Revert

Sometimes we end up making changes that need to be rolled back.

Git revert is a shorthand for undoing changes. It creates a new commit that undoes the changes from the previous commit.

Command

git revert <commit-ish>

Exercise: Revert a commit

• Navigate to the learn-git repository.
• Revert the commit with log message E.
• Check the logs to see the new revert commit.

Hint: Use git log to find the commit hash.

Solution: Revert a commit

Navigate to the learn-git repository.

git revert 1fef21501625d1cb1ab99318ad0fa8487d6ef5cb

Note: We may get a revert conflict. Yes, we can get conflicts on reverts too. If so, resolve the conflict and commit the changes.

We can see the new commit in the logs.

git log --oneline --graph

Output

* d1a64a9 (HEAD -> main) Revert "E"
