Hello monks!

As some of you may be aware I have bee struggling with a perl script for a few days in my attempts to parse the extremely verbose output of 3par commands.

I feel I am inching closer to my goal, but I have hit a new stumbling block. For some reason this script does not output anything at all, even tho it is loaded with test print statements. 

#!/usr/bin/perl
use strict;
use warnings;
use IO::Pipe;
use IO::Handle; 


my @systems = ('3par-S400','3par-E200');
my $system;
my $output;
my $command;

STDOUT->autoflush(1);
print "this is test statement one!\n";

foreach $system (@systems) { 

    $output = run_command($system);

    STDOUT->autoflush(1);
    print "this test is just before the while loop!\n";

    while (<$output>) {
        next if (m/^$/);
        last if (m/^Press.*/);
        my (@headers) = /\d\d:\d\d:\d\d/;
        STDOUT->autoflush(1);
        print "This is a test before the loop from insde while!\n";
        foreach my $header(@headers) {
        STDOUT->autoflush(1);
        print "this is a test\n";
        STDOUT->autoflush(1);
        print "$header \n";
        }
        
 }

    close($output);

}


sub run_command {

my $user = 'gmon';
my $system = shift;
my $protocol = 'ssh';
my $command = "statvv -ni";
my $space = " ";
#The following is bad but it works for now..
my $do_command = $protocol . $space . "-l $user" . $space . $system . 
+$space . $command; 
my $cmd = new IO::Pipe;
$cmd->reader($do_command);
return $cmd;
   
    
}

It doesn't even print any errors. Any thoughts? Thanks Monks!
