It's possible that we will do something wrong, well, we're all just human, we always do something wrong (or may be right).
Git branch are something that I always define it in wrong pattern 🤣.
Here how to fix it.
- you need to change branch name in local first
$ git branch -m old-branch-name new-branch-name
What it does? it dose change local branch name from old-branch-name to new-branch-name. You can check with git log you will found that the old-branch-name are gone!
- change branch name in remote
This part are required when the old-branch-name are in remote. What you need to do is just push the new-branch-name into remote then remove the old-branch-name in remote that's it.
$ git push origin -u new-branch-name
$ git push origin -d old-branch-name
Now, the old-branch-name are gone both local and remote.
