Hi, I’ve got a regex issue I am trying to figure out. The situation is I need to pull a file from several servers and return everything past a particular point in that file. The module selection is limited to what is available in a default install. The problem I am having is the regex works the first time. It only returns what I requested, but when it moves on to the next server, and every server thereafter, it returns the entire file. I’ve banged my head at this for the past day or so and just can’t seem to get anywhere. The code is below, generalized for this example.

#!/usr/bin/perl
use strict;
my $server;
my $usrallow = "/etc/opt/quest/vas/users.allow";
my @ssh;
my $line;

foreach $server(@ARGV) {
    print "getting cgrpfile from $server\n";
    @ssh = `ssh $server /bin/cat $usrallow  `;
    foreach $line (@ssh) {
        if ($line =~ /line/../\\Z/) {
        print $line;
        }
    }
   }

The output is below, again somewhat generalized
