Other users, with only public access to that directory, can do
none of these.
You have owner access to your own main directory and sub-
directories, but public access to any directory that you specify
beginning with a $ or that you reach (using *DIR) via the root
directory.
EXAMPLE
You log on as JOEY. You will have owner access to the files and
sub-directories in the main directory JOEY. You will have public
access to the contents of the main directory PHILIP, which you
have to specify as $.PHILIP. If you specify your own main
directory as $.JOEY, instead of just JOEY, you will have only
public access to it.
