Challenge Description

Learn the basics of PowerShell and PowerShell Scripting

Video Highlights

Powershell is the Windows Scripting Language and shell environment built using the .NET framework.

This also allows Powershell to execute .NET functions directly from its shell. Most Powershell commands, called cmdlets, are written in .NET. Unlike other scripting languages and shell environments, the output of these cmdlets are objects – making Powershell somewhat object-oriented.

This also means that running cmdlets allows you to perform actions on the output object (which makes it convenient to pass output from one cmdlet to another). The normal format of a cmdlet is represented using Verb-Noun; for example, the cmdlet to list commands is called Get-Command

Common verbs to use include:


  • Get
  • Start
  • Stop
  • Read
  • Write
  • New
  • Out

Using Get-Help

Get-Help displays information about a cmdlet. To get help with a particular command, run the following:
