	Thanks for your reply. I have a user id that is in the wheel group.
su and get prompted for the user id's password after which I get 
returned to the command line. Running the script with the mkdir command 
embedded still returns Permission Denied message. I have read the su man 
page to no joy. Could you please explain the sequence of events to get 
su to work.



If I've got the correct impression of it, to be in the wheel group, able you
to su to root, meaning get root privilieges.
BUT you have to know and use the root password.
If you have installed the "sudo" port, which is very easy to config, just by
removing some "hash #" marks some common privilieges of the wheel group, to
obtain almost "root power" configurable by you. And also configuarable is,
if you like the group to use their own passwords or none, just belonging to
the wheel group, when issuing the sudo command.
According to my humble understanding, just belonging to the wheel group
without further configuration, don't get you much more.
