The git reset command can be used to undo a merge by specifying the commit before the merge we want to revert back. In the following example, we undo merge by specifying the command like below.

Alternatively, we can use the HEAD~1 pointer in order to specify the previous commit before the merge.

$ git reset --hard HEAD~1

If the merge is pushed into the central repository the steps described above do not work. So after pushing the merge into the repository how can we revert the merge back.

$ git revert -m 1 23abed625
