- Synopsis:
- who [<switch> [<arg>] [<switch> [<arg>] ...]] [<glob pattern>]
-
- Description:
- The WHO command is used to retrieve detailed information about every
- user on irc. For each user, it returns a single line containing
- their nickname, address (user@hostname), realname (IRCNAME), what
- their current channel is (and whether they have +o or +v there),
- whether they are marked away, and whether they are an irc operator.
-
- The data returned can be filtered by the client in a number of ways.
- It can be set to return only users who are marked away, people with a
- certain username, or users on a specific server. For large queries,
- the data can also be conveniently dumped to a file for later viewing.
-
- The parameters to -end are as follows:
- $0 name of server queried
- $1 body of the query
-
- Options:
- -operators returns irc operators
- -lusers returns non-irc operators
- -chops returns channel operators
- -nick <nickname> returns info for the given nickname only
- -name <username> returns info for the given username only
- -host <hostname> returns info for the given hostname only
- -server <servername> returns info for the given servername only
- -diagnose shows contents of the who queue for the server
- of the current window
- -flush removes all entries of the who queue for the server
- of the current window
- -here returns users who are not away
- -away returns users who are away
- -line {...} executes {...} for each line of output
- -end {...} executes {...} at the end of the query
- -file <filename> compare file contents to each line of output
- -u-i show invisible users (opers only, required
- on the undernet)
-
- Examples:
- To list all irc operators on servers from foo.com:
- /who -o -s *.foo.com
-
- To list the channel operators on channel #blah, which you are on:
- /who -c #blah
-
- To list all users from Russia, saving it to a file:
- /who -h *.ru -f ru.users
-
- To list all non-opers and say something at the end:
- /who -lusers -end { echo sheesh. that's alot of lusers! }
-
- See Also:
- on(5) who; whois(2)
-
- Restrictions:
- There are some limitations to the data returned by WHO. For instance,
- it will not show users who have user mode +i set, unless that user's
- nickname is explicitly and unambiguously specified. Similarly, it
- will mask channels with mode +p set, and will not show +s channels at
- all. These limits do now apply, however, if the user in question is
- on a like channel with the querying client, or if the client is on a
- channel for which data is queried.
-
- Other Notes:
- The various command line switches detailed above may be abbreviated,
- as shown in the examples, so line as the abbreviations are unambiguous.
- For instance, -n may not be used, since it matches -nick and -name.
-
- Use of the -file switch is not recommended, unless you know that the WHO
- output will be minimal. This is because the client reads the entire file
- specified for each line of output, which is obviously quite inefficient,
- to say nothing of being rather abusing to your filesystem.
-
- The arguments from -line are identical to the arguments to on(5) who.
- In fact, -line works exactly like on(5) who. except it ALWAYS overrides
- on(5) who and disappears when the query is done. The -end is similar in
- that it overrides hooks to the 315 numeric.
-
- The -flush switch should *never* be used while a WHO request is still
- pending. The results are unpredictable. This is not a bug.
