Deleting the commit in Git must be approached in one of two ways, depending on if you have or have not pushed your changes. Please note before attempting this, running these commands will DELETE your working directory changes. Any changes to tracked files in the working tree since <commit> are discarded. Be sure to separately save any changes you'd like to have.
If your changes have not been pushed yet simply enter the command
git reset --hard HEAD~1
This will discard all working tree changes and move HEAD to the commit before HEAD.
If you'd like to delete the commits up until a specific commit, running <git log> into the command line to find the specific commit id and then running
git reset --hard <sha1-commit-id>
will discard all working tree changes and move HEAD to the commit chosen.
Alternatively, if you have already pushed your changes you will need to run the following code
git push origin HEAD --force
Please note if others have pulled this branch you would be better off starting a new branch. If you don't do this when someone else pulled, it will just merge it into their work, and you will get it pushed back up again.
If you need to find a commit that you "deleted", it is typically present in <git reflog> unless you have garbage collected your repository.
