+DESCRIPTION
+-----------
+You can query/set/replace/unset options with this command. The name is
+actually the section and the key separated by a dot, and the value will be
+escaped.
+
+Multiple lines can be added to an option by using the '--add' option.
+If you want to update or unset an option which can occur on multiple
+lines, a POSIX regexp `value_regex` needs to be given. Only the
+existing values that match the regexp are updated or unset. If
+you want to handle the lines that do *not* match the regex, just
+prepend a single exclamation mark in front (see also <<EXAMPLES>>).
+
+The type specifier can be either '--int' or '--bool', which will make
+'git-config' ensure that the variable(s) are of the given type and
+convert the value to the canonical form (simple decimal number for int,
+a "true" or "false" string for bool). If no type specifier is passed,
+no checks or transformations are performed on the value.
+
+The file-option can be one of '--system', '--global' or '--file'
+which specify where the values will be read from or written to.
+The default is to assume the config file of the current repository,
+.git/config unless defined otherwise with GIT_DIR and GIT_CONFIG
+(see <<FILES>>).
+
+This command will fail if:
+
+. The config file is invalid,
+. Can not write to the config file,
+. no section was provided,
+. the section or key is invalid,
+. you try to unset an option which does not exist,
+. you try to unset/set an option for which multiple lines match, or
+. you use '--global' option without $HOME being properly set.
+
+
+OPTIONS
+-------
+
+--replace-all::
+ Default behavior is to replace at most one line. This replaces
+ all lines matching the key (and optionally the value_regex).
+
+--add::
+ Adds a new line to the option without altering any existing
+ values. This is the same as providing '^$' as the value_regex.
+
+--get::
+ Get the value for a given key (optionally filtered by a regex
+ matching the value). Returns error code 1 if the key was not
+ found and error code 2 if multiple key values were found.
+
+--get-all::
+ Like get, but does not fail if the number of values for the key
+ is not exactly one.
+
+--get-regexp::
+ Like --get-all, but interprets the name as a regular expression.
+ Also outputs the key names.
+
+--global::
+ For writing options: write to global ~/.gitconfig file rather than
+ the repository .git/config.
++
+For reading options: read only from global ~/.gitconfig rather than
+from all available files.
++
+See also <<FILES>>.
+
+--system::
+ For writing options: write to system-wide $(prefix)/etc/gitconfig
+ rather than the repository .git/config.
++
+For reading options: read only from system-wide $(prefix)/etc/gitconfig
+rather than from all available files.
++
+See also <<FILES>>.
+
+-f config-file::
+--file config-file::
+ Use the given config file instead of the one specified by GIT_CONFIG.
+
+--remove-section::
+ Remove the given section from the configuration file.
+
+--rename-section::
+ Rename the given section to a new name.
+
+--unset::
+ Remove the line matching the key from config file.
+
+--unset-all::
+ Remove all lines matching the key from config file.
+
+-l::
+--list::
+ List all variables set in config file.
+
+--bool::
+ 'git-config' will ensure that the output is "true" or "false"
+
+--int::
+ 'git-config' will ensure that the output is a simple
+ decimal number. An optional value suffix of 'k', 'm', or 'g'
+ in the config file will cause the value to be multiplied
+ by 1024, 1048576, or 1073741824 prior to output.
+
+-z::
+--null::
+ For all options that output values and/or keys, always
+ end values with the null character (instead of a
+ newline). Use newline instead as a delimiter between
+ key and value. This allows for secure parsing of the
+ output without getting confused e.g. by values that
+ contain line breaks.
+
+--get-colorbool name [stdout-is-tty]::
+
+ Find the color setting for `name` (e.g. `color.diff`) and output
+ "true" or "false". `stdout-is-tty` should be either "true" or
+ "false", and is taken into account when configuration says
+ "auto". If `stdout-is-tty` is missing, then checks the standard
+ output of the command itself, and exits with status 0 if color
+ is to be used, or exits with status 1 otherwise.
+ When the color setting for `name` is undefined, the command uses
+ `color.ui` as fallback.
