What is cmdlet? - Definition from WhatIs.com
Part of the Microsoft glossary:

A cmdlet (pronounced "command-let") is a lightweight Windows PowerShell script that performs a single function. A cmdlet, which is expressed as a verb-noun pair, has a .ps1 extension.

Although Windows PowerShell includes more than two hundred basic core cmdlets, administrators can also write their own cmdlets and share them. Each cmdlet will have a help file that can be accessed by typing Get-Help CmdletName-Detailed.  The detailed view of the cmdlet help file includes a description of the cmdlet, the command syntax, descriptions of the parameters and an example that demonstrate use of the cmdlet. 

Popular basic cmdlets include:




 get the current directory


 change the current directory


 copy files


 remove a file or directory


 move a file


 rename a file

 New-Item create a new empty file or directory
