Imagine that you cloned an open source project to contribute something. You implemented a bugfix through a series of atomic commits on a private branch. Just when you’re about to create a Pull Request to submit your changes, you discover in the contributor’s guide that you’re supposed to prefix each commit with the bug tracking number.
Rewriting the commit message of the last commit is easy:
git commit --amend
