I would recommend File::ReadBackwards ! (it is like the "tac" program
in that it will read the file in reverse line order) - so you need to
take that into account - used it to read in the last 1000 lines then
perhaps you will reverse() the array you fetch.
If you don't want to install it from CPAN you could open a pipe
from "tac|" or just "tail -1000".
NAME
File::ReadBackwards.pm -- Read a file backwards by lines.
SYNOPSIS
use File::ReadBackwards ;
