The second thing I would check to see if any shelling out can be replaced by an available perl function. I recently wrote a program that required that the date/time stamps in a log file be updated. For this, I made the mistake of relying on shelling out

This one particular piece of advice is very good. A peave of mine is when I see people who write Perl scripts and all the work in them is done by using system() calls. What is the point in writing a Perl script if you're not going to use the Perl functions? You might as well write the thing in shell.

Spawning system calls does take more resources and thus it behooves the Perl programmer to try and code the functionality they want using Perl built-ins and modules.

gj! ++ on this one.
