http://osxdaily.com/2007/10/29/how-to-add-a-user-from-the-os-x-command-line-works-with-leopard/
It works great.
But how to create new group?
回答1:
"System preferences" -> "Accounts" -> "+" (as if you were adding new account) -> Under "New account" select "Group" -> Type in group name -> "Create group"
