Hello monks!

I am having a bit of trouble with this script and I do appreciate your putting up with various iterations of it over the past few days. As you'll see I changed my approach from trying to work directly with the rather verbose output of this networking device (the 3par I've been carping about) I decide it might result in less headdesking if I dumped the output to a file and tried to parse that. And not for nothing but I've recently discovered the joys of perltidy.:-)

The trouble I'm currently facing is that I am having some trouble assigning the text to a hash. It starts spitting out quite a lot of output. I will include that at the end.

Without further ado, here is my latest attempt:

#!/usr/bin/perl
use strict;
use warnings;
use IO::Pipe;
use IO::Handle;
use IO::File;
my $system;
my @systems = ( '3par-S400', '3par-E200' );
open( MYFILE, '>>data.txt' );

foreach $system (@systems) {

    my $output = run_command($system);
    while (<$output>) {
        next if (m/^$/);
        last if (m/^Press.*/);
        print MYFILE $_ . "\n";
    }
}

close(MYFILE);

open( MYFILE, '<data.txt' );

while (<MYFILE>) {
    next if (m/^$/);
    last if (m/^Press.*/);
    my ( $line, %seqs, $sequence, $date, $orig, $desg, $body );
    if ( $line =~ /(\d+\-\d+\-\d+\s\d+\d+\ d+\ +)/ ) { $date = $1; }
    else { $seqs{$sequence} = "$date;$orig;$desg;$body"; }
}

sub run_command {

    my $user      = 'gmon';
    my $system    = shift;
    my $protocol  = 'ssh';
    my $ssh_flags = "-l $user";
    my $command   = "statvv -ni";
    my $space     = " ";
    my $do_command =
      $protocol . $space . $ssh_flags . $space . $system . $space . $c
+ommand;
    my $cmd = IO::Pipe->new;
    $cmd->reader($do_command);
    return $cmd;

}

close(MYFILE);

And this is a sample of the output I'm experiencing:
