Scenario

You have created a commit locally that contains incorrect changes and you want to completely erase it from history.

Task

Navigate to /home/interview/repo. Remove the last commit entirely and discard all associated file changes.

Example

# Before (Bad commit exists)
$ git log --oneline -2
c3d4e5f (HEAD -> main) Bad commit - wrong changes
b2c3d4e Add feature implementation

# After (Clean history)
$ git log --oneline -2
b2c3d4e (HEAD -> main) Add feature implementation

Step 1: Verify current position
Navigate to the repository and check the commit log to confirm the commit you are about to delete.

cd /home/interview/repo
git log --oneline -2

Step 2: Reset the branch
Move the branch pointer back one step (HEAD~1) and force the working directory to match (--hard), effectively deleting the changes.

git reset --hard HEAD~1
