Local hooks

Local hooks affect only the local repositories in which they reside. Each developer can alter their own local hooks, so they can’t be used reliably as a way to enforce a commit policy. They are designed to make it easier for developers to adhere to certain guidelines and avoid potential problems down the road.

There are six types of local hooks: pre-commit, prepare-commit-msg, commit-msg, post-commit, post-checkout, and pre-rebase.

The first four hooks relate to commits and allow you to have some control over each part in a commit’s life cycle. The final two let you perform some extra actions or safety checks for the git checkout and git rebase commands.

All of the “pre-” hooks let you alter the action that’s about to take place, while the “post-” hooks are used primarily for notifications.
