Interestingly, the command doesn't delete anything; it creates a new commit that introduces changes which revert the effects of the specified commit. Step 4 - Checking Git status and viewing the history: Now let's make sure that the previous three procedures are done correctly by running a git status command followed by a git log to see the history of changes in the local repository.

Is it already in the remote repository? This is a safe way to undo changes, as it has no chance of re-writing the commit history. If you have the master branch checked out locally, you can also do it in two simpler steps: First reset the branch to the parent of the current commit, then force-push it to the remote. We also assume that you have the required Git knowledge of repositories and how to clone a remote one to your local system.
