Undo Last Commit

If you’ve committed changes in Git but haven’t pushed them yet, you have a few ways to "uncommit" depending on whether you want to keep the changes or discard them.

1. Undo the last commit but keep the changes (soft reset)

git reset --soft HEAD~1

• This will remove the last commit but keep your changes staged (ready to be committed again).

2. Undo the last commit and unstage the changes (mixed reset)

git reset --mixed HEAD~1

• This removes the last commit and unstages the changes, but your modified files remain in your working directory.

3. Undo the last commit and discard all changes (hard reset)

git reset --hard HEAD~1

• ⚠ Warning: This will delete the commit and all changes in the working directory. Only use this if you're sure you don't need the changes.

4. Undo multiple commits

If you want to undo the last 2 commits, replace HEAD~1 with HEAD~2:

git reset --soft HEAD~2

(Replace 2 with however many commits you want to undo.)

5. If you already pushed the commit (Force Push)

If you've already pushed the commit and want to undo it:

git reset --hard HEAD~1
git push --force

 git commit --date="" -m ""

Ignore Files

touch .gitignore
