-c FILE --config=FILE

-h HOST --host=HOST

-p PORT --port=PORT

-f --force-lookup

-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

-s --no-whoisservers
disable the built-in support for whois-servers.net.

of the default dump display.

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

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.
