Wow, awesome! I implemented that into my code, and that seems to work great! Thanks!

I do have a question, though. I'm not sure what the line: "for my $buf ( $buf{$fh} )" is doing. Is the hash "%buf" getting initialized as the $buf variable gets populated with the sysread calls? That's the only line in the code that I'm struggling to understand. :/

Thanks again!

    It just makes $buf an alias for $buf{$fh} so I don't have to type the {$fh} part over and over.

      Ah, makes sense. Thanks again =)
