Git Delete Branch
You want to delete stale branch
            
              
                $ git branch -d branch_name
                $ git push origin --delete branch_name
              
            
          
        
        Delete Local Branch
To delete the local branch use:
            
              
                $ git branch -d branch_name
              
            
          
        
        Note: The -d option is an alias for --delete, which only deletes the branch if it has already been fully merged in its upstream branch. You could also use -D, which is an alias for --delete --force, which deletes the branch "irrespective of its merged status." [Source: man git-branch]
