Question

I committed something and realize my comment had a spelling error, so I typed git commit -m "xxx" again, with corrected comment.

As a result, I can’t push anything as git push says

Everything up-to-date

# On branch master
# Your branch is ahead of 'origin/master' by 1 commit. 
#
nothing to commit (working directory clean)

What can I do now?

Answer 1

git rebase -i origin/master will give you the opportunity to correct the commits you have beyond your upstream repository. Then you can git push the result.
