1. Git Revert
When to Use:
Use git revert to undo a specific commit while preserving your commit history. It’s ideal for public repositories where rewriting history can cause issues.
How It Works:
git revert creates a new commit that undoes the changes introduced by the targeted commit.
Example:
git revert <commit-hash>
Git will prompt you to edit a commit message. Save it, and a new commit reversing the changes will be added.
2. Git Reset
When to Use:
Use git reset to undo changes by moving the HEAD pointer. This command is more destructive than revert as it alters commit history.
Modes of git reset:
-
--soft: Keeps changes in the staging area. -
--mixed(default): Keeps changes in your working directory. -
--hard: Discards changes completely.
Example:
# Reset to a specific commit and keep changes in working directory git reset --mixed <commit-hash> # Reset and discard changes git reset --hard <commit-hash>
⚠️ Be cautious with
--hardas it permanently deletes changes.
3. Git Checkout
When to Use:
Use git checkout to switch branches or restore files to a specific state.
Switching Branches:
git checkout <branch-name>
Restoring Files:
Restore a specific file to the state of the last commit:
git checkout HEAD -- <file-name>
When to Use What?
- Revert: Undo a specific commit in a shared repository.
- Reset: Rewrite commit history in local branches.
- Checkout: Switch branches or restore files without modifying commits.
Best Practices
- Understand the Impact:
- Use
revertfor safe, non-destructive changes. - Use
resetonly when working locally or with private branches.
- Use
- Always Backup:
- Before using
reset --hard, stash your changes or back up the branch.
- Before using
- Collaborate:
- For shared repositories, communicate with your team before altering history.
Conclusion
