Despite all the fixes you try, faulty commits occasionally make it into the central repository. Still, this is no reason to despair since git offers an easy way to revert single or multiple commits:
Revert the commit with the specified id
git revert c761f5c
Revert the second to last commit.
git revert HEAD^
Revert a whole range of commits.
git revert develop~4..develop~2
In case you don’t want to create additional revert commits but only apply the necessary changes to your working tree, you can use the --no-commit/-n option.
# undo the last commit, but don't create a revert commit
git revert -n HEAD
The manual page at man 1 git-revert list further options and provides some additional examples.
