[Git 常見問題] Rename a local and remote branch in git

 Source From Here

Question
If you have named a branch incorrectly AND pushed this to the remote repository follow these steps before any other developers get a chance to jump on you and give you shit for not correctly following naming conventions. How are you going to rename your branch?

HowTo

1. Rename your local branch.
If you are on the branch you want to rename:

$ git branch -m new-name

If you are on a different branch:

$ git branch -m old-name new-name

2. Delete the old-name remote branch and push the new-name local branch.

$ git push origin :old-name new-name

3. Reset the upstream branch for the new-name local branch.
Switch to the branch and then:

$ git push origin -u new-name
