Check if a domain is available to register (uses DNS before WHOIS to be fast) - supports .com,.net,.org,.co.uk - inspired by foca/giles http://gilesbowkett.blogspot.com/2009/02/simple-bash-domain-availability.html
#!/bin/bash

# Fast, domain name checker to use from the shell
# Use globs for real fun:
# domainavailable blah{1..3}.{com,net,org,co.uk}
