These are the RAW commands supported by this server. a client usually supports other commands not in this list. Commands are typed with a /prefix.
commonly used commands
privmsg (target) (message) (type /msg in client)
target can be a nick, a #channel, or nick@server (means send to nick, but only if he's on that server).
For Operators, target can also be $servermask or #hostmask to broadcast a message.
notice (target) (message)
Send a notice message. the reason for notice messages is because an automation (bot) should never reply to them. Therefore, a notice is recommended for broadcasting.
Changes your nick. If another user is using this nick already, or if the nick is invalid forbidden, an error returns.
Joins a channel. If the channel is mode +k, give the key also. "/join #chat key". multiple channels can be joined by "/join #chat,#second"
part (channel) [reason]
Leaves a channel. "/part #chat,#other bye bye". A reason/comment is optional.
mode (channel) ([+|-]b|c|i|k|l|m|n|o|p|s|t|v|x|) (nick|ban mask)
Chanops only. Changes channel modes. examples: "/mode #channel +sl 10" secret, maximum 10 users. "/mode #channel +o nick" give someone operator status.
Stop irc session, disconnect from the server. the reason/comment is optional.
topic (channel) [(topic)]
Without parameter, shows the channels topic. otherwise, changes the channel topic, if you are allowed to do so.
invite (nick) (channel)
Invite a user to a channel. If the channel has mode +i, only channel operators can use this command.
kick (channel) (nick) [(reason)]
Only by channel operators. Remove a user from the channel by force. the comment/reason is optional. /kick should be used carefully.
These commands allow a message to be forwarded to services on the net; to be used, the target needs to be set by the administrator. works like: "/chanserv help" -> "privmsg email@example.com help"
Can be used to tell others you're away. They'll see the message on /whoising you, or when they send you a message.
silence (nick|(-|+)mask) Blocks private messages at the server, and therefore can be more powerful than /ignore. example "/silence +*!*@*.lame.com" adds a mask. "/silence -*!*@*.lame.com" removes the mask again.
information request commands
ison (nick) [(nick)]
Request information on if the users with those nicks are online. example: "/ison Foo Bar" -> reply: "Foo" is online.
whois (nick mask)
Request more detailed information about a user. Tells if the user is away, if he's IRCop, his userid and host. the public channels he is on.
Wildcards can't be used here. /whowas shows info about a user who recently left irc, or changed his nick.
who (mask) [o]
Searches for users. If the full nick isn't given, invisible users are not listed. The optional o parameter lists only IRCops. example: "/who *.aol.com", "/who #channel", "/who 0 o"
Lists channels which are not secret or private, with their topic. if the channel parameter is given, only the channel with that name is returned.
Shows the users which are on the given channel, or if no channel is given, it shows all channel/user relations. Secret/invisible information is not returned in the list.
userhost (nick) [nick]
Shows the userid@host of the user with the given nick.
lusers Shows how many users are online, and the number of operators, channels, and servers.
links [(mask) [(remote server)]]
Shows all servers on the net, with their "full name" and their hopcount
map [(remote server)]
Similar to /links but an ascii-map is drawn by the server which represents the links. Shows how many clients are on each server.
Similar to traceroute. Can be used to locate lag between 2 servers in the route.
Shows the time of the server, and the bias from UTC (timezone). Also the server's timestamp is returned, but most clients don't display it.
Shows what version the irc server is running
stats (parameter) [(server)]
Shows configuration and statistics information about the server.
Shows admin info, the location and the email address, if set.
Shows information about the irc server software.
Shows the server's Message Of The Day.
help Shows all the server's supported commands.
IRC Operator commands
oper (uid) (password)
This command is used to gain IRC Operator status. Your mask, the uid, and the password are matched against all O:lines, if one matches, the /oper succeeds.
kill (nick) (reason)
Remove a user from irc by force. Should be used carefully.
connect (servermask) [(port) [(remote server)]]
Connect to a server. The server must be listed in the configuration.
example: "/connect second.server.name". "/connect third.server.name 6667 second.server.name"
squit (servermask) [reason]
Disconnects a server, and everything behind it, from the network.
example: "/squit third.server.name This connection lags, rerouting."
rehash reloads the configuration.
restart Stops the server, and starts it again. Use with care, this command breaks all server/client connections and re-sets the uptime.
die Terminates the server program. After this, physical access to the server computer is needed to start the irc server again.
gline [-|+](mask) * (duration) (reason)
Without parameter lists G-lines. example: "/gline +*bot*@*.isp.com 1000 no bots allowed" adds a G-line which lasts 1000 seconds. IRCops can or can't set global g-lines this way, depending on the server's configuration.
svsnick (old nick) (new nick)
changes someone's nick by force. This can be used by, for example, nickserv.
Sends a wallops message. This can be read by one who has mode +w (in practice, this are other IRCops.). depending on a setting, it can or cannot be read by users.
Sends a wallusers message, a wallops which can be read by everyone who has +w set.
change channel modes by force (if you're not chanop). same parameters as /mode
clear channel modes.
rarely used commands

ping (text) (forward)
pong (text) (forward)
ping and pong are used to poll if the connection is still alive.
error (error message)
