  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.

  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--bool-or-int::
 134        'git-config' will ensure that the output matches the format of
 135        either --bool or --int, as described above.
 136
 137-z::
 138--null::
 139        For all options that output values and/or keys, always
 140        end values with the null character (instead of a
 141        newline). Use newline instead as a delimiter between
 142        key and value. This allows for secure parsing of the
 143        output without getting confused e.g. by values that
 144        contain line breaks.
 145
 146--get-colorbool name [stdout-is-tty]::
 147
 148        Find the color setting for `name` (e.g. `color.diff`) and output
 149        "true" or "false".  `stdout-is-tty` should be either "true" or
 150        "false", and is taken into account when configuration says
 151        "auto".  If `stdout-is-tty` is missing, then checks the standard
 152        output of the command itself, and exits with status 0 if color
 153        is to be used, or exits with status 1 otherwise.
 154        When the color setting for `name` is undefined, the command uses
 155        `color.ui` as fallback.
 156
 157--get-color name default::
 158
 159        Find the color configured for `name` (e.g. `color.diff.new`) and
 160        output it as the ANSI color escape sequence to the standard
 161        output.  The optional `default` parameter is used instead, if
 162        there is no color configured for `name`.
 163
 164[[FILES]]
 165FILES
 166-----
 167
 168If not set explicitly with '--file', there are three files where
 169'git-config' will search for configuration options:
 170
 171$GIT_DIR/config::
 172        Repository specific configuration file. (The filename is
 173        of course relative to the repository root, not the working
 174        directory.)
 175
 176~/.gitconfig::
 177        User-specific configuration file. Also called "global"
 178        configuration file.
 179
 180$(prefix)/etc/gitconfig::
 181        System-wide configuration file.
 182
 183If no further options are given, all reading options will read all of these
 184files that are available. If the global or the system-wide configuration
 185file are not available they will be ignored. If the repository configuration
 186file is not available or readable, 'git-config' will exit with a non-zero
 187error code. However, in neither case will an error message be issued.
 188
 189All writing options will per default write to the repository specific
 190configuration file. Note that this also affects options like '--replace-all'
 191and '--unset'. *'git-config' will only ever change one file at a time*.
 192
 193You can override these rules either by command line options or by environment
 194variables. The '--global' and the '--system' options will limit the file used
 195to the global or system-wide file respectively. The GIT_CONFIG environment
 196variable has a similar effect, but you can specify any filename you want.
 197
 198
 199ENVIRONMENT
 200-----------
 201
 202GIT_CONFIG::
 203        Take the configuration from the given file instead of .git/config.
 204        Using the "--global" option forces this to ~/.gitconfig. Using the
 205        "--system" option forces this to $(prefix)/etc/gitconfig.

 210[[EXAMPLES]]
 211EXAMPLES
 212--------
 213
 214Given a .git/config like this:
 215
 216        #
 217        # This is the config file, and
 218        # a '#' or ';' character indicates
 219        # a comment
 220        #
 221
 222        ; core variables
 223        [core]
 224                ; Don't trust file modes
 225                filemode = false
 226
 227        ; Our diff algorithm
 228        [diff]
 229                external = /usr/local/bin/diff-wrapper
 230                renames = true
 231
 232        ; Proxy settings
 233        [core]
 234                gitproxy="proxy-command" for kernel.org
 235                gitproxy=default-proxy ; for all the rest
 236
 237you can set the filemode to true with
 238
 239------------
 240% git config core.filemode true
 241------------
 242
 243The hypothetical proxy command entries actually have a postfix to discern
 244what URL they apply to. Here is how to change the entry for kernel.org
 245to "ssh".
 246
 247------------
 248% git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'
 249------------
 250
 251This makes sure that only the key/value pair for kernel.org is replaced.
 252
 253To delete the entry for renames, do
 254
 255------------
 256% git config --unset diff.renames
 257------------
 258
 259If you want to delete an entry for a multivar (like core.gitproxy above),
 260you have to provide a regex matching the value of exactly one line.
 261
 262To query the value for a given key, do
 263
 264------------
 265% git config --get core.filemode
 266------------
 267
 268or
 269
 270------------
 271% git config core.filemode
 272------------
 273
 274or, to query a multivar:
 275
 276------------
 277% git config --get core.gitproxy "for kernel.org$"
 278------------
 279
 280If you want to know all the values for a multivar, do:
 281
 282------------
 283% git config --get-all core.gitproxy
 284------------
 285
 286If you like to live dangerously, you can replace *all* core.gitproxy by a
 287new one with
 288
 289------------
 290% git config --replace-all core.gitproxy ssh
 291------------
 292
 293However, if you really only want to replace the line for the default proxy,
 294i.e. the one without a "for ..." postfix, do something like this:
 295
 296------------
 297% git config core.gitproxy ssh '! for '
 298------------
 299
 300To actually match only values with an exclamation mark, you have to
 301
 302------------
 303% git config section.key value '[!]'
 304------------
 305
 306To add a new proxy, without altering any of the existing ones, use
 307
 308------------
 309% git config core.gitproxy '"proxy-command" for example.com'
 310------------
 311
 312An example to use customized color from the configuration in your
 313script:
 314
 315------------
 316#!/bin/sh
 317WS=$(git config --get-color color.diff.whitespace "blue reverse")
 318RESET=$(git config --get-color "" "reset")
 319echo "${WS}your whitespace color or blue reverse${RESET}"
