  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.
  61

  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
  74--get::
  75        Get the value for a given key (optionally filtered by a regex
  76        matching the value). Returns error code 1 if the key was not
  77        found and error code 2 if multiple key values were found.
  78
  79--get-all::
  80        Like get, but does not fail if the number of values for the key
  81        is not exactly one.
  82
  83--get-regexp::
  84        Like --get-all, but interprets the name as a regular expression.
  85        Also outputs the key names.
  86
  87--global::
  88        For writing options: write to global ~/.gitconfig file rather than
  89        the repository .git/config.
  90+
  91For reading options: read only from global ~/.gitconfig rather than
  92from all available files.
  93+
  94See also <<FILES>>.
  95
  96--system::
  97        For writing options: write to system-wide $(prefix)/etc/gitconfig
  98        rather than the repository .git/config.
  99+
 100For reading options: read only from system-wide $(prefix)/etc/gitconfig
 101rather than from all available files.
 102+
 103See also <<FILES>>.
 104
 105-f config-file::
 106--file config-file::
 107        Use the given config file instead of the one specified by GIT_CONFIG.
 108
 109--remove-section::
 110        Remove the given section from the configuration file.
 111
 112--rename-section::
 113        Rename the given section to a new name.
 114
 115--unset::
 116        Remove the line matching the key from config file.
 117
 118--unset-all::
 119        Remove all lines matching the key from config file.
 120
 121-l::
 122--list::
 123        List all variables set in config file.
 124
 125--bool::
 126        'git-config' will ensure that the output is "true" or "false"
 127
 128--int::
 129        'git-config' will ensure that the output is a simple
 130        decimal number.  An optional value suffix of 'k', 'm', or 'g'
 131        in the config file will cause the value to be multiplied
 132        by 1024, 1048576, or 1073741824 prior to output.
 133
 134--bool-or-int::
 135        'git-config' will ensure that the output matches the format of
 136        either --bool or --int, as described above.
 137
 138-z::
 139--null::
 140        For all options that output values and/or keys, always
 141        end values with the null character (instead of a
 142        newline). Use newline instead as a delimiter between
 143        key and value. This allows for secure parsing of the
 144        output without getting confused e.g. by values that
 145        contain line breaks.
 146
 147--get-colorbool name [stdout-is-tty]::
 148
 149        Find the color setting for `name` (e.g. `color.diff`) and output
 150        "true" or "false".  `stdout-is-tty` should be either "true" or
 151        "false", and is taken into account when configuration says
 152        "auto".  If `stdout-is-tty` is missing, then checks the standard
 153        output of the command itself, and exits with status 0 if color
 154        is to be used, or exits with status 1 otherwise.
 155        When the color setting for `name` is undefined, the command uses
 156        `color.ui` as fallback.
 157
 158--get-color name default::
 159
 160        Find the color configured for `name` (e.g. `color.diff.new`) and
 161        output it as the ANSI color escape sequence to the standard
 162        output.  The optional `default` parameter is used instead, if
 163        there is no color configured for `name`.
 164
 165-e::
 166--edit::
 167        Opens an editor to modify the specified config file; either
 168        '--system', '--global', or repository (default).
 169

 171FILES
 172-----
 173
 174If not set explicitly with '--file', there are three files where
 175'git-config' will search for configuration options:
 176
 177$GIT_DIR/config::
 178        Repository specific configuration file. (The filename is
 179        of course relative to the repository root, not the working
 180        directory.)
 181
 182~/.gitconfig::
 183        User-specific configuration file. Also called "global"
 184        configuration file.
 185
 186$(prefix)/etc/gitconfig::
 187        System-wide configuration file.
 188
 189If no further options are given, all reading options will read all of these
 190files that are available. If the global or the system-wide configuration
 191file are not available they will be ignored. If the repository configuration
 192file is not available or readable, 'git-config' will exit with a non-zero
 193error code. However, in neither case will an error message be issued.
 194
 195All writing options will per default write to the repository specific
 196configuration file. Note that this also affects options like '--replace-all'
 197and '--unset'. *'git-config' will only ever change one file at a time*.
 198
 199You can override these rules either by command line options or by environment
 200variables. The '--global' and the '--system' options will limit the file used
 201to the global or system-wide file respectively. The GIT_CONFIG environment
 202variable has a similar effect, but you can specify any filename you want.
 203
 204
 205ENVIRONMENT
 206-----------
 207
 208GIT_CONFIG::
 209        Take the configuration from the given file instead of .git/config.
 210        Using the "--global" option forces this to ~/.gitconfig. Using the
 211        "--system" option forces this to $(prefix)/etc/gitconfig.

 218--------
 219
 220Given a .git/config like this:
 221
 222        #
 223        # This is the config file, and
 224        # a '#' or ';' character indicates
 225        # a comment
 226        #
 227
 228        ; core variables
 229        [core]
 230                ; Don't trust file modes
 231                filemode = false
 232
 233        ; Our diff algorithm
 234        [diff]
 235                external = /usr/local/bin/diff-wrapper
 236                renames = true
 237
 238        ; Proxy settings
 239        [core]
 240                gitproxy="proxy-command" for kernel.org
 241                gitproxy=default-proxy ; for all the rest
 242
 243you can set the filemode to true with
 244
 245------------
 246% git config core.filemode true
 247------------
 248
 249The hypothetical proxy command entries actually have a postfix to discern
 250what URL they apply to. Here is how to change the entry for kernel.org
 251to "ssh".
 252
 253------------
 254% git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'
 255------------
 256
 257This makes sure that only the key/value pair for kernel.org is replaced.
 258
 259To delete the entry for renames, do
 260
 261------------
 262% git config --unset diff.renames
 263------------
 264
 265If you want to delete an entry for a multivar (like core.gitproxy above),
 266you have to provide a regex matching the value of exactly one line.
 267
 268To query the value for a given key, do
 269
 270------------
 271% git config --get core.filemode
 272------------
 273
 274or
 275
 276------------
 277% git config core.filemode
 278------------
 279
 280or, to query a multivar:
 281
 282------------
 283% git config --get core.gitproxy "for kernel.org$"
 284------------
 285
 286If you want to know all the values for a multivar, do:
 287
 288------------
 289% git config --get-all core.gitproxy
 290------------
 291
 292If you like to live dangerously, you can replace *all* core.gitproxy by a
 293new one with
 294
 295------------
 296% git config --replace-all core.gitproxy ssh
 297------------
 298
 299However, if you really only want to replace the line for the default proxy,
 300i.e. the one without a "for ..." postfix, do something like this:
 301
 302------------
 303% git config core.gitproxy ssh '! for '
 304------------
 305
 306To actually match only values with an exclamation mark, you have to
 307
 308------------
 309% git config section.key value '[!]'
 310------------
 311
 312To add a new proxy, without altering any of the existing ones, use
 313
 314------------
 315% git config core.gitproxy '"proxy-command" for example.com'
 316------------
 317
 318An example to use customized color from the configuration in your
 319script:
 320
 321------------
 322#!/bin/sh
 323WS=$(git config --get-color color.diff.whitespace "blue reverse")
 324RESET=$(git config --get-color "" "reset")
 325echo "${WS}your whitespace color or blue reverse${RESET}"
