Hi New to PowerShell, I was wondering when using Invoke-command against a number of machines is there away to return the data back to a variable on the local session? I get when a need to bring a variable from the local machine to the remote session you need to use param with -argumentlist but don’t get it vice versa. Thanks Carl ---

``` $data = Invoke-Command -ComputerName compy -ScriptBlock {Get-ChildItem c:\} ``` Just a simple assignment, excepting that the $data will have extra properties that invoke-command adds in. One of those properties is the computer name, so that is what you can use to filter out the results per the computer that returned them. $data will hold the results of all computers it is ran against. ---

this works local for one machine * * * $Array = @() $Groups = get-pvsauthgroup Foreach ($Group in $Groups.AuthGroupName) { $PVSGroup = get-pvsauthgroup -AuthGroupName $Group | Select-Object AuthGroupName, Description $PVSGroupUsage = Get-PvsAuthGroup -AuthGroupName $Group | Get-PvsAuthGroupUsage | Select-Object Name, Role $PVSSite = Get-PVSSite | Select-Object SiteName $Props = [ordered]@{‘PVS Site’=$PVSSite.SiteName; ‘AuthGroupName’=$PVSGroup.AuthGroupName; ‘Description’=$PVSGroup.Description; ‘Permission’=$PVSGroupUsage.Name; ‘Role’=$PVSGroupUsage.Role } $obj = New-Object -TypeName PSObject -Property $Props $array += $obj } $array * * * this is what I am trying remotely for a few machines $Array = @() Foreach ($PVServer in $PVServers.name) { Invoke-Command -Computername $PVSServer -ScriptBlock { Import-Module ‘C:\Program Files\Citrix\Provisioning Services Console\Citrix.PVS.SnapIn.dll’ $Groups = get-pvsauthgroup Foreach ($Group in $Groups.AuthGroupName) { $PVSGroup = get-pvsauthgroup -AuthGroupName $Group | Select-Object AuthGroupName, Description $PVSGroupUsage = Get-PvsAuthGroup -AuthGroupName $Group | Get-PvsAuthGroupUsage | Select-Object Name, Role $Props = [ordered]@{‘PVS Site’=$PVSSite.SiteName; ‘AuthGroupName’=$PVSGroup.AuthGroupName; ‘Description’=$PVSGroup.Description; ‘Permission’=$PVSGroupUsage.Name; ‘Role’=$PVSGroupUsage.Role } $obj = New-Object -TypeName PSObject -Property $Props $array += $obj }}} ---

``` $Array = Invoke-Command -Computername $PVSServers.name -ScriptBlock { #... New-Object -TypeName PSObject -Property $Props }#... ``` You are not going to be able to reference the memory space on the local computer from the remote, you’ll have to catch the returned values. ---

Its not possible the way you are trying it, because $array is in the memory of the local computer and the remote computer can’t access $array. So, ``` $obj = New-Object #... $array += $obj ``` cannot work. You have to modify the script block to return a value, hence my examples change of not assigning the result of New-Object to $obj and just having New-Object by itself. Then on the local computer side, assigning the results to a variable. My example was something to try with everything I didn’t change commented out so to highlight my suggested changes. ---
