PowerShell - Get parent levels for Enumeration

Matt_Howard1

I put together this recursive function today to help me decode and rename our lists. Maybe it can help someone else. The problem I have is that our lists were mostly populated in console, so they have the default Enum.xxxxxxx names, but no indication of where it is used. Using this function will show each enumeration above the one listed, up to and including the root enumeration.

***Assumes you have SMLets :)***

 function Get-SCSMEnumerationParentTree {
    [CmdletBinding()]
    PARAM (
        [Parameter(Mandatory = $true, ParameterSetName = 'Name')]
        [string]$Name,
        [Parameter(Mandatory = $true, ParameterSetName = 'Id')]
        [string]$Id
    )

    switch ($PSCmdlet.ParameterSetName) {
        'Name' {
            Get-SCSMEnumeration -Name $Name | Tee-Object -Variable Enum
            break
        }
        'Id' {
            Get-SCSMEnumeration -Id $Id | Tee-Object -Variable Enum
            break
        }
        default {
            break
        }
    }

    if ($Enum.Parent -ne $null) {
        Get-SCSMEnumerationParentTree -Id $Enum.Parent.Id
    }
}

Output:

C:\Temp\SCSM> Get-SCSMEnumerationParentTree -Name Enum.023d427051dd4ed5aa3685d5329b358a

At the very least, there needs to be some acknowledgement here for the use of Tee-Object 👍️

Wow, all of the acknowledgement. I'm going to go write something with Tee-Object
