> Linux Man Page: "whois"


Search with Google


The Linux Documentation Project maintains an archive of snaphots of the (English language) core Linux manual pages that are maintained by Michael Kerrisk. Corrections and additions are welcome, but review the "Help Wanted" list, first.

Man pages belonging to programs are usually distributed together with those programs. Therefore, the core Linux man-pages mainly contains the pages for system calls and library routines, special devices, and file formats. However, it also contains documentation for a few programs, in cases where the authors or maintainers of the program do not distribute man pages themselves.

This page is part of release 3.11 of the Linux man-pages project. A description of the project, and information about reporting bugs, can be found at

jwhois - 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.

--help 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

-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.

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 -- -i admin-c,tech-c,zone-c CO19-RIPE

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