Author can't print to STDOUT on 5.8.4

Hi,

I was running this command on my perl program,

open FLOWTOOLS, "|/usr/bin/flow-cat $start |
/usr/bin/flow-nfilter -f filter.tmp -F $direction
|/usr/bin/flow-stat -Pf8 | le
ss" or die $!;

It does output something on the screen when I run it
on FreeBSD 6.1/perl 5.8.8 (while on csh)

However, when I run it on another machine Linux
version 2.6.8-2-386 Debian 1:3.3.5-13, with This is
perl, v5.8.4 built for i386-linux-thread-multi (while
on bash)

a blank screen appears shortly and then the program
immediately exits..

Any idea why this is happening?

Thanks.

First of all, FLOWTOOLS is not STDOUT.

You can't use "less" this way. "Less" is supposed to be used
on an interactive terminal. I know nothing about the
flow-tools. What are you trying to do?
