git reset --hard is the tool you call when you want to throw away local changes with extreme prejudice. It works exactly as advertised and it does not ask how you are feeling about that decision. That means it is useful and terrifying in equal measure. This guide walks through a sane workflow for git reset hard while keeping commit recovery tools handy.
Before you press the big reset button run these commands to see what the repo looks like and to avoid dramatic surprises.
git status
git log --oneline
git status shows staged and unstaged files and git log --oneline shows the recent commits and where HEAD points. If you skip this you will still learn something later when you explain to your team why a commit vanished.
Pick the commit you want HEAD to point at. You can use a full SHA or a relative ref like HEAD~1. If you prefer a guided tour use git reflog to see every movement of HEAD and pick the entry you meant to keep.
git log --oneline
git reflog
If there is anything you might regret losing stash it or make a quick temporary branch. Memory is famously unreliable under deadline pressure.
git stash push -m "save before reset"
# or
git branch temp-save
git add .
git commit -m "temp save"
Now for the actual action. This moves HEAD, updates the index and replaces files in your working tree. It is blunt and efficient so be sure you really want to remove those changes.
git reset --hard
If you are working with a shared branch and need to update the remote you will likely use a force push. Be careful and coordinate with your team when using git push --force.
Double check the result so you can relax or panic in an organized way.
git status
git log --oneline
If you discover you reset the wrong commit do not panic. git reflog tracks recent HEAD moves. Find the reflog entry with the lost commit and reset back to it.
git reflog
git reset --hard
Create a branch before dramatic resets and when in doubt stash first. That keeps recoveries trivial and your regret levels manageable when deadlines meet aggressive editing.
