WeeChat is a modern IRC client, based on a powerful text-driven interface. It is designed with extensibility in mind, featuring a wide array of options, plug-ins (such as spell checking) and several scripting languages. It allows for multiple connections to multiple servers. WeeChat has UTF-8 support and may use multiple character sets for encoding and decoding messages.
You will need to install the weechat package.
It should be noted that support from the WeeChat developer is only provided for the latest release and the current development version. Due to differences in the development cycles of WeeChat and Ubuntu the latest WeeChat release is seldom available from the Ubuntu repositories. In order to obtain support it might be necessary to install the latest version of WeeChat from a PPA, details of which can be found by on the WeeChat website.
WeeChat is a text-based console application, sometimes called a curses application due to the style of the user interface.
WeeChat is started by issuing the following command in a terminal window:
If Unity is being used, the keyboard the keyboard shortcut Ctrl-Alt-T will open a terminal window. In Kubuntu, a terminal can be started from the 'K' button and navigating to the Konsole application in the Applications, System menu. Other ways of opening a terminal window are dependent on the desktop environment or flavor of Ubuntu being used.
By default, WeeChat automatically connects to the Freenode network, which is used by all of the official Ubuntu IRC channels. Once connected, a unique nickname should be used and can be selected with the command:
where newNick is the new nickname. To join an IRC channel use the following command:
