Name
whois - DARPA Internet user name directory service
Syntax
whois [ -h _s_e_r_v_e_r_n_a_m_e ] _n_a_m_e
Description
The _w_h_o_i_s command allows you to look up people, hosts, and organizations
in the database kept by the Network Information Center (NIC) at SRI
International. The _n_a_m_e can be the last name of a registered user, or
the name of a registered Internet host, or other things recognized by
the whois server. Not all users, and only a few Internet hosts, are
registered with the NIC. If the _n_a_m_e argument contains white space or
other special characters, you must surround it with double quote (")
marks to prevent its interpretation by the shell.
The WHOIS server at the NIC will provide more information on doing com-
plex searches if you do
whois "?"
(note the quotes around the question mark), or even more information if
you do
whois help
Options
-h _s_e_r_v_e_r_n_a_m_e Specifies the whois server on a host other than the
default (NIC.DDN.MIL).
Examples
whois cerf
whois dec.com
whois -h ns.nic.ddn.mil knuth
whois smith
Note that the last example, at least, will match many records (and may
take fairly long to complete). The whois server at the NIC will
automatically provide information on how to single out one record.
Remember to put quotes around strings that contain `!' characters.
