Works with the majority of whois info; for some that won't, you may have to compromise:
domain=google.com; for a in $(whois $domain | grep "Domain servers in listed order:" --after 3 | grep -v "Domain servers in listed order:"); do echo ">>> Nameservers for $domain from $a
Note that this doesn't work as well as the first one; if they have more than 3 nameservers, it won't hit them all.
