23 DESCRIPTION
24 -----------
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
27 escaped.
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 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 $HOME being properly set.
54 OPTIONS
55 -------
57 --replace-all::
58 Default behavior is to replace at most one line. This replaces
59 all lines matching the key (and optionally the value_regex).
61 --add::
62 Adds a new line to the option without altering any existing
63 values. This is the same as providing '^$' as the value_regex.
65 --get::
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.
70 --get-all::
71 Like get, but does not fail if the number of values for the key
72 is not exactly one.
74 --get-regexp::
75 Like --get-all, but interprets the name as a regular expression.
77 --global::
78 Use global ~/.gitconfig file rather than the repository .git/config.
80 --system::
81 Use system-wide $(prefix)/etc/gitconfig rather than the repository
82 .git/config.
84 --remove-section::
85 Remove the given section from the configuration file.
87 --rename-section::
88 Rename the given section to a new name.
90 --unset::
91 Remove the line matching the key from config file.
93 --unset-all::
94 Remove all lines matching the key from config file.
96 -l, --list::
97 List all variables set in config file.
99 --bool::
100 git-config will ensure that the output is "true" or "false"
102 --int::
103 git-config will ensure that the output is a simple
104 decimal number. An optional value suffix of 'k', 'm', or 'g'
105 in the config file will cause the value to be multiplied
106 by 1024, 1048576, or 1073741824 prior to output.
109 ENVIRONMENT
110 -----------
112 GIT_CONFIG::
113 Take the configuration from the given file instead of .git/config.
114 Using the "--global" option forces this to ~/.gitconfig.
116 GIT_CONFIG_LOCAL::
117 Currently the same as $GIT_CONFIG; when Git will support global
118 configuration files, this will cause it to take the configuration
119 from the global configuration file in addition to the given file.
122 EXAMPLE
123 -------
125 Given a .git/config like this:
127 #
128 # This is the config file, and
129 # a '#' or ';' character indicates
130 # a comment
131 #
133 ; core variables
134 [core]
135 ; Don't trust file modes
136 filemode = false
138 ; Our diff algorithm
139 [diff]
140 external = "/usr/local/bin/gnu-diff -u"
141 renames = true
143 ; Proxy settings
144 [core]
145 gitproxy="ssh" for "ssh://kernel.org/"
146 gitproxy="proxy-command" for kernel.org
147 gitproxy="myprotocol-command" for "my://"
148 gitproxy=default-proxy ; for all the rest
150 you can set the filemode to true with
152 ------------
153 % git config core.filemode true
154 ------------
156 The hypothetical proxy command entries actually have a postfix to discern
157 what URL they apply to. Here is how to change the entry for kernel.org
158 to "ssh".
160 ------------
161 % git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'
162 ------------
164 This makes sure that only the key/value pair for kernel.org is replaced.
166 To delete the entry for renames, do
168 ------------
169 % git config --unset diff.renames
170 ------------
172 If you want to delete an entry for a multivar (like core.gitproxy above),
173 you have to provide a regex matching the value of exactly one line.
175 To query the value for a given key, do
177 ------------
178 % git config --get core.filemode
179 ------------
181 or
183 ------------
184 % git config core.filemode
185 ------------
187 or, to query a multivar:
189 ------------
190 % git config --get core.gitproxy "for kernel.org$"
191 ------------
193 If you want to know all the values for a multivar, do:
195 ------------
196 % git config --get-all core.gitproxy
197 ------------
199 If you like to live dangerous, you can replace *all* core.gitproxy by a
200 new one with
202 ------------
203 % git config --replace-all core.gitproxy ssh
204 ------------
206 However, if you really only want to replace the line for the default proxy,
207 i.e. the one without a "for ..." postfix, do something like this:
209 ------------
210 % git config core.gitproxy ssh '! for '
211 ------------
213 To actually match only values with an exclamation mark, you have to
215 ------------
216 % git config section.key value '[!]'
217 ------------
219 To add a new proxy, without altering any of the existing ones, use
221 ------------
222 % git config core.gitproxy '"proxy" for example.com'
223 ------------
