  26DESCRIPTION
  27-----------
  28You can query/set/replace/unset options with this command. 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.

  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`.

 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.

 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/diff-wrapper
 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 dangerously, 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}"
