Git: Revert and Reset

Git revert and reset is used to undo changes.

Git revert

• Create new commit in order to reflect the changes.
• git revert HEAD means revert to commit before HEAD.
• Used when the change is already pushed to repository.
• Reverting merged commit needs an additional flag -m n where n is a number >0.

Git reset

• Move the HEAD to a specific commit in order to reflect the changes.
• git reset HEAD means point HEAD to a commit at HEAD, which will do nothing.
• Used before the change is pushed to repository.
