Git Configuration
Internal
Overview
Git maintains configuration in a hierarchy of files.
System-wide configuration is maintained in /etc/gitconfig. This configuration applies to all users of the system and it is read and written by git config --system [...]
User-specific configuration is maintained in in ~/.gitconfig or ~/.config/git/config. This configuration applies to a specific user, and it is read and written by git config --global [...]
Repository specific configuration is maintained in .git/config and it read and written with git config --local [...]
If no option is specified, --local is the default.
If the same configuration element is specified in multiple locations, the most specific value becomes the effective value: a repository-level value takes precedence over a user-level values, which takes precedence over the corresponding system-level value. To obtain the effective value of a configuration element, execute git config --get.
The configuration files are plain-text, so values can be set manually by editing the file and using the correct syntax. It’s generally easier to run the git config command, though.
