## [Module 1: Meet PowerShell](https://www.ask-codey.com/courses/powershell-in-depth/modules/1)

What PowerShell is and how to install and open it, how its commands are named and how to find help for any of them, and finding your way around a computer: where you are, what is there, how to get somewhere and how to read a file.

## [Module 2: Working with Files](https://www.ask-codey.com/courses/powershell-in-depth/modules/2)

Make, copy, move, rename, zip and delete files and folders, many at once, with -WhatIf before anything that removes; write to files, edit them in the terminal, and watch a log grow.

## [Module 3: Objects and the Pipeline](https://www.ask-codey.com/courses/powershell-in-depth/modules/3)

PowerShell's big idea: everything it shows you is an object with properties. Filter, sort, count, group and act on files and programs with the pipeline, and search text and files.

## [Module 4: Working with Data](https://www.ask-codey.com/courses/powershell-in-depth/modules/4)

Turn spreadsheet exports, JSON settings files and web APIs into objects, then into clean data and reports.

## [Module 5: PowerShell, Your Way](https://www.ask-codey.com/courses/powershell-in-depth/modules/5)

Variables, text, numbers and dates, environment variables and PATH; the execution policy, your profile, aliases, a prompt in your colors, apps and modules; and the shortcuts that make you fast.

## [Module 6: Scripts Are Applications](https://www.ask-codey.com/courses/powershell-in-depth/modules/6)

A script is an application: write .ps1 files in VS Code, run them from anywhere, give them parameters, make decisions, repeat work, handle errors and debug them.

## [Module 7: Building Real Tools](https://www.ask-codey.com/courses/powershell-in-depth/modules/7)

Turn scripts into tools that behave like PowerShell's own commands: advanced functions with validation, pipeline input, -WhatIf and help, objects of your own, saved data, and a module with tests.

## [Module 9: The Developer's PowerShell](https://www.ask-codey.com/courses/powershell-in-depth/modules/9)

The scripts every software project has, calling other programs, keeping secrets out of scripts, using .NET directly, sharing your tools, and knowing when a script should become a program.
