% Whoisd Server Version: 3.15.0
% Usage: whois [options] [[type] value]
%
% Options:
% -r Switch off recursion. Only the object which is primary target
% of query is returned.
% -T type Type of object to lookup (domain, nsset, keyset, contact, registrar).
% There may be more types separated by comma without spaces
% between them. The types are case-insensitive.
% -i attr Lookup object by its attribute. Attribute can be any of
% attributes from object templates marked by flag "inverse key".
% Attribute name is case-insensitive.
% -q version Returns version of whois server.
% -q indexes Returns list of attributes which can be used in search. The
% attributes have form object:attribute.
% -q templates Returns templates for all five object types.
%
% There's yet another way how to specify a type of object to lookup. Just
% prefix the object's identifier with the name of a type. The following two
% examples are equivalent:
%
% $ whois -T domain nic.cz
%
% $ whois "domain nic.cz"
%
% The -q parameter can be used only once and not in combination with any
% other option. The -i parameter can be used only once.
