.SYNOPSIS A function to retrieve PowerShell commands from a computer. Defaults to the local machine if -ComputerName is not specified. .DESCRIPTION If you run Get-PSVersionCommand without -Export, you will get all commands from system wide modules returned. With the -Export parameter specified the results will be exported to an XML-file. .PARAMETER ComputerName The name of the computer to retrieve information from. .PARAMETER Path The path to the generated XML-file when -Export is specified. If -Path is not specified to Get-PSVersionCommand -Export, the default naming convention for the generated XML-file is “OS Caption_PSVersion_PSEdition.xml” (for example Microsoft Windows Server 2016 Datacenter Technical Preview 5_5.1.14284.1000_Core.xml). .PARAMETER Export Switch parameter to specify export to an XML-file rather than returning the results .PARAMETER ModuleFilter Wildcard filter to limit the modules to filter on, for example Microsoft.* .EXAMPLE Get-PSVersionCommand -Export .EXAMPLE Get-PSVersionCommand -ComputerName HPV-2016TP5 -Export -Verbose .EXAMPLE Get-PSVersionCommand -ComputerName HPV-2016TP5 -Export -Path "~\Microsoft Windows Server 2016 Datacenter Technical Preview 5_5.1.14284.1000_Core.xml" .INPUTS System.String .OUTPUTS System.String .LINK about_PSVersionCompare #> function Get-PSVersionCommand { [CmdletBinding()] param ( [Parameter(Mandatory=$false)] [string] $ComputerName = $env:computername, [Parameter(Mandatory=$false)] [string] $Path, [Parameter(Mandatory=$false)] [switch] $Export, [Parameter(Mandatory=$false)] [string[]] $ModuleFilter = '*' ) $Session = New-PSSession -ComputerName $ComputerName $PSVersionCommandData = Invoke-Command -Session $Session -ScriptBlock { Get-Module -ListAvailable | Where-Object { ($PSItem.ModuleBase -like "$env:SystemRoot\system32\WindowsPowerShell\v1.0\Modules*" -or $PSItem.ModuleBase -like "$env:ProgramFiles\WindowsPowerShell\Modules*") -and $PSItem.Name -ne 'RemoteDesktop' #workaround for DefaultCommandPrefix issue, implemented only by the RemoteDesktop module.
