  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', to 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), or '--path', which does some
  44path expansion (see '--path' below).  If no type specifier is passed, no
  45checks or transformations are performed on the value.
  46
  47The file-option can be one of '--system', '--global' or '--file'
  48which specify where the values will be read from or written to.
  49The default is to assume the config file of the current repository,
  50.git/config unless defined otherwise with GIT_DIR and GIT_CONFIG
  51(see <<FILES>>).
  52
  53This command will fail if:
  54
  55. The config file is invalid,
  56. Can not write to the config file,
  57. no section was provided,
  58. the section or key is invalid,
  59. you try to unset an option which does not exist,
  60. you try to unset/set an option for which multiple lines match, or
  61. you use '--global' option without $HOME being properly set.
  62
  63
  64OPTIONS
  65-------
  66
  67--replace-all::
  68        Default behavior is to replace at most one line. This replaces
  69        all lines matching the key (and optionally the value_regex).
  70
  71--add::
  72        Adds a new line to the option without altering any existing
  73        values.  This is the same as providing '^$' as the value_regex
  74        in `--replace-all`.
  75
  76--get::
  77        Get the value for a given key (optionally filtered by a regex
  78        matching the value). Returns error code 1 if the key was not
  79        found and error code 2 if multiple key values were found.
  80
  81--get-all::
  82        Like get, but does not fail if the number of values for the key
  83        is not exactly one.
  84
  85--get-regexp::
  86        Like --get-all, but interprets the name as a regular expression.
  87        Also outputs the key names.
  88
  89--global::
  90        For writing options: write to global ~/.gitconfig file rather than
  91        the repository .git/config.
  92+
  93For reading options: read only from global ~/.gitconfig rather than
  94from all available files.
  95+
  96See also <<FILES>>.
  97
  98--system::
  99        For writing options: write to system-wide $(prefix)/etc/gitconfig
 100        rather than the repository .git/config.
 101+
 102For reading options: read only from system-wide $(prefix)/etc/gitconfig
 103rather than from all available files.
 104+
 105See also <<FILES>>.
 106
 107-f config-file::
 108--file config-file::
 109        Use the given config file instead of the one specified by GIT_CONFIG.
 110
 111--remove-section::
 112        Remove the given section from the configuration file.
 113
 114--rename-section::
 115        Rename the given section to a new name.
 116
 117--unset::
 118        Remove the line matching the key from config file.
 119
 120--unset-all::
 121        Remove all lines matching the key from config file.
 122
 123-l::
 124--list::
 125        List all variables set in config file.
 126
 127--bool::
 128        'git config' will ensure that the output is "true" or "false"
 129
 130--int::
 131        'git config' will ensure that the output is a simple
 132        decimal number.  An optional value suffix of 'k', 'm', or 'g'
 133        in the config file will cause the value to be multiplied
 134        by 1024, 1048576, or 1073741824 prior to output.
 135
 136--bool-or-int::
 137        'git config' will ensure that the output matches the format of
 138        either --bool or --int, as described above.
 139
 140--path::
 141        'git-config' will expand leading '{tilde}' to the value of
 142        '$HOME', and '{tilde}user' to the home directory for the
 143        specified user.  This option has no effect when setting the
 144        value (but you can use 'git config bla {tilde}/' from the
 145        command line to let your shell do the expansion).
 146
 147-z::
 148--null::
 149        For all options that output values and/or keys, always
 150        end values with the null character (instead of a
 151        newline). Use newline instead as a delimiter between
 152        key and value. This allows for secure parsing of the
 153        output without getting confused e.g. by values that
 154        contain line breaks.
 155
 156--get-colorbool name [stdout-is-tty]::
 157
 158        Find the color setting for `name` (e.g. `color.diff`) and output
 159        "true" or "false".  `stdout-is-tty` should be either "true" or
 160        "false", and is taken into account when configuration says
 161        "auto".  If `stdout-is-tty` is missing, then checks the standard
 162        output of the command itself, and exits with status 0 if color
 163        is to be used, or exits with status 1 otherwise.
 164        When the color setting for `name` is undefined, the command uses
 165        `color.ui` as fallback.
 166
 167--get-color name [default]::
 168
 169        Find the color configured for `name` (e.g. `color.diff.new`) and
 170        output it as the ANSI color escape sequence to the standard
 171        output.  The optional `default` parameter is used instead, if
 172        there is no color configured for `name`.
