Hello, I need to end the "do" statement with user intervention. My idea is to do this with "until" after the }} but I am unsure of how to get the until in there and accept CRTL-C as the exit. If there is a better way, let me know. Thank you in advance for your assistance. 
use strict;

my $line;

chomp($line = <stdin>);


if ($line eq "\n") {
    print "There was no port number!\n";
} else {
    do{{
        $line;   
        system ("netstat -an | grep $line \n");
                system ("sleep 10");
        redo;
        }}
    }
