How can I remove a commit on GitHub?

Question

I "accidentally" pushed a commit to GitHub.

Is it possible to remove this commit?

I want to revert my GitHub repository as it was before this commit.

Answer 1

Let's say you've performed two committed and pushed them by mistake.Now you found out that commit XXXXX was before those wrongful commits. Then force push the last perfect commit as the new master. 

Step 1: Find out the commit you want to revert using the following command:

git log

Say, XXXX is the commit before the wrongly pushed commit. 

Step 2:  Force push the commit as the master

git push origin +XXXXX:master

Here, + is used for force push
