The name is 30actually the section and the key separated by a dot, and the value will be 31escaped. 32 33Multiple lines can be added to an option by using the '--add' option. 34If you want to update or unset an option which can occur on multiple 35lines, a POSIX regexp `value_regex` needs to be given. Only the 36existing values that match the regexp are updated or unset. If 37you want to handle the lines that do *not* match the regex, just 38prepend a single exclamation mark in front (see also <<EXAMPLES>>). 39 40The 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 42convert the value to the canonical form (simple decimal number for int, 43a "true" or "false" string for bool). If no type specifier is passed, 44no checks or transformations are performed on the value. 45 46The file-option can be one of '--system', '--global' or '--file' 47which specify where the values will be read from or written to. 48The 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>>). 51 52This command will fail if: 53 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 $HOME being properly set. 61 62 63OPTIONS 64------- 65 66--replace-all:: 67 Default behavior is to replace at most one line. This replaces 68 all lines matching the key (and optionally the value_regex). 69 70--add:: 71 Adds a new line to the option without altering any existing 72 values. This is the same as providing '^$' as the value_regex. 73 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. 78 79--get-all:: 80 Like get, but does not fail if the number of values for the key 81 is not exactly one. 82 83--get-regexp:: 84 Like --get-all, but interprets the name as a regular expression. 85 Also outputs the key names. 86 87--global:: 88 For writing options: write to global ~/.gitconfig file rather than 89 the repository .git/config. 90+ 91For reading options: read only from global ~/.gitconfig rather than 92from all available files. 93+ 94See also <<FILES>>. 95 96--system:: 97 For writing options: write to system-wide $(prefix)/etc/gitconfig 98 rather than the repository .git/config. 99+ 100For reading options: read only from system-wide $(prefix)/etc/gitconfig 101rather than from all available files. 102+ 103See also <<FILES>>. 104 105-f config-file:: 106--file config-file:: 107 Use the given config file instead of the one specified by GIT_CONFIG. 108 109--remove-section:: 110 Remove the given section from the configuration file. 111 112--rename-section:: 113 Rename the given section to a new name. 114 115--unset:: 116 Remove the line matching the key from config file. 117 118--unset-all:: 119 Remove all lines matching the key from config file. 120 121-l:: 122--list:: 123 List all variables set in config file. 124 125--bool:: 126 'git-config' will ensure that the output is "true" or "false" 127 128--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. 133 134--bool-or-int:: 135 'git-config' will ensure that the output matches the format of 136 either --bool or --int, as described above. 137 138-z:: 139--null:: 140 For all options that output values and/or keys, always 141 end values with the null character (instead of a 142 newline). Use newline instead as a delimiter between 143 key and value. This allows for secure parsing of the 144 output without getting confused e.g. by values that 145 contain line breaks. 146 147--get-colorbool name [stdout-is-tty]:: 148 149 Find the color setting for `name` (e.g. `color.diff`) and output 150 "true" or "false". `stdout-is-tty` should be either "true" or 151 "false", and is taken into account when configuration says 152 "auto". If `stdout-is-tty` is missing, then checks the standard 153 output of the command itself, and exits with status 0 if color 154 is to be used, or exits with status 1 otherwise. 155 When the color setting for `name` is undefined, the command uses 156 `color.ui` as fallback. 157 158--get-color name default:: 159 160 Find the color configured for `name` (e.g. `color.diff.new`) and 161 output it as the ANSI color escape sequence to the standard 162 output. The optional `default` parameter is used instead, if 163 there is no color configured for `name`. 164 165-e:: 166--edit:: 167 Opens an editor to modify the specified config file; either 168 '--system', '--global', or repository (default). 169 170[[FILES]] 171FILES 172----- 173 174If not set explicitly with '--file', there are three files where 175'git-config' will search for configuration options: 176 177$GIT_DIR/config:: 178 Repository specific configuration file. (The filename is 179 of course relative to the repository root, not the working 180 directory.) 