Domainerator (ex-domain-anagrams) combines words plus TLDs (top-level-domains) to form domain names for all available combinations and checks them agains a specified DNS server to see if the domain name is available for registration.
The motive for the name change is because it’s not exactly an anagram generator and I had no reason to make it that way because the possibility of getting an interesting word with anagrams is unpredictable.
It not only had it’s name changed. It’s now a RubyGem also. This facilitates his usage.
To install it you only need to run this command:
$ sudo gem install domainerator
Automaticaly the domainerator can be called directly:
$ domainerator -h
