By default on Windows Git places global .gitconfig in c:\\documents and settings\\user\\
How can I change that position so .gitconfig is stored in
As someone who has been interested in this for a VERY LONG TIME. See from the manual:
$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.
Which was only recently added. This dump is from 2.15.0.
Works for me.