181 182~/.gitconfig:: 183 User-specific configuration file. Also called "global" 184 configuration file. 185 186$(prefix)/etc/gitconfig:: 187 System-wide configuration file. 188 189If no further options are given, all reading options will read all of these 190files that are available. If the global or the system-wide configuration 191file are not available they will be ignored. If the repository configuration 192file is not available or readable, 'git-config' will exit with a non-zero 193error code. However, in neither case will an error message be issued. 194 195All writing options will per default write to the repository specific 196configuration file. Note that this also affects options like '--replace-all' 197and '--unset'. *'git-config' will only ever change one file at a time*. 198 199You can override these rules either by command line options or by environment 200variables. The '--global' and the '--system' options will limit the file used 201to the global or system-wide file respectively. The GIT_CONFIG environment 202variable has a similar effect, but you can specify any filename you want. 203 204 205ENVIRONMENT 206----------- 207 208GIT_CONFIG:: 209 Take the configuration from the given file instead of .git/config. 210 Using the "--global" option forces this to ~/.gitconfig. Using the 211 "--system" option forces this to $(prefix)/etc/gitconfig. 212 213See also <<FILES>>. 214 215 216[[EXAMPLES]] 217EXAMPLES 218-------- 219 220Given a .git/config like this: 221 222 # 223 # This is the config file, and 224 # a '#' or ';' character indicates 225 # a comment 226 # 227 228 ; core variables 229 [core] 230 ; Don't trust file modes 231 filemode = false 232 233 ; Our diff algorithm 234 [diff] 235 external = /usr/local/bin/diff-wrapper 236 renames = true 237 238 ; Proxy settings 239 [core] 240 gitproxy="proxy-command" for kernel.org 241 gitproxy=default-proxy ; for all the rest 242 243you can set the filemode to true with 244 245------------ 246% git config core.filemode true 247------------ 248 249The hypothetical proxy command entries actually have a postfix to discern 250what URL they apply to. Here is how to change the entry for kernel.org 251to "ssh". 252 253------------ 254% git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$' 255------------ 256 257This makes sure that only the key/value pair for kernel.org is replaced. 258 259To delete the entry for renames, do 260 261------------ 262% git config --unset diff.renames 263------------ 264 265If you want to delete an entry for a multivar (like core.gitproxy above), 266you have to provide a regex matching the value of exactly one line. 267 268To query the value for a given key, do 269 270------------ 271% git config --get core.filemode 272------------ 273 274or 275 276------------ 277% git config core.filemode 278------------ 279 280or, to query a multivar: 281 282------------ 283% git config --get core.gitproxy "for kernel.org$" 284------------ 285 286If you want to know all the values for a multivar, do: 287 288------------ 289% git config --get-all core.gitproxy 290------------ 291 292If you like to live dangerously, you can replace *all* core.gitproxy by a 293new one with 294 295------------ 296% git config --replace-all core.gitproxy ssh 297------------ 298 299However, if you really only want to replace the line for the default proxy, 300i.e. the one without a "for ..." postfix, do something like this: 301 302------------ 303% git config core.gitproxy ssh '! for ' 304------------ 305 306To actually match only values with an exclamation mark, you have to 307 308------------ 309% git config section.key value '[!]' 310------------ 311 312To add a new proxy, without altering any of the existing ones, use 313 314------------ 315% git config core.gitproxy '"proxy-command" for example.com' 316------------ 317 318An example to use customized color from the configuration in your 319script: 320 321------------ 322#!/bin/sh 323WS=$(git config --get-color color.diff.whitespace "blue reverse") 324RESET=$(git config --get-color "" "reset") 325echo "${WS}your whitespace color or blue reverse${RESET}" 326------------ 327 328include::config.txt[] 329 330 331Author 332------ 333Written by Johannes Schindelin <Johannes.Schindelin@gmx.de> 334 335Documentation 336-------------- 337Documentation by Johannes Schindelin, Petr Baudis and the git-list <git@vger.kernel.org>. 338 339GIT 340--- 341Part of the linkgit:git[1] suite
