The name is 29actually the section and the key separated by a dot, and the value will be 30escaped. 31 32Multiple lines can be added to an option by using the '--add' option. 33If you want to update or unset an option which can occur on multiple 34lines, a POSIX regexp `value_regex` needs to be given. Only the 35existing values that match the regexp are updated or unset. If 36you want to handle the lines that do *not* match the regex, just 37prepend a single exclamation mark in front (see also <<EXAMPLES>>). 38 39The type specifier can be either '--int' or '--bool', which will make 40'git-config' ensure that the variable(s) are of the given type and 41convert the value to the canonical form (simple decimal number for int, 42a "true" or "false" string for bool). If no type specifier is passed, 43no checks or transformations are performed on the value. 44 45The file-option can be one of '--system', '--global' or '--file' 46which specify where the values will be read from or written to. 47The default is to assume the config file of the current repository, 48.git/config unless defined otherwise with GIT_DIR and GIT_CONFIG 49(see <<FILES>>). 50 51This command will fail if: 52 53. The config file is invalid, 54. Can not write to the config file, 55. no section was provided, 56. the section or key is invalid, 57. you try to unset an option which does not exist, 58. you try to unset/set an option for which multiple lines match, or 59. you use '--global' option without $HOME being properly set. 60 61 62OPTIONS 63------- 64 65--replace-all:: 66 Default behavior is to replace at most one line. This replaces 67 all lines matching the key (and optionally the value_regex). 68 69--add:: 70 Adds a new line to the option without altering any existing 71 values. This is the same as providing '^$' as the value_regex. 72 73--get:: 74 Get the value for a given key (optionally filtered by a regex 75 matching the value). Returns error code 1 if the key was not 76 found and error code 2 if multiple key values were found. 77 78--get-all:: 79 Like get, but does not fail if the number of values for the key 80 is not exactly one. 81 82--get-regexp:: 83 Like --get-all, but interprets the name as a regular expression. 84 Also outputs the key names. 85 86--global:: 87 For writing options: write to global ~/.gitconfig file rather than 88 the repository .git/config. 89+ 90For reading options: read only from global ~/.gitconfig rather than 91from all available files. 92+ 93See also <<FILES>>. 94 95--system:: 96 For writing options: write to system-wide $(prefix)/etc/gitconfig 97 rather than the repository .git/config. 98+ 99For reading options: read only from system-wide $(prefix)/etc/gitconfig 100rather than from all available files. 101+ 102See also <<FILES>>. 103 104-f config-file:: 105--file config-file:: 106 Use the given config file instead of the one specified by GIT_CONFIG. 107 108--remove-section:: 109 Remove the given section from the configuration file. 110 111--rename-section:: 112 Rename the given section to a new name. 113 114--unset:: 115 Remove the line matching the key from config file. 116 117--unset-all:: 118 Remove all lines matching the key from config file. 119 120-l:: 121--list:: 122 List all variables set in config file. 123 124--bool:: 125 'git-config' will ensure that the output is "true" or "false" 126 127--int:: 128 'git-config' will ensure that the output is a simple 129 decimal number. An optional value suffix of 'k', 'm', or 'g' 130 in the config file will cause the value to be multiplied 131 by 1024, 1048576, or 1073741824 prior to output. 132 133-z:: 134--null:: 135 For all options that output values and/or keys, always 136 end values with the null character (instead of a 137 newline). Use newline instead as a delimiter between 138 key and value. This allows for secure parsing of the 139 output without getting confused e.g. by values that 140 contain line breaks. 141 142--get-colorbool name [stdout-is-tty]:: 143 144 Find the color setting for `name` (e.g. `color.diff`) and output 145 "true" or "false". `stdout-is-tty` should be either "true" or 146 "false", and is taken into account when configuration says 147 "auto". If `stdout-is-tty` is missing, then checks the standard 148 output of the command itself, and exits with status 0 if color 149 is to be used, or exits with status 1 otherwise. 150 When the color setting for `name` is undefined, the command uses 151 `color.ui` as fallback. 152 153--get-color name default:: 154 155 Find the color configured for `name` (e.g. `color.diff.new`) and 156 output it as the ANSI color escape sequence to the standard 157 output. The optional `default` parameter is used instead, if 158 there is no color configured for `name`. 