no real tutorials that i know of. you can always hit sun.com and look in the
admin resources for script examples. or pick up unix in a nutshell from borders or
amazon.
or you can just search google for shell or scripts and figure it out from the learn by
butcher method. there are other how-to and shell specific books for each type
out there to help get you going.
