I feel I should point out that, even without an interface, you could
expose security vulnerabilities. For instance, if you use the echo
<password>|sudo -S method, it usually displays the password that was
echoed when you look at the processes, say via ps. This is sort of a
bad thing, since any application or person could, conceptually, run
ps and immediately have the user's password. So, the concern isn't
about what can be done to your application, but rather what can be
done to the system because of the application.
You can't, so far as I know, really cause a script to logout then
back in as a different user. You could have cron use different
versions of the script that just run as different users, or you can
call su - <username> from the script, though that would entail using
interactive passwords, since I don't think su will read passwords
from stdin.
As for Wake on LAN, you might look at the tools listed here:
https://webserver.brandeis.edu/pages/view/Bio/MacOSXWakeOnLAN
One of them may lead you to a way to form a proper WOL packet,
otherwise you could try tracking down the network standard for it,
should one exist.
Good luck,
Fargo

Thanks Sam, Kem, and Fargo,
I'll give this a wack. I tried to find the answer myself so I might
have got myself screwed up some with the 'using administrators
permissions' thing - I think this is an AppleScript thing and not
Shell script.
As for security... this is not an issue. My little slave programs
have no interface so it can not be tampered with. It's only function
is listen on a particular port for specific UDP commands. Commands
can only be sent from the master program which am in control of. I'm
the administrator of a 24 Mac Lab. This is just to streamline my
job. I already can do some real cool stuff... Shut Down & Restart is
a given, but I can do a Repair Disk Permissions, move all desktop
items to the trash, empty the trash, close all Finder windows,
run/quit applications, open a specified browser to a specified URL,
sleep, wake, open/ close CD/DVD drawers, and a bunch more. I can
select a singe Mac or send to all (it's real funny sending an open
and close drawer commands to all - except for our newer Mac the
drawers open and close in unison - kind of like the scene from No
Time For Sergeants except computers and not toilets). I'm still
working on a way to logout from one account and into another using a
Shell Script and implementing a 'Wake On Lan'.
Have an Egg Nog on me... Actually have mine I hate the stuff!
