  27DESCRIPTION
  28-----------
  29You can query/set/replace/unset options with this command. 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.

  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        in `--replace-all`.
  74
  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.
  79
  80--get-all::
  81        Like get, but does not fail if the number of values for the key
  82        is not exactly one.
  83
  84--get-regexp::
  85        Like --get-all, but interprets the name as a regular expression.
  86        Also outputs the key names.
  87
  88--global::
  89        For writing options: write to global ~/.gitconfig file rather than
  90        the repository .git/config.
  91+
  92For reading options: read only from global ~/.gitconfig rather than
  93from all available files.
  94+
  95See also <<FILES>>.
  96
  97--system::
  98        For writing options: write to system-wide $(prefix)/etc/gitconfig
  99        rather than the repository .git/config.
 100+
 101For reading options: read only from system-wide $(prefix)/etc/gitconfig
 102rather than from all available files.
 103+
 104See also <<FILES>>.
 105
 106-f config-file::
 107--file config-file::
 108        Use the given config file instead of the one specified by GIT_CONFIG.
 109
 110--remove-section::
 111        Remove the given section from the configuration file.
 112
 113--rename-section::
 114        Rename the given section to a new name.
 115
 116--unset::
 117        Remove the line matching the key from config file.
 118
 119--unset-all::
 120        Remove all lines matching the key from config file.
 121
 122-l::
 123--list::
 124        List all variables set in config file.
 125
 126--bool::
 127        'git-config' will ensure that the output is "true" or "false"
 128
 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.
 134
 135--bool-or-int::
 136        'git-config' will ensure that the output matches the format of
 137        either --bool or --int, as described above.
 138
 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.
 147
 148--get-colorbool name [stdout-is-tty]::
 149
 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.
 158
 159--get-color name [default]::
 160
 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`.
 165
 166-e::
 167--edit::
 168        Opens an editor to modify the specified config file; either
 169        '--system', '--global', or repository (default).
 170
 171[[FILES]]
 172FILES
 173-----
 174
 175If not set explicitly with '--file', there are three files where
 176'git-config' will search for configuration options:
 177
 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.)
 182
 183~/.gitconfig::
 184        User-specific configuration file. Also called "global"
 185        configuration file.
 186
 187$(prefix)/etc/gitconfig::
 188        System-wide configuration file.
 189
 190If no further options are given, all reading options will read all of these
 191files that are available. If the global or the system-wide configuration
 192file are not available they will be ignored. If the repository configuration
 193file is not available or readable, 'git-config' will exit with a non-zero
 194error code. However, in neither case will an error message be issued.
 195
 196All writing options will per default write to the repository specific
 197configuration file. Note that this also affects options like '--replace-all'
 198and '--unset'. *'git-config' will only ever change one file at a time*.
 199
 200You can override these rules either by command line options or by environment
 201variables. The '--global' and the '--system' options will limit the file used
 202to the global or system-wide file respectively. The GIT_CONFIG environment
 203variable has a similar effect, but you can specify any filename you want.
 204
 205
 206ENVIRONMENT
 207-----------
 208
 209GIT_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.

 219--------
 220
 221Given a .git/config like this:
 222
 223        #
 224        # This is the config file, and
 225        # a '#' or ';' character indicates
 226        # a comment
 227        #
 228
 229        ; core variables
 230        [core]
 231                ; Don't trust file modes
 232                filemode = false
 233
 234        ; Our diff algorithm
 235        [diff]
 236                external = /usr/local/bin/diff-wrapper
 237                renames = true
 238
 239        ; Proxy settings
 240        [core]
 241                gitproxy="proxy-command" for kernel.org
 242                gitproxy=default-proxy ; for all the rest
 243
 244you can set the filemode to true with
 245
 246------------
 247% git config core.filemode true
 248------------
 249
 250The hypothetical proxy command entries actually have a postfix to discern
 251what URL they apply to. Here is how to change the entry for kernel.org
 252to "ssh".
 253
 254------------
 255% git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'
 256------------
 257
 258This makes sure that only the key/value pair for kernel.org is replaced.
 259
 260To delete the entry for renames, do
 261
 262------------
 263% git config --unset diff.renames
 264------------
 265
 266If you want to delete an entry for a multivar (like core.gitproxy above),
 267you have to provide a regex matching the value of exactly one line.
 268
 269To query the value for a given key, do
 270
 271------------
 272% git config --get core.filemode
 273------------
 274
 275or
 276
 277------------
 278% git config core.filemode
 279------------
 280
 281or, to query a multivar:
 282
 283------------
 284% git config --get core.gitproxy "for kernel.org$"
 285------------
 286
 287If you want to know all the values for a multivar, do:
 288
 289------------
 290% git config --get-all core.gitproxy
 291------------
 292
 293If you like to live dangerously, you can replace *all* core.gitproxy by a
 294new one with
 295
 296------------
 297% git config --replace-all core.gitproxy ssh
 298------------
 299
 300However, if you really only want to replace the line for the default proxy,
 301i.e. the one without a "for ..." postfix, do something like this:
 302
 303------------
 304% git config core.gitproxy ssh '! for '
 305------------
 306
 307To actually match only values with an exclamation mark, you have to
 308
 309------------
 310% git config section.key value '[!]'
 311------------
 312
 313To add a new proxy, without altering any of the existing ones, use
 314
 315------------
 316% git config core.gitproxy '"proxy-command" for example.com'
 317------------
 318
 319An example to use customized color from the configuration in your
 320script:
 321
 322------------
 323#!/bin/sh
 324WS=$(git config --get-color color.diff.whitespace "blue reverse")
 325RESET=$(git config --get-color "" "reset")
 326echo "${WS}your whitespace color or blue reverse${RESET}"
