DESCRIPTION
-----------
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 EXAMPLES).
+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). Type specifiers currently only
-take effect for reading operations. If no type specifier is passed,
+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 .git/config file is invalid,
-. Can not write to .git/config,
+. 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.
+. you use '--global' option without $HOME being properly set.
OPTIONS
--get-regexp::
Like --get-all, but interprets the name as a regular expression.
+ Also outputs the key names.
--global::
- Use global ~/.gitconfig file rather than the repository .git/config.
+ 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::
- Use system-wide $(prefix)/etc/gitconfig rather than the repository
- .git/config.
+ For writing options: write to system-wide $(prefix)/etc/gitconfig
+ rather than the repository .git/config.
++
+For reading options: read only from system-wide $(prefix)/etc/gitconfig
+rather than from all available files.
++
+See also <<FILES>>.
+
+-f config-file, --file config-file::
+ Use the given config file instead of the one specified by GIT_CONFIG.
--remove-section::
Remove the given section from the configuration file.
in the config file will cause the value to be multiplied
by 1024, 1048576, or 1073741824 prior to output.
+-z, --null::
+ For all options that output values and/or keys, always
+ end values with with the null character (instead of a
+ newline). Use newline instead as a delimiter between
+ key and value. This allows for secure parsing of the
+ output without getting confused e.g. by values that
+ contain line breaks.
+
+
+[[FILES]]
+FILES
+-----
+
+If not set explicitly with '--file', there are three files where
+git-config will search for configuration options:
+
+$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.
+
+The GIT_CONFIG_LOCAL environment variable on the other hand only changes
+the name used instead of the repository configuration file. The global and
+the system-wide configuration files will still be read. (For writing options
+this will obviously result in the same behavior as using GIT_CONFIG.)
+
ENVIRONMENT
-----------
GIT_CONFIG::
Take the configuration from the given file instead of .git/config.
- Using the "--global" option forces this to ~/.gitconfig.
+ Using the "--global" option forces this to ~/.gitconfig. Using the
+ "--system" option forces this to $(prefix)/etc/gitconfig.
GIT_CONFIG_LOCAL::
- Currently the same as $GIT_CONFIG; when Git will support global
- configuration files, this will cause it to take the configuration
- from the global configuration file in addition to the given file.
+ Take the configuration from the given file instead if .git/config.
+ Still read the global and the system-wide configuration files, though.
+See also <<FILES>>.
