Extract a Cmdlet’s Parameters into a Collection with PowerShell

While building a script to help out a reader of this blog, I came up with a handy little cmdlet to retrieve the parameters of a cmdlet and place them into a collection.

Function Get-ParameterList

{

    [cmdletBinding()]

    Param ($Cmdlet)

        Write-Verbose "== Cmdlet: Get-ParameterList =========================="

        Write-Verbose "Parameter - `$Cmdlet: $Cmdlet"

        $List = (get-help $Cmdlet -parameter * |

            Select-Object -Property Name |

            ForEach -Process {$_.name})

 

        Write-Verbose "Sending $($List.count) Items to the pipeline."

        Write-Output $List

        Write-Verbose "__ End Function: Get-ParameterList ____________________"

    <#

    .SYNOPSIS

    Extracts cmdlet parameters

 

    .DESCRIPTION

    Extracts the parameters from a supplied cmdelt and sends then as a collection

    into the PowerShell Pipeline.

 

    .PARAMETER Cmdlet

    The name of the cmdlet whose parameters you want to extract.

 

    .EXAMPLE

    Get-ParameterList Set-MailContact

 

    Sends a collection of strings containing the names of all of the parameters

    avaliabe to the cmdlet Set-MailContact.

    #>

} # End: Cmdlet: Get-ParameterList

Adding a Comment to a GPO with PowerShell

As I'm writing this article, I'm also writing a customization for a PowerShell course I'm teaching next week in Phoenix.  This customization deals with Group Policy and PowerShell.  For those of you who attend my classes may already know this, but I sit their and try to ask the questions to myself that others may ask as I present the material.  I finished up my customization a few hours ago and then I realized that I did not add in how to put a comment on a GPO.  This is a feature that many Group Policy Administrators may not be aware of. This past summer I attended a presentation at TechEd on Group Policy.  One organization in the crowd had over 5,000 Group Policies.  In an environment like that, the comment section can be priceless.  I always like to write in the comment section why I created the policy so I know its purpose next week after I've completed 50 other tasks and can't remember what I did 5 minutes ago. In the Group Policy module for PowerShell V3, th

Return duplicate values from a collection with PowerShell

If you have a collection of objects and you want to remove any duplicate items, it is fairly simple. # Create a collection with duplicate values $Set1 = 1 , 1 , 2 , 2 , 3 , 4 , 5 , 6 , 7 , 1 , 2   # Remove the duplicate values. $Set1 | Select-Object -Unique 1 2 3 4 5 6 7 What if you want only the duplicate values and nothing else? # Create a collection with duplicate values $Set1 = 1 , 1 , 2 , 2 , 3 , 4 , 5 , 6 , 7 , 1 , 2   #Create a second collection with duplicate values removed. $Set2 = $Set1 | Select-Object -Unique   # Return only the duplicate values. ( Compare-Object -ReferenceObject $Set2 -DifferenceObject $Set1 ) . InputObject | Select-Object – Unique 1 2 This works with objects as well as numbers.  The first command creates a collection with 2 duplicates of both 1 and 2.   The second command creates another collection with the duplicates filtered out.  The Compare-Object cmdlet will first find items that are diffe
