If you find yourself doing lots of system(), backticks, and lists-of-lines in Perl, it's probably best redone in shell. I learned Perl first and learned to regret it, when I realized my scripts were 99% shell with a thin topping of perl and were cut in half by leaving out the Perl.
That can probably be handled in one shell and one or two external commands, rather than perl and a shell(every time you use system or backticks, you're running a new shell and four external commands if you'll explain what you're trying to do rather than the way you want to do it.
What are you actually trying to do here? What output do you get from /usr/ucb/ps auxwwe, and what output do you want from your script?
