Windows PowerShell is a Windows command line shell designed specifically for system administrators. Windows PowerShell includes an interactive prompt and a scripting environment that can be used independently or in combination.
Unlike most shells, which accept and return text, Windows PowerShell is based on the Common Language Runtime (CLR) .NET Framework and the .NET Framework and accepts and returns .NET Framework objects. This fundamental change in the environment offers completely new tools and methods for managing and configuring Windows.
Windows PowerShell introduces the concept of cmdlet (pronounced “command-let”), a simple, single-function command-line tool embedded in the shell. You can use each cmdlet separately, but their power is achieved when you use these simple tools in combination to perform complex tasks. Windows PowerShell includes more than a hundred basic core cmdlets and you can write your own cmdlets and share them with other users.
Like many shells, Windows PowerShell gives you access to the file system on your computer. In addition, Windows PowerShell providers allow you to access other data stores, such as the registry and digital signature certificate stores, as easily as you access the file system.
This introductory guide provides an introduction to Windows PowerShell: language, cmdlets, providers, and the use of objects.
