Here\'s what I did on my supposed-to-be-stable branch...

% git rebase master
First, rewinding head to repla         


        

Answer 1

Scenario 1: If you want to undo the last commit say 8123b7e04b3, below is the command(this worked for me):

git push origin +8123b7e04b3^:

Output looks like below:

Total 0 (delta 0), reused 0 (delta 0)
To https://testlocation/code.git
 + 8123b7e...92bc500 8123b7e04b3^ -> master (forced update)

Additional info: Scenario 2: In some situation, you may want to revert back what you just undo'ed (basically undo the undo) through the previous command, then use the below command:

git reset --hard 8123b7e04b3

Output:

HEAD is now at cc6206c Comment_that_was_entered_for_commit
