Irssi

The command line IRC client. Irssi is FOSS (licensed under the GPLv2) and is available for Linux, BSD, Solaris, Apple and with Cygwin on Windows. It was developed by Timo Sirainen and was released in the beginning of 1999. It is highly customizable, for example with themes and it is possible to to use other instant messaging communication through it.

Installing

With other package managers, distros and platforms, please see the following link.

With apt:
sudo apt-get install irssi

It is rather light-weight, being only 2 392 kB on disk.

Getting around

Connecting

There are several IRC servers still alive and going strong. In this example we shall be connecting to the closest freenode server, located in Finland. Physical distance is not an issue nowadays, but imagine being stuck on a 56 kB modem with top speeds through dial-up and the copper wire being about 12 kB, maxing out at 30 kB, if local.

  • Open terminal (Ctrl+Alt+T) and type: irssi
  • /connect rajaniemi.freenode.net Closest freenode server.
  • /join itcollege

Joining channels usually requires a #-sign, for example #mozilla. Irssi adds it behind the scenes so it can be omitted.

Window Switching

Alt+# combination is used for window switching. For more than nine windows, the row below numbers will be used, for example key combination Alt+q etc. A window can be changed via command as well -- /window #. To close window, type /wc #

Channel and user configuration

Name

Default nickname (under Ubuntu) will be the computer username. To change it type /nick new-username

Nickname registration is beneficial if one is planning on staying for longer. Also registration prevents nickname abuse.

/msg nickserv REGISTER <password> <email>

Channels (chat rooms)

  • To list all chat rooms type /list Might not be a good idea to do, considering there are about 12 000 channels. To search for a specific channel might be more useful to search via browser or know beforehand what channel you want to join.
  • Joining you can omit the number sign (#) /join itcollege
  • If the channel is unregistered, connected user will receive op (+o more info below) upon entering. Channel can be registered by following command /cs register #channel channelpassword channeldescription
    • Channelpassword is required to get or give channel ownership access.
    • Channeldescription is also required, containing description (duh) or channel purpose.
  • Away message: /away msg
  • Quit message: /quit quitmsg
  • User query: /q <nick>
  • List users in a channel: /n
  • Private message a user: /m <nick> message
  • Display a channels topic: /topic
  • Perform an action: /me scratches his nose will look like <nick> scratches his nose
  • To mark yourself as away: /away away_message

This was a short introduction to IRC and Irssi. So far the best program with minimal GUI that helps user to concentrate on the most important part of IRC - text.
