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. 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-nam e 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
