use can use git reset for that
git reset --hard HEAD~3
git push --force origin master
where HEAD~3 means go back 3 commits
You can also use the commit number instead of 3 commits, so that you are sure where you are going back in time, like
git reset --hard 8315cd7962c902d39160fcf2fd018f249e7cf744
EDIT:
When rewriting history, prefer using
git push origin +master
To be safe if you are ever pushing more than one branch. You can read more at Git Force push syntax, “-f” versus “+branch”
(kudor to Josef Kufner comment pointing it out)
EDIT 2:
I just noticed that your log is printing colors as codes, So
git reset -- hard 33m8315cd7962c902d39160fcf2fd018f249e7cf744
will not work, [[33m and [[m are color codes! So your commit number is actually 8315cd7962c902d39160fcf2fd018f249e7cf744
If you do
git reset --hard 8315cd7962c902d39160fcf2fd018f249e7cf744
it should work as well.
(Fixed the commit code on previous examples as well)
