hi guys, I would like ask why my script is not working as expected, everthing is working good excep the line that exec system ......, it is strange but if I exec the line on a separate script it works and do the job, any help would be preciated.. following , the code

#!/usr/bin/perl -w
use strict;
use File::Tail;

my $file = File::Tail->new(
        name =>'/var/log/dhcpd.log', 
        interval => 1, 
        maxinterval => 1, 
        resetafter=> 5, 
        );





  while (defined(my $line=$file->read)) {
         print $line,"\n"; 
                if ($line =~ /^(.*) mdz-shaper1 dhcpd: DHCPACK on ([0-
+9\.]+) to ([[:xdigit:]:]+).* ([0-9\.]+)/) {
                        my ($date,$client_ip,$client_mac,$master_ip) =
+ ($1,$2,$3,$4);


                system "sed -i '/$client_mac/d' /opt/btb_webservice/ve
+r3/lease_list.txt";
                if(($client_ip)&&($client_mac)&&($master_ip)){
              system 'echo "'.$date.' '. $client_ip.' '.$client_mac.' 
+'. $master_ip.'"'.' >> /opt/btb_webservice/ver3/lease_list.txt';
                }
        }
