        The su command is used to become another user during a login 
        Invoked without a username, su defaults to becoming the 
superuser. The
        optional argument - may be used to provide an environment similar to
        what the user would expect had the user logged in directly.

        Additional arguments may be provided after the username, in 
which case
        they are supplied to the users login shell. In particular, an 
        of -c will cause the next argument to be treated as a command by 
        command interpreters. The command will be executed by the shell
        specified in /etc/passwd for the target user.

        You can use the -- argument to separate su options from the 
        supplied to the shell.

        Stupid as I am, I could not recall what su is and what it does. 
So being stupid I RTFM which in this case you get from using "man su".  
Now I know and so do you :-)
