Question

I made a series of commits after a good commit on the master branch, which in hindsight I should have made in another branch. Can I move those commits, beginning with a specific commit, to another branch, and keep the good commit as the last commit on master?

Answer 1

Sure:

$ git branch new-branch-name                       # Create a new branch from the current commit
$ git reset --hard <last good commit on master>    # Reset master to the good commit
