.SYNOPSIS A function to compare PowerShell variables between two computers. .DESCRIPTION Compare-PSVersionVariable have two parameter sets which makes it possible to compare based on either XML-files pre-gathered from systems, or data gathered directly via PowerShell remoting. .PARAMETER SourceVersionPath Path to the source XML-file for the comparison .PARAMETER CompareVersionPath Path to the differemce XML-file for the comparison .PARAMETER SourceVersionComputerName Name of the source computer for the comparison .PARAMETER CompareVersionComputerName Name of the difference computer for the comparison .EXAMPLE Compare-PSVersionVariable -SourceVersionComputerName HPV-VM-2016TP4 -CompareVersionComputerName HPV-JR-2016TP5 .EXAMPLE $PSCommandDataRoot = 'C:\Program Files\WindowsPowerShell\Modules\PSVersionCompare\PSCommandData' $SourceVersionPath = Join-Path -Path $PSCommandDataRoot -ChildPath 'Microsoft Windows Server 2016 Datacenter Technical Preview 4_5.0.10586.0_Desktop_Variables.xml' $CompareVersionPath = Join-Path -Path $PSCommandDataRoot -ChildPath 'Microsoft Windows Server 2016 Datacenter Technical Preview 5_5.1.14284.1000_Desktop_Variables.xml' Compare-PSVersionVariable -SourceVersionPath $SourceVersionPath -CompareVersionPath $CompareVersionPath .INPUTS System.String .OUTPUTS System.String .LINK about_PSVersionCompare #> function Compare-PSVersionVariable { [CmdletBinding()] param ( [Parameter(Mandatory=$true,ParameterSetName = 'InputFromXml')] [string] $SourceVersionPath, [Parameter(Mandatory=$true,ParameterSetName = 'InputFromXml')] [string] $CompareVersionPath, [Parameter(Mandatory=$true,ParameterSetName = 'InputFromComputer')] [string] $SourceVersionComputerName, [Parameter(Mandatory=$true,ParameterSetName = 'InputFromComputer')] [string] $CompareVersionComputerName ) switch ($PSCmdlet.ParameterSetName) { 'InputFromXml' { $SourceVersion = Import-CliXml -Path $SourceVersionPath | Sort-Object -Property Name $CompareVersion = Import-CliXml -Path $CompareVersionPath | Sort-Object -Property Name } 'InputFromComputer' { $SourceVersion = Get-PSVersionVariable -ComputerName $SourceVersionComputerName | Sort-Object -Property Name $CompareVersion = Get-PSVersionVariable -ComputerName $CompareVersionComputerName | Sort-Object -Property Name } } Compare-Object -ReferenceObject $SourceVersion -DifferenceObject $CompareVersion -Property Name -IncludeEqual -PassThru } |
