Linux fwhios command
The Linux fwhios command is used to find and display user information.
This command functions somewhat like the finger command; it finds and displays user-related information for a specified account. The difference is that the fwhois command queries the WHOIS database at Network Solutions. The account name must be registered there to be found, and names are not case-sensitive.
