Hi Monks, Im playing with DIG command in PERL and wanted to send email to someone when the A-record result is not as expected. My script for DIG is below: 
#!/usr/bin/perl -w

use strict;

open(INPUT_FILE, "<HOSTLIST>") or die "Cannot open: $!";
my @array = <INPUT_FILE>;
close(INPUT_FILE) or die "Cannot close: $!";

for my $line (@array) {
    my @output = `dig A $line`;
    print("="x50,"\n");
    print ("@output\n\n");
}

Then i run this script on a cron and piped the result to a file which i tailed to be shown in my terminal. Now it's difficult to notice if the resulting A record changed. I have to be glued to the terminal all the time. I was thinking maybe, if the result is not as expected, the script can email and notify me. Is that possible? Thanks..! n0jp7
