Windows PowerShell



Windows PowerShell is a command-line shell and scripting language designed especially for system administration. Its analog in Linux is called Bash Scripting. 

Built on the .NET Framework, Windows PowerShell helps IT professionals to control and automate the administration of the Windows operating system and applications that run on the Windows Server environment. 

Windows PowerShell commands, called cmdlets, let you manage the computers from the command line. Windows PowerShell providers let you access data stores, such as the Registry and Certificate Store, as easily as you access the file system. In addition, Windows PowerShell has a rich expression parser and a fully developed scripting language. 

So in simple words, you can complete all the tasks that you do with GUI and much more.

A cmdlet or "Command let" is a lightweight command used in the Windows PowerShell environment. The Windows PowerShell runtime invokes these cmdlets at command prompt.
