## About the Event
This talk is for all of us who feel like we never learned Bash properly. The goal is to increase our self-sufficiency in writing Bash. We'll start with some basic Bash commands, but move quickly to combining commands, scripting, error handling and resources for teaching yourself more.

Audience: This should interest folks working in DevOps or developers doing repetitive file tasks as well as in cybersecurity and more.
