My Perl doesn't know what strlen is. Is it part of a module?
I don't think, it is a limitation of the pr

I suggest: File::Tail if you are wanting to something like tail -f, though.
Works like a champ.

Here is a basic Perl implementation of tail:

If you're having this kind of trouble, chances are you might not be properly
scoping your array. Try declaring the array using my() inside of the scope
you wish to use, for example inside of a loop. Then you won't have to worry
about whether you remembered to undef your array.

grep in perl doesn't work exactly same way as grep in *nix. It functions
differently in perl, and has better uses in perl that the *nix's grep can't
