git config

Manage custom configuration options for Git repositories. These configurations can be local (for the current repository) or global (for the current user). More information: https://git-scm.com/docs/git-config.

• Globally set your name or email (this information is required to commit to a repository and will be included in all commits):

git config --global {{user.name|user.email}} "{{Your Name|email@example.com}}"

• List local or global configuration entries:

git config --list --{{local|global}}

• List only system configuration entries (stored in /etc/gitconfig), and show their file location:

git config --list --system --show-origin

• Get the value of a given configuration entry:

git config alias.unstage

• Set the global value of a given configuration entry:

git config --global alias.unstage "reset HEAD --"

• Revert a global configuration entry to its default value:

git config --global --unset alias.unstage

• Edit the local Git configuration (.git/config) in the default editor:

git config --edit

• Edit the global Git configuration (~/.gitconfig by default or $XDG_CONFIG_HOME/git/config if such a file exists) in the default editor:

git config --global --edit