+
+--get-color name default::
+
+ Find the color configured for `name` (e.g. `color.diff.new`) and
+ output it as the ANSI color escape sequence to the standard
+ output. The optional `default` parameter is used instead, if
+ there is no color configured for `name`.
+
+[[FILES]]
+FILES
+-----
+
+If not set explicitly with '--file', there are three files where
+'git-config' will search for configuration options:
+
+$GIT_DIR/config::
+ Repository specific configuration file. (The filename is
+ of course relative to the repository root, not the working
+ directory.)
+
+~/.gitconfig::
+ User-specific configuration file. Also called "global"
+ configuration file.
+
+$(prefix)/etc/gitconfig::
+ System-wide configuration file.
+
+If no further options are given, all reading options will read all of these
+files that are available. If the global or the system-wide configuration
+file are not available they will be ignored. If the repository configuration
+file is not available or readable, 'git-config' will exit with a non-zero
+error code. However, in neither case will an error message be issued.
+
+All writing options will per default write to the repository specific
+configuration file. Note that this also affects options like '--replace-all'
+and '--unset'. *'git-config' will only ever change one file at a time*.
+
+You can override these rules either by command line options or by environment
+variables. The '--global' and the '--system' options will limit the file used
+to the global or system-wide file respectively. The GIT_CONFIG environment
+variable has a similar effect, but you can specify any filename you want.
+
+
+ENVIRONMENT
+-----------
+
+GIT_CONFIG::
+ Take the configuration from the given file instead of .git/config.
+ Using the "--global" option forces this to ~/.gitconfig. Using the
+ "--system" option forces this to $(prefix)/etc/gitconfig.
+
+See also <<FILES>>.
+
+
+[[EXAMPLES]]
+EXAMPLES
+--------
+
+Given a .git/config like this:
+
+ #
+ # This is the config file, and
+ # a '#' or ';' character indicates
+ # a comment
+ #
+
+ ; core variables
+ [core]
+ ; Don't trust file modes
+ filemode = false
+
+ ; Our diff algorithm
+ [diff]
+ external = /usr/local/bin/diff-wrapper
+ renames = true
+
+ ; Proxy settings
+ [core]
+ gitproxy="proxy-command" for kernel.org
+ gitproxy=default-proxy ; for all the rest
+
+you can set the filemode to true with
+
+------------
+% git config core.filemode true
+------------
+
+The hypothetical proxy command entries actually have a postfix to discern
+what URL they apply to. Here is how to change the entry for kernel.org
+to "ssh".
+
+------------
+% git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'
+------------
+
+This makes sure that only the key/value pair for kernel.org is replaced.
+
+To delete the entry for renames, do
+
+------------
+% git config --unset diff.renames
+------------
+
+If you want to delete an entry for a multivar (like core.gitproxy above),
+you have to provide a regex matching the value of exactly one line.
+
+To query the value for a given key, do
+
+------------
+% git config --get core.filemode
+------------
+
+or
+
+------------
+% git config core.filemode
+------------
+
+or, to query a multivar:
+
+------------
+% git config --get core.gitproxy "for kernel.org$"
+------------
+
+If you want to know all the values for a multivar, do:
+
+------------
+% git config --get-all core.gitproxy
+------------
+
+If you like to live dangerous, you can replace *all* core.gitproxy by a
+new one with
+
+------------
+% git config --replace-all core.gitproxy ssh
+------------
+
+However, if you really only want to replace the line for the default proxy,
+i.e. the one without a "for ..." postfix, do something like this:
+
+------------
+% git config core.gitproxy ssh '! for '
+------------
+
+To actually match only values with an exclamation mark, you have to
+
+------------
+% git config section.key value '[!]'
+------------
+
+To add a new proxy, without altering any of the existing ones, use
+
+------------
+% git config core.gitproxy '"proxy-command" for example.com'
+------------
+
+An example to use customized color from the configuration in your
+script:
+
+------------
+#!/bin/sh
+WS=$(git config --get-color color.diff.whitespace "blue reverse")
+RESET=$(git config --get-color "" "reset")
+echo "${WS}your whitespace color or blue reverse${RESET}"
+------------
