Not sure, but I got an illegal divide by zero error when running your example.

I'll play around with your code and see if I can get it to work.

$code or die
Using perl at
The Spiders Web

error on getting (stat)[11] could get you a division by zero. i don't have any win32 machines to test this snippet on them, so good luck :)
on linux and solaris it works ok, outputs exactly the same as du -b. :)
(one quick solution w'd ofc be an 'and' between those two lines in my subroutine)
