提交了正确的分支，但是又推错了分支，如何撤消推？

Question

I made some changes on branch1 , committed them, checked out branch2 , made changes and committed them.

I pushed branch1 to GitHub by mistake.

I then pushed branch2 .

Because I only meant to push branch2 , I want to undo the branch1 push.

Basically I did the following:

git checkout -b branch1
//make some changes on branch1
git commit -am "changes on branch1"
git checkout -b branch2
//make some different changes on branch2
git commit -am "changes on branch2"
git push origin branch1 //whoops!
git push origin branch2 //this is what I meant to do

I want to undo the branch1 push but not the branch2 push; how do I do this?

Answer 1

Assuming you only pushed a single change

git push origin +branch1^:branch1

will roll back the branch1 head on origin to the previous commit.
