Scripting Foundation: Why Automate

Best when you want shell fluency that helps with real work, not just syntax trivia.

Open first lesson

PowerShell Essentials Write and run small PowerShell scripts using variables, conditionals, loops, and the object pipeline. Bash Scripting Essentials Write and run small Bash scripts using a shebang, variables, conditionals, loops, and exit codes. Scripting: Files & Text Processing Use redirection, pipes, and a few core text tools to inspect, filter, reshape, and save command output.

Scripting Foundation: Why Automate Understand when scripting helps, how to plan a safe script, and how variables and conditionals make repetitive work reusable. PowerShell Essentials Write and run small PowerShell scripts using variables, conditionals, loops, and the object pipeline. Bash Scripting Essentials Write and run small Bash scripts using a shebang, variables, conditionals, loops, and exit codes. Scripting: Files & Text Processing Use redirection, pipes, and a few core text tools to inspect, filter, reshape, and save command output. Task Automation Schedule a small script safely with Windows Task Scheduler or Linux cron, and understand when systemd timers are worth learning next. Scripting Lab: System Health Report Build a small Bash or PowerShell script that records a timestamp, disk usage, memory information, and a short process summary into a readable log. Scripting Lab: Backup Automation Use robocopy or rsync to synchronize a practice folder, log the result, and understand why mirror operations need caution. Containers Intro: Docker Basics Understand the fundamental difference between Virtual Machines and Containers, and use the Docker CLI to run, manage, and network isolated applications. CLI Intensive 1: Navigation Speed Drill Build fast, accurate terminal navigation habits so common filesystem work becomes fluent without sacrificing correctness. CLI Intensive 2: Text Processing Mastery Build fast, reliable pipeline habits for filtering, extracting, and counting text without losing track of what each stage does. CLI Intensive 3: One-Line Power Use concise one-line commands for safe operational work while preserving dry-run habits, verification, and reversibility. Capstone: The Expert Challenge Use the command line to build, secure, verify, and document a small operating-system administration environment from a clean starting point.

Practice this domain

Use practice after the first lesson when you want the ideas to start feeling natural in real work.

Cron & Scheduling

Practice reading cron syntax, creating one safe scheduled job, and verifying that it ran as expected.

Open troubleshooting when this topic becomes a real issue on your computer or at work.

Automation Produces the Wrong File Output

Use this when a script runs but writes the wrong files, wrong names, or wrong locations, and you need to inspect assumptions before it causes larger damage.

Files and Storage Scheduled Task or Cron Job Does Not Run

Use this when scheduled automation never starts or behaves as if it never ran, and you need to inspect schedule, identity, environment, and logs.
