the number of values for the key
81 is not exactly one.
83 --get-regexp::
84 Like --get-all, but interprets the name as a regular expression.
85 Also outputs the key names.
87 --global::
88 For writing options: write to global ~/.gitconfig file rather than
89 the repository .git/config.
90 +
91 For reading options: read only from global ~/.gitconfig rather than
92 from all available files.
93 +
94 See also <<FILES>>.
96 --system::
97 For writing options: write to system-wide $(prefix)/etc/gitconfig
98 rather than the repository .git/config.
99 +
100 For reading options: read only from system-wide $(prefix)/etc/gitconfig
101 rather than from all available files.
102 +
103 See also <<FILES>>.
105 -f config-file::
106 --file config-file::
107 Use the given config file instead of the one specified by GIT_CONFIG.
109 --remove-section::
110 Remove the given section from the configuration file.
112 --rename-section::
113 Rename the given section to a new name.
115 --unset::
116 Remove the line matching the key from config file.
118 --unset-all::
119 Remove all lines matching the key from config file.
121 -l::
122 --list::
123 List all variables set in config file.
125 --bool::
126 'git-config' will ensure that the output is "true" or "false"
128 --int::
129 'git-config' will ensure that the output is a simple
130 decimal number. An optional value suffix of 'k', 'm', or 'g'
131 in the config file will cause the value to be multiplied
132 by 1024, 1048576, or 1073741824 prior to output.
134 -z::
135 --null::
136 For all options that output values and/or keys, always
137 end values with the null character (instead of a
138 newline). Use newline instead as a delimiter between
139 key and value. This allows for secure parsing of the
140 output without getting confused e.g. by values that
141 contain line breaks.
143 --get-colorbool name [stdout-is-tty]::
145 Find the color setting for `name` (e.g. `color.diff`) and output
146 "true" or "false". `stdout-is-tty` should be either "true" or
147 "false", and is taken into account when configuration says
148 "auto". If `stdout-is-tty` is missing, then checks the standard
149 output of the command itself, and exits with status 0 if color
150 is to be used, or exits with status 1 otherwise.
151 When the color setting for `name` is undefined, the command uses
152 `color.ui` as fallback.
154 --get-color name default::
156 Find the color configured for `name` (e.g. `color.diff.new`) and
157 output it as the ANSI color escape sequence to the standard
158 output. The optional `default` parameter is used instead, if
159 there is no color configured for `name`.
161 -e::
162 --edit::
163 Opens an editor to modify the specified config file; either
164 '--system', '--global', or repository (default).
166 [[FILES]]
167 FILES
168 -----
170 If not set explicitly with '--file', there are three files where
171 'git-config' will search for configuration options:
173 $GIT_DIR/config::
174 Repository specific configuration file. (The filename is
175 of course relative to the repository root, not the working
176 directory.)
178 ~/.gitconfig::
179 User-specific configuration file. Also called "global"
180 configuration file.
182 $(prefix)/etc/gitconfig::
183 System-wide configuration file.
185 If no further options are given, all reading options will read all of these
186 files that are available. If the global or the system-wide configuration
187 file are not available they will be ignored. If the repository configuration
188 file is not available or readable, 'git-config' will exit with a non-zero
189 error code. However, in neither case will an error message be issued.
191 All writing options will per default write to the repository specific
192 configuration file. Note that this also affects options like '--replace-all'
193 and '--unset'. *'git-config' will only ever change one file at a time*.
195 You can override these rules either by command line options or by environment
196 variables. The '--global' and the '--system' options will limit the file used
197 to the global or system-wide file respectively. The GIT_CONFIG environment
198 variable has a similar effect, but you can specify any filename you want.
201 ENVIRONMENT
202 -----------
204 GIT_CONFIG::
205 Take the configuration from the given file instead of .git/config.
206 Using the "--global" option forces this to ~/.gitconfig. Using the
207 "--system" option forces this to $(prefix)/etc/gitconfig.
209 See also <<FILES>>.
212 [[EXAMPLES]]
213 EXAMPLES
214 --------
216 Given a .git/config like this:
218 #
219 # This is the config file, and
220 # a '#' or ';' character indicates
221 # a comment
222 #
224 ; core variables
225 [core]
226 ; Don't trust file modes
227 filemode = false
229 ; Our diff algorithm
230 [diff]
231 external = /usr/local/bin/diff-wrapper
232 renames = true
234 ; Proxy settings
235 [core]
236 gitproxy="proxy-command" for kernel.org
237 gitproxy=default-proxy ; for all the rest
239 you can set the filemode to true with
241 ------------
242 % git config core.filemode true
243 ------------
245 The hypothetical proxy command entries actually have a postfix to discern
246 what URL they apply to. Here is how to change the entry for kernel.org
247 to "ssh".
249 ------------
250 % git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'
251 ------------
253 This makes sure that only the key/value pair for kernel.org is replaced.
255 To delete the entry for renames, do
257 ------------
258 % git config --unset diff.renames
259 ------------
261 If you want to delete an entry for a multivar (like core.gitproxy above),
262 you have to provide a regex matching the value of exactly one line.
264 To query the value for a given key, do
266 ------------
267 % git config --get core.filemode
268 ------------
270 or
272 ------------
273 % git config core.filemode
274 ------------
276 or, to query a multivar:
278 ------------
279 % git config --get core.gitproxy "for kernel.org$"
280 ------------
282 If you want to know all the values for a multivar, do:
284 ------------
285 % git config --get-all core.gitproxy
286 ------------
288 If you like to live dangerously, you can replace *all* core.gitproxy by a
289 new one with
291 ------------
292 % git config --replace-all core.gitproxy ssh
293 ------------
295 However, if you really only want to replace the line for the default proxy,
296 i.e. the one without a "for ..." postfix, do something like this:
298 ------------
299 % git config core.gitproxy ssh '! for '
300 ------------
302 To actually match only values with an exclamation mark, you have to
304 ------------
305 % git config section.key value '[!]'
306 ------------
308 To add a new proxy, without altering any of the existing ones, use
310 ------------
311 % git config core.gitproxy '"proxy-command" for example.com'
312 ------------
314 An example to use customized color from the configuration in your
315 script:
317 ------------
318 #!/bin/sh
319 WS=$(git config --get-color color.diff.whitespace "blue reverse")
320 RESET=$(git config --get-color "" "reset")
321 echo "${WS}your whitespace color or blue reverse${RESET}"
