.SH Syntax
.B whois [ \-h \fIservername\fP ] \fIname\fP
.SH Description
.NXR "whois command"
The
.PN whois
command allows you to look up people, hosts, and organizations in 
the database
kept by the Network Information Center (NIC) at SRI International.
The
.I name
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 
.I name
argument contains white space or other special characters, you must
surround it with double quote (") marks to 
prevent its interpretation by the shell.
.PP
.PP
The WHOIS server at the NIC will provide more information on doing
complex searches if you do
.EX 5
whois "?"
.EE
(note the quotes around the question mark), or even more information
if you do
.EX 5
whois help
.EE
.SH Options
.IP "\-h \fIservername\fP" 15
Specifies the whois server on a host other than the default 
(NIC.DDN.MIL).
.SH Examples
.EX 5
whois cerf
whois dec.com
whois -h ns.nic.ddn.mil knuth
whois smith
.EE
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.
