Question

Is there a way to trigger a hook after a new branch has been checked out in Git?

Answer 1

If one of these hooks won’t do it I’d be amazed:

Maybe this one:

post-checkout

This hook is invoked when a git-checkout is run after having updated the worktree. The hook is given three parameters: the ref of the previous HEAD, the ref of the new HEAD (which may or may not have changed), and a flag indicating whether the checkout was a branch checkout (changing branches, flag=1) or a file checkout (retrieving a file from the index, flag=0). This hook cannot affect the outcome of git-checkout.
