  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 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). If no type specifier is passed,
  40no checks or transformations are performed on the value.
  41
  42This command will fail if:
  43
  44. The .git/config file is invalid,
  45. Can not write to .git/config,
  46. no section was provided,
  47. the section or key is invalid,
  48. you try to unset an option which does not exist,
  49. you try to unset/set an option for which multiple lines match, or
  50. you use --global option without $HOME being properly set.

  53OPTIONS
  54-------
  55
  56--replace-all::
  57        Default behavior is to replace at most one line. This replaces
  58        all lines matching the key (and optionally the value_regex).
  59
  60--add::
  61        Adds a new line to the option without altering any existing
  62        values.  This is the same as providing '^$' as the value_regex.
  63
  64--get::
  65        Get the value for a given key (optionally filtered by a regex
  66        matching the value). Returns error code 1 if the key was not
  67        found and error code 2 if multiple key values were found.
  68
  69--get-all::
  70        Like get, but does not fail if the number of values for the key
  71        is not exactly one.
  72
  73--get-regexp::
  74        Like --get-all, but interprets the name as a regular expression.
  75
  76--global::
  77        Use global ~/.gitconfig file rather than the repository .git/config.
  78
  79--system::
  80        Use system-wide $(prefix)/etc/gitconfig rather than the repository
  81        .git/config.
  82
  83--remove-section::
  84        Remove the given section from the configuration file.
  85
  86--rename-section::
  87        Rename the given section to a new name.
  88
  89--unset::
  90        Remove the line matching the key from config file.
  91
  92--unset-all::
  93        Remove all lines matching the key from config file.
  94
  95-l, --list::
  96        List all variables set in config file.
  97
  98--bool::
  99        git-config will ensure that the output is "true" or "false"
 100
 101--int::
 102        git-config will ensure that the output is a simple
 103        decimal number.  An optional value suffix of 'k', 'm', or 'g'
 104        in the config file will cause the value to be multiplied
 105        by 1024, 1048576, or 1073741824 prior to output.
 106
 107
 108ENVIRONMENT
 109-----------
 110
 111GIT_CONFIG::
 112        Take the configuration from the given file instead of .git/config.
 113        Using the "--global" option forces this to ~/.gitconfig.
 114
 115GIT_CONFIG_LOCAL::
 116        Currently the same as $GIT_CONFIG; when Git will support global
 117        configuration files, this will cause it to take the configuration
 118        from the global configuration file in addition to the given file.
 119

 121EXAMPLE
 122-------
 123
 124Given a .git/config like this:
 125
 126        #
 127        # This is the config file, and
 128        # a '#' or ';' character indicates
 129        # a comment
 130        #
 131
 132        ; core variables
 133        [core]
 134                ; Don't trust file modes
 135                filemode = false
 136
 137        ; Our diff algorithm
 138        [diff]
 139                external = "/usr/local/bin/gnu-diff -u"
 140                renames = true
 141
 142        ; Proxy settings
 143        [core]
 144                gitproxy="ssh" for "ssh://kernel.org/"
 145                gitproxy="proxy-command" for kernel.org
 146                gitproxy="myprotocol-command" for "my://"
 147                gitproxy=default-proxy ; for all the rest
 148
 149you can set the filemode to true with
 150
 151------------
 152% git config core.filemode true
 153------------
 154
 155The hypothetical proxy command entries actually have a postfix to discern
 156what URL they apply to. Here is how to change the entry for kernel.org
 157to "ssh".
 158
 159------------
 160% git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'
 161------------
 162
 163This makes sure that only the key/value pair for kernel.org is replaced.
 164
 165To delete the entry for renames, do
 166
 167------------
 168% git config --unset diff.renames
 169------------
 170
 171If you want to delete an entry for a multivar (like core.gitproxy above),
 172you have to provide a regex matching the value of exactly one line.
 173
 174To query the value for a given key, do
 175
 176------------
 177% git config --get core.filemode
 178------------
 179
 180or
 181
 182------------
 183% git config core.filemode
 184------------
 185
 186or, to query a multivar:
 187
 188------------
 189% git config --get core.gitproxy "for kernel.org$"
 190------------
 191
 192If you want to know all the values for a multivar, do:
 193
 194------------
 195% git config --get-all core.gitproxy
 196------------
 197
 198If you like to live dangerous, you can replace *all* core.gitproxy by a
 199new one with
 200
 201------------
 202% git config --replace-all core.gitproxy ssh
 203------------
 204
 205However, if you really only want to replace the line for the default proxy,
 206i.e. the one without a "for ..." postfix, do something like this:
 207
 208------------
 209% git config core.gitproxy ssh '! for '
 210------------
 211
 212To actually match only values with an exclamation mark, you have to
 213
 214------------
 215% git config section.key value '[!]'
 216------------
 217
 218To add a new proxy, without altering any of the existing ones, use
 219
 220------------
 221% git config core.gitproxy '"proxy" for example.com'
 222------------
