Get-Unique - Powershell 2.0 CmdLet

Microsoft Windows PowerShell is a command-line shell and scripting tool based on the Microsoft .NET Framework. It is designed for system administrators, engineers and developers to control and automate the administration of Windows and applications.

More than hundred command-line tools (so called "cmdlets") can be used to perform system administration tasks and Windows Management Instrumentation (WMI). These cmdlets are easy to use, with standard naming conventions and common parameters, and standard tools for piping, sorting, filtering, and formatting data and objects.


Short description
Returns the unique items from a sorted list.

Get-Unique [-AsString] [-InputObject <psobject>] [<CommonParameters>]

Get-Unique [-OnType] [-InputObject <psobject>] [<CommonParameters>]

The Get-Unique cmdlet compares each item in a sorted list to the next item, eliminates duplicates, and returns only
 one instance of each item. The list must be sorted for the cmdlet to work properly.
