How do I delete a Git branch both locally and in Github?
First of all, I read how to remove a branch, but for some reason is not working on my project: https://github.com/ralcr/sdk.ralcr
When you first enter here you see some files 10 months old in a gh-pages branch. I have no idea how this branch was created and why it's displayed first, but I want to remove it and this is not working
Balutas-MacBook-Pro:sdk.ralcr Cristi$ git push origin --delete gh-pages
fatal: 'origin' does not appear to be a git repository
fatal: The remote end hung up unexpectedly
I want only the master branch.
