Parsing.co.uk whois avec awk

Je me demande si quelqu'un pourrait me dire pourquoi ces awk ne fonctionnent pas, ils devraient fournir le registraire et la date d'expiration :

${AWK} -F: '/Registrar:/ && $0 != ""  { getline; REGISTRAR=substr($0,2,17) } END { print REGISTRAR }'

Et

awk '/Expiry date:/ { print $3 }'``
