Thank you all for replying to my stupid little problem :)
I have done this test on a P3 500MB ram and here are the results:
(debian 2.6.13-f4). The solution is obvious. :) Perl couldn't use it due
to memory restrictions.

$ ls -lh /var/import/helpdeskreport.txt.out
-rw-r--r-- 1 ykanello ykanello 291M 2005-12-08
13:16 /var/import/helpdeskreport.txt.out

$ time <command> ykanello !$
