List of Internet Relay Chat commands

Wikimedia list article

This is a list of all Internet Relay Chat commands from IETF RFCs 1459 and 2812. Most IRC clients need commands to have a slash ("/") before the command. Angle brackets ("<" and ">") mean what's placed in the secondary field, not a literal part of the command. Settings encapsulated in square brackets ("[" and "]") are optional and override the command's defaults.

INVITE INVITE <nickname> <channel> Invites <nickname> to the channel <channel>.[8] <channel> does not have to exist. If it does, only members of the channel can invite other clients. If the channel mode i is set, only channel operators may invite other clients. RFC 1459
ISON ISON <nicknames> Asks the server to see if the clients in the list <nicknames> are on the network.[9] The server returns the nicknames that are on the network. If none of the clients are on the network the server returns an empty list. RFC 1459

LIST LIST [<channels> [<server>]] Lists all channels on the server.[14] If the list <channels> is given, it will return the channel topics. If <server> is given, the command will be sent to <server> for evaluation. RFC 1459
LUSERS LUSERS [<mask> [<server>]] Returns statistics about the size of the network.[15] If used with no arguments, the statistics will be about the entire network. If <mask> is given, it will return only statistics about the masked subset of the network. If <target> is given, the command will be sent to <server> for evaluation. RFC 2812
MODE MODE <nickname> <flags> (user)
MODE <channel> <flags> [<args>] 		The MODE command is has two uses. It can be used to set both user and channel modes.[16] RFC 1459

They are grouped by channel name with all users who are not on a channel being shown as part of channel "*". If <server> is specified, the command is sent to <server> for evaluation.[19] RFC 1459[b]
NICK NICK <nickname> [<hopcount>] (RFC 1459)

PASS PASS <password> Sets a connection password.[25] This command must be sent before the NICK/USER registration combination. RFC 1459
PING PING <server1> [<server2>] Tests a connection.[26] A PING message results in a PONG reply. If <server2> is given, the message is sent to it. RFC 1459
PONG PONG <server2> [<server2>] This command is a reply to the PING command. It works in much the same way.[27] RFC 1459
PRIVMSG PRIVMSG <msgtarget> <message> Sends <message> to <msgtarget>. The target is usually a user or channel.[28] RFC 1459

RFC 1459

TOPIC TOPIC <channel> [<topic>] Used to get the channel topic on <channel>.[41] If <topic> is given, it sets the channel topic to <topic>. If channel mode +t is set, only a channel operator may set the topic. RFC 1459
TRACE TRACE [<target>] Trace a path across the IRC network to a specific server or client, in a similar method to traceroute.[42] RFC 1459
USER USER <username> <hostname> <servername> <realname> (RFC 1459)

USER <user> <mode> <unused> <realname> ( RFC 2812)

This command is used at the beginning of a connection to specify the username, hostname, real name and initial user modes of the connecting client.[43][44] <realname> may contain spaces, and thus must be prefixed with a colon. RFC 1459
RFC 2812
USERHOST USERHOST <nickname> [<nickname> <nickname> ...] Returns a list of information about the nicknames specified.[45] RFC 1459
USERS USERS [<server>] Returns a list of users and information about those users in a format similar to the UNIX commands who, rusers and finger.[46] RFC 1459

WHOWAS WHOWAS <nickname> [<count> [<server>]] Returns information about a nickname that is no longer in use (due to client disconnection, or nickname changes).[52] If given, the server will return information from the last <count> times the nickname has been used. If <server> is given, the command is forwarded to it for processing. In RFC 2812, <nickname> can be a comma-separated list of nicknames.[53] RFC 1459
