How to use the whois command in Linux.
The Whois System
The whois system is a list of records that contain information about both domain owners and owners. The Internet Corporation for assigned names and numbers (ICANN) regulates domain name registration and ownership, but the list of records is held by many companies known as registries.
Anyone can request a list of entries. When you do, one of the registries will process your request and send you the data from the corresponding whois record.
The Whois record contains all contact information related to the person, company, or other person who registered the domain name. Some registrations contain more information than others, and some registries return different amounts of information.
A typical whois record will contain the following information:
The name and contact information of the registrant: domain owner.
The name and contact information of the registrar: the organization that registered the domain name.
The registration date: the date of domain registration.
When the information was last updated: the date when the domain information was last updated.
The expiration date: the date when the domain was released.
You can make whois queries on the Internet, but with the Linux whois command, you can search directly from the command line. This is useful if you need to perform a search from a computer without a graphical user interface, or if you want to do it from a shell script.
