There will be a time when you need to delete a branch from your local and remote. Here is how I do it.
techcater@gbcweb02:$ git branch -d JulietV1.0 Deleted branch JulietV1.0 (was b6d2429). techcater@gbcweb02:$ git push origin --delete JulietV1.0 Password for 'https://firstname.lastname@example.org': To https://email@example.com/dalenguyen/juliet-research.git - [deleted] JulietV1.0
You're welcome ;)
