hello fellow monks, i wrote this little script to check for a remote webserver's general information. after using it a few times i noticed that sometimes it caught the sites html and printed it to the screen, which wasn't in my plan. after that i added a bunch of regex to catch the lines i wanted. basically, it's really clunky and i was just wondering you you could open my mind to a much simpler method. i'm just a novice so please forgive my obvious mistakes. thanks. 
use IO::Socket;
if ($#ARGV != 0) {
die "usage: perl $0 [hostname]\n";
} else {
$host = $ARGV[0];
}
$socket = IO::Socket::INET->new(
    Proto => "tcp",
    PeerAddr => $host,
    PeerPort => 80,) or die $!;

$socket->autoflush(1);
print $socket "HEAD / HTTP/1.0\015\012\015\012";

while (<$socket>) {
