How can I undo a git rebase?

I accidentally rebased my branch and now I want to undo it. How can I do that?

You can undo a git rebase by using the command git reflog to find the commit before the rebase, then use git reset --hard <commit>.

What if I already pushed the rebased branch to the remote repository?

If you've pushed the rebased branch, you'll need to force push the reset branch using git push origin <branch-name> --force.

Are there any risks with force pushing?

Yes, force pushing can overwrite changes on the remote branch, which may affect other collaborators. It's best to communicate with your team before doing it.

Is there a safer way to revert changes without using force push?

You can create a new commit that reverts the changes made by the rebase using git revert <commit> for each commit you want to undo.
