  21DESCRIPTION
  22-----------
  23You can query/set/replace/unset options with this command. The name is
  24actually the section and the key separated by a dot, and the value will be
  25escaped.
  26
  27Multiple lines can be added to an option by using the '--add' option.
  28If you want to update or unset an option which can occur on multiple
  29lines, a POSIX regexp `value_regex` needs to be given.  Only the
  30existing values that match the regexp are updated or unset.  If
  31you want to handle the lines that do *not* match the regex, just
  32prepend a single exclamation mark in front (see EXAMPLES).
  33
  34The type specifier can be either '--int' or '--bool', which will make
  35'git-config' ensure that the variable(s) are of the given type and
  36convert the value to the canonical form (simple decimal number for int,
  37a "true" or "false" string for bool). If no type specifier is passed,
  38no checks or transformations are performed on the value.
  39
  40This command will fail if:
  41
  42. The .git/config file is invalid,
  43. Can not write to .git/config,
  44. no section was provided,
  45. the section or key is invalid,
  46. you try to unset an option which does not exist,
  47. you try to unset/set an option for which multiple lines match, or
  48. you use --global option without $HOME being properly set.

  51OPTIONS
  52-------
  53
  54--replace-all::
  55        Default behavior is to replace at most one line. This replaces
  56        all lines matching the key (and optionally the value_regex).
  57
  58--add::
  59        Adds a new line to the option without altering any existing
  60        values.  This is the same as providing '^$' as the value_regex.
  61
  62--get::
  63        Get the value for a given key (optionally filtered by a regex
  64        matching the value). Returns error code 1 if the key was not
  65        found and error code 2 if multiple key values were found.
  66
  67--get-all::
  68        Like get, but does not fail if the number of values for the key
  69        is not exactly one.
  70
  71--get-regexp::
  72        Like --get-all, but interprets the name as a regular expression.
  73
  74--global::
  75        Use global ~/.gitconfig file rather than the repository .git/config.
  76
  77--unset::
  78        Remove the line matching the key from config file.
  79
  80--unset-all::
  81        Remove all matching lines from config file.
  82
  83-l, --list::
  84        List all variables set in config file.
  85
  86--bool::
  87        git-config will ensure that the output is "true" or "false"
  88
  89--int::
  90        git-config will ensure that the output is a simple
  91        decimal number.  An optional value suffix of 'k', 'm', or 'g'
  92        in the config file will cause the value to be multiplied
  93        by 1024, 1048576, or 1073741824 prior to output.
  94
  95
  96ENVIRONMENT
  97-----------
  98
  99GIT_CONFIG::
 100        Take the configuration from the given file instead of .git/config.
 101        Using the "--global" option forces this to ~/.gitconfig.
 102
 103GIT_CONFIG_LOCAL::
 104        Currently the same as $GIT_CONFIG; when Git will support global
 105        configuration files, this will cause it to take the configuration
 106        from the global configuration file in addition to the given file.
 107
 108
 109EXAMPLE
 110-------
 111
 112Given a .git/config like this:
 113
 114        #
 115        # This is the config file, and
 116        # a '#' or ';' character indicates
 117        # a comment
 118        #
 119
 120        ; core variables
 121        [core]
 122                ; Don't trust file modes
 123                filemode = false
 124
 125        ; Our diff algorithm
 126        [diff]
 127                external = "/usr/local/bin/gnu-diff -u"
 128                renames = true
 129
 130        ; Proxy settings
 131        [core]
 132                gitproxy="ssh" for "ssh://kernel.org/"
 133                gitproxy="proxy-command" for kernel.org
 134                gitproxy="myprotocol-command" for "my://"
 135                gitproxy=default-proxy ; for all the rest
 136
 137you can set the filemode to true with
 138
 139------------
 140% git config core.filemode true
 141------------
 142
 143The hypothetical proxy command entries actually have a postfix to discern
 144what URL they apply to. Here is how to change the entry for kernel.org
 145to "ssh".
 146
 147------------
 148% git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'
 149------------
 150
 151This makes sure that only the key/value pair for kernel.org is replaced.
 152
 153To delete the entry for renames, do
 154
 155------------
 156% git config --unset diff.renames
 157------------
 158
 159If you want to delete an entry for a multivar (like core.gitproxy above),
 160you have to provide a regex matching the value of exactly one line.
 161
 162To query the value for a given key, do
 163
 164------------
 165% git config --get core.filemode
 166------------
 167
 168or
 169
 170------------
 171% git config core.filemode
 172------------
 173
 174or, to query a multivar:
 175
 176------------
 177% git config --get core.gitproxy "for kernel.org$"
 178------------
 179
 180If you want to know all the values for a multivar, do:
 181
 182------------
 183% git config --get-all core.gitproxy
 184------------
 185
 186If you like to live dangerous, you can replace *all* core.gitproxy by a
 187new one with
 188
 189------------
 190% git config --replace-all core.gitproxy ssh
 191------------
 192
 193However, if you really only want to replace the line for the default proxy,
 194i.e. the one without a "for ..." postfix, do something like this:
 195
 196------------
 197% git config core.gitproxy ssh '! for '
 198------------
 199
 200To actually match only values with an exclamation mark, you have to
 201
 202------------
 203% git config section.key value '[!]'
 204------------
 205
 206To add a new proxy, without altering any of the existing ones, use
 207
 208------------
 209% git config core.gitproxy '"proxy" for example.com'
 210------------
