Lesson 1 Scripting
Scripting Foundation: Why Automate Understand when scripting helps, how to plan a safe script, and how variables and conditionals make repetitive work reusable.
Lesson 2 Scripting
PowerShell Essentials Write and run small PowerShell scripts using variables, conditionals, loops, and the object pipeline.
Lesson 3 Scripting
Bash Scripting Essentials Write and run small Bash scripts using a shebang, variables, conditionals, loops, and exit codes.
Lesson 4 Scripting
Scripting: Files & Text Processing Use redirection, pipes, and a few core text tools to inspect, filter, reshape, and save command output.
Lesson 5 Scripting
Task Automation Schedule a small script safely with Windows Task Scheduler or Linux cron, and understand when systemd timers are worth learning next.
Lesson 6 Scripting
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.
Lesson 7 Scripting
Scripting Lab: Backup Automation Use robocopy or rsync to synchronize a practice folder, log the result, and understand why mirror operations need caution.
Lesson 8 Scripting
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.
Lesson 9 CLI Intensive & Capstone
CLI Intensive 1: Navigation Speed Drill Build fast, accurate terminal navigation habits so common filesystem work becomes fluent without sacrificing correctness.
Lesson 10 CLI Intensive & Capstone
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.
Lesson 11 CLI Intensive & Capstone
CLI Intensive 3: One-Line Power Use concise one-line commands for safe operational work while preserving dry-run habits, verification, and reversibility.
Lesson 12 CLI Intensive & Capstone
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.

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.

Apps and Packages Script Fails with Permission Denied

Use this when a script cannot execute or access what it needs, and you need to separate file execution, path permission, identity, and interpreter issues.
