WhoisCL

WhoisCL: A simple command-line tool that will allow you to easily get information about a registered domain using a straightforward approach

WhoisCL is a simple command line tool for finding information about a domain. The software is an alternative to all the whois services available online. WhoisCL gathers all the specific information about a given domain such as name and registrar URL, email and phone, country, organization, street, city, admin name, and more.

The sole advantage of WhoisCL compared to its online counterparts is that the software is run by your computer locally and the queries will be, in theory, much faster. The tool also has a simple yet effective interface, once the whois command is given, all the results will be displayed in an easy-to-read fashion.

While WhoisCL isn't a tool for the average user, for webmasters and admin, it's pretty useful since you don't have to go to different online services to do your whois queries.
