Deep Dive: Writing a Twitch Chat Bot in Bash

A hands-on walkthrough of building a Twitch chat bot entirely in Bash, using IRC as the underlying protocol. Covers connecting to Twitch's IRC server via netcat, OAuth authentication, parsing incoming messages with grep and cut, responding to PING/PONG keepalives, and creating a circular pipeline using mkfifo named pipes so the bot can both read and write to the IRC connection. Ends with a complete working script that responds to chat commands like !ping.
