What Does Git Revert Do?
The git revert command undoes a previous commit by creating a new commit that reverses the changes.
This keeps your commit history intact and is the safest way to undo changes in a shared repository.
Summary of Git Revert Commands and Options
- git revert HEAD - Revert the latest commit
- git revert <commit> - Revert a specific commit
- git revert HEAD~2 - Revert a commit further back in history
- git revert --no-edit - Skip commit message editor
- git log --oneline - Show commit history
How to Find the Commit to Revert
First, you need to find the commit you want to undo.
Use git log --oneline to see a summary of your commit history:

git log --oneline