 173
 174-e::
 175--edit::
 176        Opens an editor to modify the specified config file; either
 177        '--system', '--global', or repository (default).
 178
 179[[FILES]]
 180FILES
 181-----
 182
 183If not set explicitly with '--file', there are three files where
 184'git config' will search for configuration options:
 185
 186$GIT_DIR/config::
 187        Repository specific configuration file. (The filename is
 188        of course relative to the repository root, not the working
 189        directory.)
 190
 191~/.gitconfig::
 192        User-specific configuration file. Also called "global"
 193        configuration file.
 194
 195$(prefix)/etc/gitconfig::
 196        System-wide configuration file.
 197
 198If no further options are given, all reading options will read all of these
 199files that are available. If the global or the system-wide configuration
 200file are not available they will be ignored. If the repository configuration
 201file is not available or readable, 'git config' will exit with a non-zero
 202error code. However, in neither case will an error message be issued.
 203
 204All writing options will per default write to the repository specific
 205configuration file. Note that this also affects options like '--replace-all'
 206and '--unset'. *'git config' will only ever change one file at a time*.
 207
 208You can override these rules either by command line options or by environment
 209variables. The '--global' and the '--system' options will limit the file used
 210to the global or system-wide file respectively. The GIT_CONFIG environment
 211variable has a similar effect, but you can specify any filename you want.
 212
 213
 214ENVIRONMENT
 215-----------
 216
 217GIT_CONFIG::
 218        Take the configuration from the given file instead of .git/config.
 219        Using the "--global" option forces this to ~/.gitconfig. Using the
 220        "--system" option forces this to $(prefix)/etc/gitconfig.

 227--------
 228
 229Given a .git/config like this:
 230
 231        #
 232        # This is the config file, and
 233        # a '#' or ';' character indicates
 234        # a comment
 235        #
 236
 237        ; core variables
 238        [core]
 239                ; Don't trust file modes
 240                filemode = false
 241
 242        ; Our diff algorithm
 243        [diff]
 244                external = /usr/local/bin/diff-wrapper
 245                renames = true
 246
 247        ; Proxy settings
 248        [core]
 249                gitproxy="proxy-command" for kernel.org
 250                gitproxy=default-proxy ; for all the rest
 251
 252you can set the filemode to true with
 253
 254------------
 255% git config core.filemode true
 256------------
 257
 258The hypothetical proxy command entries actually have a postfix to discern
 259what URL they apply to. Here is how to change the entry for kernel.org
 260to "ssh".
 261
 262------------
 263% git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'
 264------------
 265
 266This makes sure that only the key/value pair for kernel.org is replaced.
 267
 268To delete the entry for renames, do
 269
 270------------
 271% git config --unset diff.renames
 272------------
 273
 274If you want to delete an entry for a multivar (like core.gitproxy above),
 275you have to provide a regex matching the value of exactly one line.
 276
 277To query the value for a given key, do
 278
 279------------
 280% git config --get core.filemode
 281------------
 282
 283or
 284
 285------------
 286% git config core.filemode
 287------------
 288
 289or, to query a multivar:
 290
 291------------
 292% git config --get core.gitproxy "for kernel.org$"
 293------------
 294
 295If you want to know all the values for a multivar, do:
 296
 297------------
 298% git config --get-all core.gitproxy
 299------------
 300
 301If you like to live dangerously, you can replace *all* core.gitproxy by a
 302new one with
 303
 304------------
 305% git config --replace-all core.gitproxy ssh
 306------------
 307
 308However, if you really only want to replace the line for the default proxy,
 309i.e. the one without a "for ..." postfix, do something like this:
 310
 311------------
 312% git config core.gitproxy ssh '! for '
 313------------
 314
 315To actually match only values with an exclamation mark, you have to
 316
 317------------
 318% git config section.key value '[!]'
 319------------
 320
 321To add a new proxy, without altering any of the existing ones, use
 322
 323------------
 324% git config core.gitproxy '"proxy-command" for example.com'
 325------------
 326
 327An example to use customized color from the configuration in your
 328script:
 329
 330------------
 331#!/bin/sh
 332WS=$(git config --get-color color.diff.whitespace "blue reverse")
 333RESET=$(git config --get-color "" "reset")
 334echo "${WS}your whitespace color or blue reverse${RESET}"
