# Rollback Commits
|
|
|
|
## Undo Commits
|
|
|
|
- Undo last commit putting everything back into the staging area:
|
|
|
|
```shell
|
|
git reset --soft HEAD^
|
|
```
|
|
|
|
- Add files and change message with:
|
|
|
|
```shell
|
|
git commit --amend -m "New Message"
|
|
```
|
|
|
|
- Undo last and remove changes:
|
|
|
|
```shell
|
|
git reset --hard HEAD^
|
|
```
|
|
|
|
- Same as last one but for two commits back:
|
|
|
|
```shell
|
|
git reset --hard HEAD^^
|
|
```
|
|
|

## Note
|
|
|
|
- `git revert` vs `git reset`
|
|
- Reset removes the commit while revert removes the changes but leaves the commit
|
|
- Revert is safer considering we can revert a revert
|
|
|
|
```shell
|
|
# Changed file
|
|
git commit -am "bug introduced"
|
|
git revert HEAD
|
|
# New commit created reverting changes
|
|
# Now we want to re apply the reverted commit
|
|
git log # take hash from the revert commit
|
|
git revert <rev commit hash>
|
|
# reverted commit is back (new commit created again)
|
|
```
