Amending a commit

One of the better things about Git is that you can undo almost anything; you only need to know how to. This is because no matter how carefully you craft your commits, sooner or later, you’ll forget to add a change or mistype the commit message. That’s when the --amend flag of the git commit command comes in handy; it allows you to change the very last commit really easily. Note that with git commit -- amend, you can also amend the merge commits (for example, to fix a merging error). Figure 2.4 shows how this amend operation changes the graph of revisions which represents the history of the project.
