  23DESCRIPTION
  24-----------
  25You can query/set/replace/unset options with this command. The name is
  26actually the section and the key separated by a dot, and the value will be
  27escaped.
  28
  29Multiple lines can be added to an option by using the '--add' option.
  30If you want to update or unset an option which can occur on multiple
  31lines, a POSIX regexp `value_regex` needs to be given.  Only the
  32existing values that match the regexp are updated or unset.  If
  33you want to handle the lines that do *not* match the regex, just
  34prepend a single exclamation mark in front (see also <<EXAMPLES>>).
  35
  36The type specifier can be either '--int' or '--bool', which will make
  37'git-config' ensure that the variable(s) are of the given type and
  38convert the value to the canonical form (simple decimal number for int,
  39a "true" or "false" string for bool).  Type specifiers currently only
  40take effect for reading operations.  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.

  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
  77--global::
  78        Use global ~/.gitconfig file rather than the repository .git/config.
  79
  80--system::
  81        Use system-wide $(prefix)/etc/gitconfig rather than the repository
  82        .git/config.
  83
  84--remove-section::
  85        Remove the given section from the configuration file.
  86
  87--rename-section::
  88        Rename the given section to a new name.
  89
  90--unset::
  91        Remove the line matching the key from config file.
  92
  93--unset-all::
  94        Remove all lines matching the key from config file.
  95
  96-l, --list::
  97        List all variables set in config file.
  98
  99--bool::
 100        git-config will ensure that the output is "true" or "false"
 101
 102--int::
 103        git-config will ensure that the output is a simple
 104        decimal number.  An optional value suffix of 'k', 'm', or 'g'
 105        in the config file will cause the value to be multiplied
 106        by 1024, 1048576, or 1073741824 prior to output.
 107
 108
 109ENVIRONMENT
 110-----------
 111
 112GIT_CONFIG::
 113        Take the configuration from the given file instead of .git/config.
 114        Using the "--global" option forces this to ~/.gitconfig.
 115
 116GIT_CONFIG_LOCAL::
 117        Currently the same as $GIT_CONFIG; when Git will support global
 118        configuration files, this will cause it to take the configuration
 119        from the global configuration file in addition to the given file.

 127Given a .git/config like this:
 128
 129        #
 130        # This is the config file, and
 131        # a '#' or ';' character indicates
 132        # a comment
 133        #
 134
 135        ; core variables
 136        [core]
 137                ; Don't trust file modes
 138                filemode = false
 139
 140        ; Our diff algorithm
 141        [diff]
 142                external = "/usr/local/bin/gnu-diff -u"
 143                renames = true
 144
 145        ; Proxy settings
 146        [core]
 147                gitproxy="ssh" for "ssh://kernel.org/"
 148                gitproxy="proxy-command" for kernel.org
 149                gitproxy="myprotocol-command" for "my://"
 150                gitproxy=default-proxy ; for all the rest
 151
 152you can set the filemode to true with
 153
 154------------
 155% git config core.filemode true
 156------------
 157
 158The hypothetical proxy command entries actually have a postfix to discern
 159what URL they apply to. Here is how to change the entry for kernel.org
 160to "ssh".
 161
 162------------
 163% git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'
 164------------
 165
 166This makes sure that only the key/value pair for kernel.org is replaced.
 167
 168To delete the entry for renames, do
 169
 170------------
 171% git config --unset diff.renames
 172------------
 173
 174If you want to delete an entry for a multivar (like core.gitproxy above),
 175you have to provide a regex matching the value of exactly one line.
 176
 177To query the value for a given key, do
 178
 179------------
 180% git config --get core.filemode
 181------------
 182
 183or
 184
 185------------
 186% git config core.filemode
 187------------
 188
 189or, to query a multivar:
 190
 191------------
 192% git config --get core.gitproxy "for kernel.org$"
 193------------
 194
 195If you want to know all the values for a multivar, do:
 196
 197------------
 198% git config --get-all core.gitproxy
 199------------
 200
 201If you like to live dangerous, you can replace *all* core.gitproxy by a
 202new one with
 203
 204------------
 205% git config --replace-all core.gitproxy ssh
 206------------
 207
 208However, if you really only want to replace the line for the default proxy,
 209i.e. the one without a "for ..." postfix, do something like this:
 210
 211------------
 212% git config core.gitproxy ssh '! for '
 213------------
 214
 215To actually match only values with an exclamation mark, you have to
 216
 217------------
 218% git config section.key value '[!]'
 219------------
 220
 221To add a new proxy, without altering any of the existing ones, use
 222
 223------------
 224% git config core.gitproxy '"proxy" for example.com'
 225------------
