Always check the return codes of system calls. Good error messages should go to STDERR, include which program caused the problem, what the failed system call and arguments were, and (very important) should contain the standard system error message for what went wrong. Here's a simple but sufficient example:
opendir(D, $dir) or die "can't opendir $dir: $!";
Line up your transliterations when it makes sense:
tr [abc] [xyz];
The above should be aligned since it includes an embedded tab.
Think about reusability. Why waste brainpower on a one-shot when you might want to do something like it again? Consider generalizing your code. Consider writing a module or object class. Consider making your code run cleanly with use strict and -w (or use warnings in Perl 5.6) in effect. Consider giving away your code. Consider changing your whole world view. Consider... oh, never mind.
use strict
-w
use warnings
Be consistent.
Be nice.
