Delete git branch
The basic command syntax for deleting branch is:
git branch (-d | -D) [-r] <branchname>...
Note that each local branch has a corresponding upstream branch from the remote: origin
The simplest form of the command deletes a local branch:
git branch -d dev
If you delete a branch that only exists locally, with unmerged changes, you’ll lose those changes. Therefore, git will refuse to delete a branch in such a situation, by default:
error: The branch dev is not fully merged.
If you are sure you want to delete it, run git branch -D dev.
So, you need to use:
git branch -D dev
To remove remote branch you need to use git push command along with the -d flag.
