How to delete the last n commits on Github and locally?

To remove the last two commits locally I'd suggest using:

git reset --hard HEAD^^

Rebase is a completely different operation that won't help you here.

If you want to remove the 2 (two) last commits, there is an easy command to do that:

git reset --hard HEAD~2

You can change the 2 for any number of last commits you want to remove.

And to push this change to remote, you need to do a git push with the force (-f) parameter:

git push -f

However, I don't recommend to do any git command with -f or --hard options involved if there are new commits on remote (Github) after this commits that you want to remove. In that case, always use git revert.

The following works for me

git reset HEAD~n

It removes the last n commits from local repo, as HEAD^ removes only one. If you need to remove these changes from remote, you might need to force push as you will be behind remote.

git push -f origin <branch>

To remove the last n commits:

git reset HEAD~n

If you need to remove these changes from remote, you might need to force push as you will be behind remote.

git push -f origin <Branch Name>
