What is IRC, and how does it work?
IRC (Internet Relay Chat) provides a way of communicating in real time with people from all over the world. It consists of various separate networks (or “nets”) of IRC servers, machines that allow users to connect to IRC. The largest nets are EFnet (the original IRC net, often having more than 32,000 people at once), Undernet, IRCnet, DALnet, and NewNet.
Generally, the user (such as you) runs a program (called a “client”) to connect to a server on one of the IRC nets. The server relays information to and from other servers on the same net. Recommended clients:
-
Be sure to read the documentation for your client!Once connected to an IRC server on an IRC network, you will usually join one or more “channels” and converse with others there. On EFnet, there often are more than 12,000channels, each devoted to a different topic. Conversations may be public (where everyone in a channel can see what you type) or private (messages between only two people, who may or may not be on the same channel). IRC is not a “game”, and I highly recommend you treat people you meet on IRC with the same courtesy as if you were talking in person or on the phone, or there may be serious consequences.
Some details
Channel names usually begin with a #, as in #irchelp . The same channels are shared among all IRC servers on the same net, so you do not have to be on the same IRC server as your friends. (There are also channels with names beginning with a & instead of a #. These channels are not shared by all servers on the net but exist locally on that server only.)
Each user is known on IRC by a “nick”, such as smartgal or FunGuy. To avoid conflicts with other users, it is best to use a nick that is not too common, e.g., “john” is a poor choice. On some nets, nicks do not belong to anyone, nor do channels. This can lead to conflict, so, if you feel strongly about ownership of such things, you may prefer networks with “services” likeUndernet, DALnet, or other smaller networks.
Channels are run by channel operators, or just “ops” for short, who can control the channel by choosing who may join (by “banning” some users), who must leave (by “kicking” them out), and even who may speak (by making the channel “moderated”)! Channel ops have complete control over their channel, and their decisions are final. If you are banned from a channel, send a /msg to a channel op and ask nicely to be let in (see the /who command in the next section to learn how to find ops). If they ignore you or /who gives no response because the channel is in secret mode (+s), just go somewhere else where you are more welcome.
IRC servers are run by IRC admins and by IRC operators, or “IRC ops”. IRC ops manage the servers themselves and, on EFnet and many other networks, do not get involved in personal disputes, channel takeovers, restoring lost ops, etc. They are not “IRC cops.”
Talking, and entering commands
Commands and text are typed in the same place. By default, commands begin with the character / . If you have a graphical client such as mIRC for Windows, many commands can be executed by clicking on icons with the mouse pointer. It is, however, highly recommended that you learn to type in the basic IRC commands first. When entering commands, pay close attention to spacing and capitalization. The basic commands work on all the good clients.
Some examples are given below. In these, suppose your nick is “yournick”, and that you are on the channel #coolness.
Your friend “MaryN” is in #coolness with you, and your friend “Tomm” is on IRC but is not on a channel with you. You can apply these examples in general by substituting the relevant nick or channel names.
What you type, What happens
/join #coolness
- You join the channel #coolness.
/who #coolness
- Gives some info on users in the channel.
@ = channel op, while * means IRC op.
hello everyone
- Everyone on #coolness sees hello everyone. (You need not type in your own nick.)
/me is a pink bunny
- Everyone in #coolness sees * yournick is a pink bunny
/leave #coolness
- You leave the channel.
/whois Tomm
- You get some info about Tomm or whatever nickname you entered.
/whois yournick
- This is some info others see about you.
/nick newnick
- Changes your nick to “newnick”
/msg Tomm hi there.
- Only Tomm sees your message (you don’t need to be on the same channel for this to work).
/ping #coolness
- Gives information on the delay (round-trip) between you and everybody on.
Coolness
/ping Tomm
- Gives information on the delay (round-trip) between you and just Tomm.
/dcc chat MaryN
- This sends MaryN a request for a dcc chat session. MaryN types /dcc chat yournick to complete the connection. DCC chat is faster (lag free) and more secure than /msg.
/msg =MaryN Hi there!
- Once a DCC connection has been established, use the /msg =nick message format to exchange messages (note the = sign). DCC does not go through servers, so it are unaffected by server lag, net splits, etc.
/help
- This works in many clients. Try it!
/quit good night!
- You quit IRC completely, with the parting comment so that others see “*** Signoff: yournick (good night!)”.
NOTE: When you are not in a named channel, lines not beginning with a / have no effect, and many commands work differently or fail to work altogether.
Where to go
You can learn a lot by joining a channel and just listening and talking for a while. For starters, try these channels: #new2irc, #newuser, #newbies, or #chat.
