jwhois - Man Page

client for the whois service


jwhois [ Options ]... [ QUERY ]


jwhois searches Whois servers for the object on the command line.

The host to query is taken from a global configuration file, a configuration file specified on the command line, or selected directly on the command line.



display version, authors and licensing information.


display a short help text.

-c FILE --config=FILE

uses FILE as a configuration file instead of the default.

-h HOST --host=HOST

overrides any hosts in the configuration file and queries HOST directly.

-p PORT --port=PORT

specifies a port number to use when querying a HOST.

-f --force-lookup

forces a query to be made to a host even if a current object is available from the cache.

-v --verbose

outputs verbose debugging information while running (use this before sending a bugreport to ensure that it's indeed a bug and not a  misconfiguration). You can increase the verbosity by giving several verbose commands to jwhois, such as -vv.

-n --no-redirect

disable features that redirect queries from one server to another.

-s --no-whoisservers

disable the built-in support for whois-servers.net.

-a --raw

send query verbatim to receiving hosts instead of rewriting them according to the configuration.

-i --display-redirections

display every step in a redirection (default is to display only the last answer).

-d --disable-cache

completely disable both reading and writing to cache.

-r --rwhois

force the query to use the rwhois protocoll instead of HTTP or whois.


asks receiving rwhois servers to display the results in the DISPLAY display instead of the default dump display.


asks receiving rwhois servers to limit their responses to LIMIT matches.

Ripe Extensions

To use the options specified in RIPE Document 157, you need to change the format of the query slightly. If you were to search for all entries in the RIPE database which lists the admin-c, tech-c or zone-c as CO19-RIPE, you could use the following command syntax:

jwhois -h whois.ripe.net -- -i admin-c,tech-c,zone-c CO19-RIPE

-- is used to separate the RIPE options from the jwhois options.
