About this track

PowerShell is the command line and scripting language behind Windows, Azure and Microsoft 365 administration - and it runs on macOS and Linux too. Instead of passing text between commands, it passes objects, so sorting, filtering and reporting need no text surgery at all.

You’re the new automation keeper at Emberfall Dragon Sanctuary. You’ll learn Verb-Noun cmdlets and how to discover any command, explore objects with Get-Member, manage files, then build object pipelines with Where-Object, Sort-Object and Group-Object. You’ll format text, import and export CSV and JSON, write scripts with variables, hashtables, loops, functions and modules, handle errors, automate safely with -WhatIf, and meet the best of PowerShell 7. Along the way you’ll build pipelines object by object, sort out approved verbs, and review a risky script. Exercises run real PowerShell in your browser, and the capstone has you build the sanctuary’s feeding report.

Before you start
  • No PowerShell or programming experience is required.
  • A modern browser with JavaScript enabled. To practice locally, install PowerShell 7 (`pwsh`) on Windows, macOS or Linux.
