Git hooks

Hooks are programs you can place in a hooks directory to trigger actions at certain points in git’s execution. $GIT_DIR/hooks/* (or git config core.hooksPath/*)

Before Git invokes a hook, it changes its working directory to either $GIT_DIR in a bare repository or the root of the working tree in a non-bare repository. An exception are hooks triggered during a push (pre-receive, update, post-receive, post-update, push-to-checkout) which are always executed in $GIT_DIR.

Common hooks

pre-commit: invoked before git commit

pre-push: invoked before push (can stop push)

Git rebase

git rebase: reapply all commits from current branch to tip of another branch.

Note: - These commits are new commits, not identical to previous commits. - Golden rule: Never rebase a branch shared by others
