git revert — Safely Undoing a Commit

The Safe Way to Undo (Especially on Shared Branches)

git revert creates a new commit that undoes a previous commit — it doesn't rewrite history. This makes it safe to use on shared/public branches where rewriting history would break others' repos.

git revert HEAD            # undo last commit (opens editor for message)
git revert HEAD --no-edit  # undo last commit, keep generated message
git revert abc1234         # undo a specific commit by hash
git revert HEAD~2..HEAD    # undo last 2 commits (creates 2 revert commits)

reset vs revert

	git reset	git revert
Rewrites history	Yes	No
Safe for shared branches	❌ Never	✅ Always
Creates new commit	No	Yes

Your Task

A bug was introduced in the last commit. Use git revert HEAD --no-edit to create a revert commit. The file should go back to its previous content.
