Why won't the following work? I have also tried placing the shell command in quotes with a pipe "|" appended but that throws an exception. I would like to use Shell but if I can't for whatever reason I will resort to using the usual syntax for doing what I need to get done here (ie open(PID,"/usr/bin/ps args |") or....

#!/usr/local/bin/perl -w
use strict;
use Shell;
.
.
.
    open(PID,ps("-u gvc"))   # doesn't work.
        or die("Cannot open pipe for command: ps\n");

I am thinking this doesn't work because the Shell module doesn't pipe to the open() command. If this is the case, is there a way to make Shell.pm pipe?
