How do I delete Ubuntu users?

Ubuntu Delete users are also operating under the terminal, it is important to note that if you want to delete the user is currently logged in, is deleted, you must log off the current user to switch to another user to delete. For example, just now I set up a new user for yangming user, for example I now use User yangming landed on the desktop, at this time if I want to delete yang this user, is deleted. The correct way to do this is, I write off Yang, and then use root to log on to the desktop, and then delete yangming.
