How to undo the last commit on GitHub?

To undo the last commit on GitHub, you can use the following steps based on your situation:

If You Have Not Pushed the Commit:

1. Remove the Last Commit but Keep Changes:
   bash

   Copy code

   git reset --soft HEAD~1


   This will undo the last commit and leave your changes staged for a new commit.

2. Remove the Last Commit and Discard Changes:
   bash

   Copy code

   git reset --hard HEAD~1


   This completely removes the last commit and any changes made in it.

If You Have Already Pushed the Commit:

1. Undo Locally and Force Push:
   If the commit has been pushed, use git reset followed by a force push:
   bash

   Copy code

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


   Note: Force-pushing can overwrite others’ work if they have also made changes. Use it cautiously.

2. Revert the Commit (Safe for Shared Repositories):
   If others might have pulled the changes, create a new commit to undo the changes:
   bash

   Copy code

   git revert HEAD


   This creates a new commit that reverses the last commit’s changes.

Choose the method based on whether you’ve pushed the commit and whether others are collaborating on the branch.
