git - How to delete commit that is pushed to the remote repository?

Question

A local branch:-

'feature/100'

And Remote branches:-

'master'

'Version2'

Accidently,

1. I have merged my feature branch 'feature/100' to the master
2. Also pushed it to the remote repository.

But in real 'feature/100' should have been merged into remote branch 'Version2'

How I fixed it (partially):-

i have merged the feature branch 'feature/100' to the remote branch 'Version2' and pushed it to the server.

git checkout Version2
git merge --squash feature/100
git add .
git commit -m 'New message'

But I want to delete the last push I have merged and commit to the master branch. How?

Side Note I am only one working on this project.. So even if pushed commit is deleted it won't harm anyone else

Answer 1

You can either:

Revert your change

git revert HEAD

This will create a new commit that reverts the changes that you just pushed up to master. This is the safest option because other people may have already pulled down the change that you have pushed up.

Change your commit history and force push the change

You can remove the commit that you just pushed up with:

git reset --hard HEAD~1

git push origin master --force

You don't want to do this unless you're absolutely sure that no one has pulled down your changes from master.
