Due to some bad cherry-picking, my local Git repository is currently five commits ahead of the origin, and not in a good state. I want to get rid of all these commits and start over again.
Obviously, deleting my working directory and re-cloning would do it, but downloading everything from GitHub again seems like overkill and not a good use of my time.
Maybe git revert is what I need, but I don't want to end up 10 commits ahead of the origin (or even six), even if it does get the code itself back to the right state. I just want to pretend the last half-hour never happened.
Is there a simple command that will do this? It seems like an obvious use case, but I'm not finding any examples of it.
Note that this question is specifically about commits, not about:
staged, but uncommitted changes
