To create a new commit that  undoes  the changes of a past commit  use    git revert  lt commit-hash gt   It s also possible to actually remove a commit from an arbitrary point in the past by rebasing and then resetting  but you really don t want to do that if you have already pushed your commits to another repository  or someone else has pulled from you   If your previous commit is a merge commit you can run this command   git revert -m 1  lt commit-hash gt   See schacon github com git howto revert-a-faulty-merge txt for proper ways to re-merge an un-merged branch

To revert a merge commit  you need to use  git revert -m  lt parent number gt   So for example  to revert the recent most merge commit using the parent with number 1 you would use   git revert -m 1 HEAD   To revert a merge commit before the last commit  you would do   git revert -m 1 HEAD    Use git show  lt merge commit SHA1 gt  to see the parents  the numbering is the order they appear e g  Merge  e4c54b3 4725ad2  git merge documentation  http   schacon github com git git-merge html  git merge discussion  confusing but very detailed    http   schacon github com git howto revert-a-faulty-merge txt
