How to revert a merge commit that's already pushed to remote branch?

Question

git revert alone won\'t work. -m must be specified, and I\'m pretty confused about it.

Anyone experienced this before?<

Answer 1

Sometimes the most effective way to rollback is to step back and replace.

git log

Use the 2nd commit hash (full hash, the one you want to revert back to, before the mistake listed) and then rebranch from there.

git checkout -b newbranch

Then delete the old branch, copy the newbranch over in its place and restart from there.

git branch -D oldbranch
git checkout -b oldbranch newbranch

If its been broadcast, then delete the old branch from all repositories, push the redone branch to the most central, and pull it back down to all.
