An IRC bot designed to streamline the process of posting to IRC from shell scripts, making communication more efficient and user-friendly.
Firstly, IRCcat listens on a specific IP address and port that are specified by the user. Once incoming data is received, it writes it to the designated IRC channel. This is an advantageous feature that eliminates the need to manually send messages to the channel.
Secondly, IRCcat also has the ability to transfer commands issued on IRC to a pre-determined handler program, which in most cases is a shell script. The software will then respond to IRC with the relevant output generated by the handler script. This function only takes place for commands that are directly addressed to IRCcat or commands prefaced with '?'. Users have the option to add extensions to the IRCcat software with their own scripts, maximizing the software's functionality.
Overall, IRCcat is a valuable tool for automating the transmission of messages to an IRC channel and acting upon and responding to commands received on IRC.
