PowerTip: Find Out From Whence a Command Comes

Summary: Find out information about where a Windows PowerShell command comes from by looking at the module information.

 I need to find out who authored a cmdlet. How do I go about finding out this information?

 The first thing you need to do is to find the module that supplies the cmdlet. You can use the Get-Command cmdlet to do this. Next, you need to use the Get-Module cmdlet to obtain the author or company information from the module. These commands appear here by using the gcm alias for Get-Command and using the Get-WsusUpdate cmdlet as an example.

PS C:\> Get-Module (gcm Get-WsusUpdate).modulename | select author, company*, version

Author                       CompanyName                 Version
