git revert can be used to revert the changes you did in your git repository. One of the most useful case would be if you have already published your commits and of course, you won’t want to do a history rewrite. Then git revert lets you make a new commit cancelling out the effect of particular commit you specify.
and note down the commit id of the latest commit you want to revert. Let us assume, it’s “b338b072ex1gd89a1a4eba8ge0d56jko“.
Then do git log again and see a new commit reverting the changes of last commit. Similarly, it can be done for multiple commits to, or a range of commits.
