The Standard Interface for Every Server, Pipeline, and Container
Linux and Bash are the common substrate of modern software infrastructure. Whether you are writing deployment scripts, debugging a production incident over SSH, or building CI pipelines, you work in the shell. This track teaches the Linux command line and Bash scripting from first principles — navigating the filesystem, managing processes, handling permissions — through to the scripting patterns used in real DevOps and systems engineering work.
What You Will Learn
You will start with shell navigation and essential file commands, then move into environment variables, I/O redirection, and process management. Core scripting topics include control flow, functions, modular libraries, and robust error handling. You will work with grep, regular expressions, awk, and sed for text processing, and with jq and yq for structured JSON and YAML data. Later courses cover SSH mastery, cron-based automation, log analysis, system administration scripting, and writing testable Bash with CI integration. The final courses address secure Bash hardening and scripting patterns for Docker, Kubernetes, and cloud environments.
The Learning Path
Twenty-two courses span A1 through C2. The track opens with Linux Fundamentals: Navigating the Shell and Introduction to Bash Scripting, builds through B-level courses on parallel execution, advanced text processing, and Data Wrangling with awk, then reaches C1 with Linux System Administration Scripting, Log Analysis and Observability Pipelines, and Testing and CI for Bash Projects. The two C2 capstone courses — Hardened and Secure Bash Scripting and Bash for DevOps, Containers & Cloud — bring production-grade discipline to everything you have built.
How It Works
Each course is split into short, focused lessons you complete in the built-in shell editor with real-time feedback. An AI tutor is available whenever you get stuck, and every exercise runs against real command-line scenarios so the skills transfer directly to your terminal.
