'--file <filename>' can be used to tell the command to write to
that location (you can say '--local' but that is the default).

On success, the command returns the exit code 0.

For writing options: write to global ~/.gitconfig file rather than
- the repository .git/config.
+ the repository .git/config, write to $XDG_CONFIG_HOME/git/config file

FILES

-If not set explicitly with '--file', there are three files where
+If not set explicitly with '--file', there are four files where
'git config' will search for configuration options:
$GIT_DIR/config::
User-specific configuration file. Also called "global"
configuration file.
+$XDG_CONFIG_HOME/git/config::
+ Second user-specific configuration file. If $XDG_CONFIG_HOME is not set
+ or empty, $HOME/.config/git/config will be used. Any single-valued
+ variable set in this file will be overwritten by whatever is in
+ ~/.gitconfig. It is a good idea not to create this file if
+ you sometimes use older versions of Git, as support for this
+ file was added fairly recently.
+
$(prefix)/etc/gitconfig::
System-wide configuration file.
Using the "--global" option forces this to ~/.gitconfig. Using the
"--system" option forces this to $(prefix)/etc/gitconfig.
+GIT_CONFIG_NOSYSTEM::
+ Whether to skip reading settings from the system-wide
+ $(prefix)/etc/gitconfig file. See linkgit:git[1] for details.
