  24DESCRIPTION
  25-----------
  26You can query/set/replace/unset options with this command. The name is
  27actually the section and the key separated by a dot, and the value will be
  28escaped.
  29
  30Multiple lines can be added to an option by using the '--add' option.
  31If you want to update or unset an option which can occur on multiple
  32lines, a POSIX regexp `value_regex` needs to be given.  Only the
  33existing values that match the regexp are updated or unset.  If
  34you want to handle the lines that do *not* match the regex, just
  35prepend a single exclamation mark in front (see also <<EXAMPLES>>).
  36
  37The type specifier can be either '--int' or '--bool', which will make
  38'git-config' ensure that the variable(s) are of the given type and
  39convert the value to the canonical form (simple decimal number for int,
  40a "true" or "false" string for bool).  If no type specifier is passed,
  41no checks or transformations are performed on the value.
  42
  43This command will fail if:
  44
  45. The .git/config file is invalid,
  46. Can not write to .git/config,
  47. no section was provided,
  48. the section or key is invalid,
  49. you try to unset an option which does not exist,
  50. you try to unset/set an option for which multiple lines match, or
  51. you use '--global' option without $HOME being properly set.
  52
  53
  54OPTIONS
  55-------
  56
  57--replace-all::
  58        Default behavior is to replace at most one line. This replaces
  59        all lines matching the key (and optionally the value_regex).
  60
  61--add::
  62        Adds a new line to the option without altering any existing
  63        values.  This is the same as providing '^$' as the value_regex.
  64
  65--get::
  66        Get the value for a given key (optionally filtered by a regex
  67        matching the value). Returns error code 1 if the key was not
  68        found and error code 2 if multiple key values were found.
  69
  70--get-all::
  71        Like get, but does not fail if the number of values for the key
  72        is not exactly one.
  73
  74--get-regexp::
  75        Like --get-all, but interprets the name as a regular expression.
  76        Also outputs the key names.
  77
  78--global::
  79        For writing options: write to global ~/.gitconfig file rather than
  80        the repository .git/config.
  81+
  82For reading options: read only from global ~/.gitconfig rather than
  83from all available files.
  84+
  85See also <<FILES>>.
  86
  87--system::
  88        For writing options: write to system-wide $(prefix)/etc/gitconfig
  89        rather than the repository .git/config.
  90+
  91For reading options: read only from system-wide $(prefix)/etc/gitconfig
  92rather than from all available files.
  93+
  94See also <<FILES>>.
  95
  96--remove-section::
  97        Remove the given section from the configuration file.
  98
  99--rename-section::
 100        Rename the given section to a new name.
 101
 102--unset::
 103        Remove the line matching the key from config file.
 104
 105--unset-all::
 106        Remove all lines matching the key from config file.
 107
 108-l, --list::
 109        List all variables set in config file.
 110
 111--bool::
 112        git-config will ensure that the output is "true" or "false"
 113
 114--int::
 115        git-config will ensure that the output is a simple
 116        decimal number.  An optional value suffix of 'k', 'm', or 'g'
 117        in the config file will cause the value to be multiplied
 118        by 1024, 1048576, or 1073741824 prior to output.
 119
 120-z, --null::
 121        For all options that output values and/or keys, always
 122        end values with with the null character (instead of a
 123        newline). Use newline instead as a delimiter between
 124        key and value. This allows for secure parsing of the
 125        output without getting confused e.g. by values that
 126        contain line breaks.

 130FILES
 131-----
 132
 133There are three files where git-config will search for configuration
 134options:
 135
 136.git/config::
 137        Repository specific configuration file. (The filename is
 138        of course relative to the repository root, not the working
 139        directory.)
 140
 141~/.gitconfig::
 142        User-specific configuration file. Also called "global"
 143        configuration file.