159 160[[FILES]] 161FILES 162----- 163 164If not set explicitly with '--file', there are three files where 165'git-config' will search for configuration options: 166 167$GIT_DIR/config:: 168 Repository specific configuration file. (The filename is 169 of course relative to the repository root, not the working 170 directory.) 171 172~/.gitconfig:: 173 User-specific configuration file. Also called "global" 174 configuration file. 175 176$(prefix)/etc/gitconfig:: 177 System-wide configuration file. 178 179If no further options are given, all reading options will read all of these 180files that are available. If the global or the system-wide configuration 181file are not available they will be ignored. If the repository configuration 182file is not available or readable, 'git-config' will exit with a non-zero 183error code. However, in neither case will an error message be issued. 184 185All writing options will per default write to the repository specific 186configuration file. Note that this also affects options like '--replace-all' 187and '--unset'. *'git-config' will only ever change one file at a time*. 188 189You can override these rules either by command line options or by environment 190variables. The '--global' and the '--system' options will limit the file used 191to the global or system-wide file respectively. The GIT_CONFIG environment 192variable has a similar effect, but you can specify any filename you want. 193 194 195ENVIRONMENT 196----------- 197 198GIT_CONFIG:: 199 Take the configuration from the given file instead of .git/config. 200 Using the "--global" option forces this to ~/.gitconfig. Using the 201 "--system" option forces this to $(prefix)/etc/gitconfig. 202 203See also <<FILES>>. 204 205 206[[EXAMPLES]] 207EXAMPLES 208-------- 209 210Given a .git/config like this: 211 212 # 213 # This is the config file, and 214 # a '#' or ';' character indicates 215 # a comment 216 # 217 218 ; core variables 219 [core] 220 ; Don't trust file modes 221 filemode = false 222 223 ; Our diff algorithm 224 [diff] 225 external = "/usr/local/bin/gnu-diff -u" 226 renames = true 227 228 ; Proxy settings 229 [core] 230 gitproxy="proxy-command" for kernel.org 231 gitproxy=default-proxy ; for all the rest 232 233you can set the filemode to true with 234 235------------ 236% git config core.filemode true 237------------ 238 239The hypothetical proxy command entries actually have a postfix to discern 240what URL they apply to. Here is how to change the entry for kernel.org 241to "ssh". 242 243------------ 244% git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$' 245------------ 246 247This makes sure that only the key/value pair for kernel.org is replaced. 248 249To delete the entry for renames, do 250 251------------ 252% git config --unset diff.renames 253------------ 254 255If you want to delete an entry for a multivar (like core.gitproxy above), 256you have to provide a regex matching the value of exactly one line. 257 258To query the value for a given key, do 259 260------------ 261% git config --get core.filemode 262------------ 263 264or 265 266------------ 267% git config core.filemode 268------------ 269 270or, to query a multivar: 271 272------------ 273% git config --get core.gitproxy "for kernel.org$" 274------------ 275 276If you want to know all the values for a multivar, do: 277 278------------ 279% git config --get-all core.gitproxy 280------------ 281 282If you like to live dangerous, you can replace *all* core.gitproxy by a 283new one with 284 285------------ 286% git config --replace-all core.gitproxy ssh 287------------ 288 289However, if you really only want to replace the line for the default proxy, 290i.e. the one without a "for ..." postfix, do something like this: 291 292------------ 293% git config core.gitproxy ssh '! for ' 294------------ 295 296To actually match only values with an exclamation mark, you have to 297 298------------ 299% git config section.key value '[!]' 300------------ 301 302To add a new proxy, without altering any of the existing ones, use 303 304------------ 305% git config core.gitproxy '"proxy-command" for example.com' 306------------ 307 308An example to use customized color from the configuration in your 309script: 310 311------------ 312#!/bin/sh 313WS=$(git config --get-color color.diff.whitespace "blue reverse") 314RESET=$(git config --get-color "" "reset") 315echo "${WS}your whitespace color or blue reverse${RESET}" 316------------ 317 318include::config.txt[] 319 320 321Author 322------ 323Written by Johannes Schindelin <Johannes.Schindelin@gmx.de> 324 325Documentation 326-------------- 327Documentation by Johannes Schindelin, Petr Baudis and the git-list <git@vger.kernel.org>. 328 329GIT 330--- 331Part of the linkgit:git[1] suite
