I'm reluctant to let this go, but a 'proper' answer would have to be of the, "I wouldn't start from here, " type. You've used Perl as a scripting language, which it isn't. Perl's very good at doing anything you need on a platform-independent basis, and shelling out with 'system' calls or backticks is almost never necessary and makes the whole program platform and shell-specific. If this is even a semi-permanent piece of software then, if I were you, I would let the group blitz it just to show you what can be done. You might even want to see that anyway as a learning exercise.