 144
 145$(prefix)/etc/gitconfig::
 146        System-wide configuration file.
 147
 148If no further options are given, all reading options will read all of these
 149files that are available. If the global or the system-wide configuration
 150file are not available they will be ignored. If the repository configuration
 151file is not available or readable, git-config will exit with a non-zero
 152error code. However, in neither case will an error message be issued.
 153
 154All writing options will per default write to the repository specific
 155configuration file. Note that this also affects options like '--replace-all'
 156and '--unset'. *git-config will only ever change one file at a time*.
 157
 158You can override these rules either by command line options or by environment
 159variables. The '--global' and the '--system' options will limit the file used
 160to the global or system-wide file respectively. The GIT_CONFIG environment
 161variable has a similar effect, but you can specify any filename you want.
 162
 163The GIT_CONFIG_LOCAL environment variable on the other hand only changes
 164the name used instead of the repository configuration file. The global and
 165the system-wide configuration files will still be read. (For writing options
 166this will obviously result in the same behavior as using GIT_CONFIG.)
 167
 168
 169ENVIRONMENT
 170-----------
 171
 172GIT_CONFIG::
 173        Take the configuration from the given file instead of .git/config.
 174        Using the "--global" option forces this to ~/.gitconfig. Using the
 175        "--system" option forces this to $(prefix)/etc/gitconfig.
 176
 177GIT_CONFIG_LOCAL::
 178        Take the configuration from the given file instead if .git/config.
 179        Still read the global and the system-wide configuration files, though.
 180
 181See also <<FILES>>.

 185EXAMPLES
 186--------
 187
 188Given a .git/config like this:
 189
 190        #
 191        # This is the config file, and
 192        # a '#' or ';' character indicates
 193        # a comment
 194        #
 195
 196        ; core variables
 197        [core]
 198                ; Don't trust file modes
 199                filemode = false
 200
 201        ; Our diff algorithm
 202        [diff]
 203                external = "/usr/local/bin/gnu-diff -u"
 204                renames = true
 205
 206        ; Proxy settings
 207        [core]
 208                gitproxy="ssh" for "ssh://kernel.org/"
 209                gitproxy="proxy-command" for kernel.org
 210                gitproxy="myprotocol-command" for "my://"
 211                gitproxy=default-proxy ; for all the rest
 212
 213you can set the filemode to true with
 214
 215------------
 216% git config core.filemode true
 217------------
 218
 219The hypothetical proxy command entries actually have a postfix to discern
 220what URL they apply to. Here is how to change the entry for kernel.org
 221to "ssh".
 222
 223------------
 224% git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'
 225------------
 226
 227This makes sure that only the key/value pair for kernel.org is replaced.
 228
 229To delete the entry for renames, do
 230
 231------------
 232% git config --unset diff.renames
 233------------
 234
 235If you want to delete an entry for a multivar (like core.gitproxy above),
 236you have to provide a regex matching the value of exactly one line.
 237
 238To query the value for a given key, do
 239
 240------------
 241% git config --get core.filemode
 242------------
 243
 244or
 245
 246------------
 247% git config core.filemode
 248------------
 249
 250or, to query a multivar:
 251
 252------------
 253% git config --get core.gitproxy "for kernel.org$"
 254------------
 255
 256If you want to know all the values for a multivar, do:
 257
 258------------
 259% git config --get-all core.gitproxy
 260------------
 261
 262If you like to live dangerous, you can replace *all* core.gitproxy by a
 263new one with
 264
 265------------
 266% git config --replace-all core.gitproxy ssh
 267------------
 268
 269However, if you really only want to replace the line for the default proxy,
 270i.e. the one without a "for ..." postfix, do something like this:
 271
 272------------
 273% git config core.gitproxy ssh '! for '
 274------------
 275
 276To actually match only values with an exclamation mark, you have to
 277
 278------------
 279% git config section.key value '[!]'
 280------------
 281
 282To add a new proxy, without altering any of the existing ones, use
 283
 284------------
 285% git config core.gitproxy '"proxy" for example.com'
 286------------
