I'm leery of learning too much all at once so I'll stay far away from perl.

What does this do? Specify bash as the shell?

Thank you :) :) :) :)!!!!!!!!!!!!!!!!

Now I'm ready for the next stage of "scripting" :). Is there IF THEN...ELSE
functionality?

What I'd like to do is use time as a condition. e.g.

IF TIME>6 AND TIME<23 THEN...

I presume I can use something like TIME=`date +%H`

ELSE... just let the script exit. Its job is done.

Thanks, Eric.
