github rollback- How can I rollback a github repository to a specific commit?

Question

My Github has 100 commits in it right now. I need to rollback the repository to commit 80 and remove all the subsequent ones.

Why? This repo is supposed to be for merging from miscellaneous users. A bunch of merges went in as commits from me, due to excessive editing. That was due to a mislabeling of my remote branches, where 3 developers were labelled as each other. I need to reset to that point and then pull forward.

However, git wants me to do a lot of conflict management. Is there a simpler way?

Answer 1

You can use either of the two below mentioned commands:

git reset --hard <old-commit-id> 

git push -f <remote-name> <branch-name>

Note that using this is dangerous in a collaborative environment: as you're rewriting history