To form your own channel with the name #mychannel (if #mychannel does not already exist), type /join #mychannel. The channel is created and you are automatically made an op.
Some smileys and jargon
:-) is a smiley face, tilt your head to the left to see it. Likewise, :-( is a frown. ;-) is a wink. :~~( is crying, while :-P is someone sticking their tongue out. :-P ~~ is drooling. (-: a lefty’s smile, etc. There are hundreds of these faces.
Here are some common acronyms used in IRC:
brb = be right back bbiaf = be back in a flashbbl = be back later ttfn = ta ta for now
lol = laughing out loud j/k = just kidding
np = no problem imho = in my humble op
ire = hi again, as in 're hi' wb = welcome back wtf = what the f--k rtfm = read the f--king manualrotfl = rolling on the floor laughing
Some advice
- Etiquette Typing in all caps, LIKE THIS, is considered “shouting” and should be avoided. Likewise, do not repeat yourself or otherwise “flood” the channel with many lines of text at once. Be sure to use correct terminology, e.g., “channel”, not “chat room”, and “nick”, not “handle”.
While in a channel, follow the lead of the channel ops there. If you antagonize them, you may be “kicked” off the channel forcibly and possibly “banned” from returning. On the other hand, some channel ops are power-hungry and may kick or ban for no good reason. If this happens, or if someone on a channel is bothering you, simply leave the channel — there are thousands of others.
- Registration On many networks. services exist for the registration of nicknames and/or channels. These services vary greatly between networks, but are useually mentioned in the server’s message of the day (MOTD) which is shown when you first connect. You can show the MOTD again at any time by typing /motd in most clients.
THe network’s home page will also detail any services offered on that network.
Nickname registration allows you to “own” a nickname, and prevent others from using it on that network. Consequently, if you try to use a nickname that someone else already has reserved on such a network, you will recieve a warning message from the network, and after a few seconds, your nickname will be changed or your will be disconnected. In the event that this happens, simply change your nickname until you find one that’s not taken. Consult the MOTD or network homepage for details if you want to register your nickname.
- Disconnected by /list? If you get disconnected when using the /list command, try switching servers, or else recent channel lists are available on the WWW athttp://www.irchelp.org/irchelp/chanlist/.
- Harrassment and attacks If someone starts harassing or flooding you, leave the channel or use the /ignore command. For more details, mIRC users see our flood protection page, ircIIusers type /help ignore. It is a good idea to set your user mode to +i (invisible) to avoid unsolicited messages and harrassment — if you are “invisible” generally only users on a channel with you can determine what nick you are using.
If somebody else is crashing or disconnecting you, see our Denial of Service or “Nuke” Attacks page. You can also log and report abuse when it violates server rules, which you can read by typing /motd.
More detailed help
For further information about these issues, as well as about other commands, visit the web site <http://www.irchelp.org. There you can find many help files, such as:
- FAQ (Frequently Asked Questions) for alt.irc newsgroup

At that web site you will also find more advanced information for specific IRC clients, including:
- mIRC client for WindowsLooking for other clients? The most comprehensive source of clients is at the Undernet FTP archive or Undernet WWW archive. The clients are organized into groups like Windows, Macintosh, DOS, Amiga, Java, etc.The mIRC client also has excellent built-in help files written by Tjerk Vonck (mirc@dds.nl). Select Ircintro.hlp from the Help menu.
A word of warning
- IRC scripts are sets of commands that your client will run. Many otherwise good scripts have been hacked so that if you load them, you can seriously compromise your security (someone can get into your account, delete all of your files, read your mail, etc.). There are also evildoers who try to send people viruses and other bad things. Just like in real life, don’t accept anything from a stranger. There have been many incidents of this type, not just a few. Do not ever run a script unless you know what each line does, not even if it is given to you by a friend, as your friend may not have the expertise to detect well-hidden “trojans”.
- Automatic DCC get is a very bad idea! Once it is on, you are susceptible to dangers ranging from disconnection from your server to giving someone else control of your computer. Quite a few people have run into serious problems because of the DCC autoget setting.
Special thanks to FreeSoft, prysm, hershey, turtle, Ariell, and other #irchelp helpers on EFnet for their many helpful suggestions.

List of Internet Relay Chat commands
From Wikipedia, the free encyclopedia
This is a list of all Internet Relay Chat commands from RFC 1459, RFC 2812, and extensions added to major IRC daemons. Most IRC clients require commands to be preceded by a slash ("/"). Angle brackets ("<" and ">") denote what's placed in the encapsulated field, not a literal part of the command. Arguments encapsulated in square brackets ("[" and "]") are optional and override the command's defaults.
