Updated: 04/26/2017 by Computer Hope
xIRC is a graphical IRC client for Unix and Unix-like operating systems, such as Linux. It is written in C++ using the QT library. It offers separate windows for each conversation, supports DCC file transfers, and a color system similar to the popular IRC client mIRC.
It comes packaged with many popular Linux distributions, or it can be downloaded from the official project page, xirc.sourceforge.net.
