    I am trying to learn about WorkFlows in PowerShell.   I found this code doing a Google search and it works.

    workflow CommvaultReport {
    sequence {
    $server_list = @(get-content C:\temp\machines.txt)
    $results = @()
    ForEach -Parallel ($serverName in $server_list) {
    inlinescript {
    $NewObject01 = new-object PSObject
    $NewObject01 | add-member -membertype NoteProperty -name "Server Name" -Value $using:serverName
    $NewObject01
    }
    }
    }
    }


    CommvaultReport | Export-Csv c:\temp\BackUpReport.csv

    ###############################################################################################



    What I am struggling with is gathering more data and writing it to my file.  


    workflow CommvaultReport {
    sequence {
    $server_list = @(get-content C:\temp\machines.txt)
    $results = @()
               ForEach -Parallel ($serverName in $server_list) {
       inlinescript {
                    $ComputerInfo = Get-WMIObject -class Win32_ComputerSystem -computername $server_list -Property *
                    $computerName = $ComputerInfo.name
                    $computerModel = $ComputerInfo.Model
    }
    }
    }
    }

    CommvaultReport $results | Export-Csv c:\temp\BackUpReport.csv

    This does not work and so far nothing has worked.  How do I get $RESULTS piped to my file and have it show me the data for each machine in machines.txt ?

    And to really use workflow technology we would do this which runs the list in parallel by default.

    workflow Get-Report {
	Get-WMIObject Win32_ComputerSystem -pscomputername $PsComputerName
}
$server_list = get-content C:\temp\1.txt
Get-Report -PSComputerName $server_list| Select-Object Name, Model

    I am close but I still don't get the data I am seeking.

                                    


    cls

    workflow Get-Report {
    sequence {
    $server_list = @(get-content C:\temp\1.txt)
    $results = @()
       ForEach -Parallel ($serverName in $server_list) {
           inlinescript {
                        $ComputerInfo = Get-WMIObject -class Win32_ComputerSystem -computername $ServerName -Property *  
                        $computerName = $ComputerInfo.name
                        $computerModel = $ComputerInfo.Model

                        [PSCustomObject]@{
                        PCName=$computerName
                        'Model'=$computerModel  

                   }  # closes the ps custom opject

    }  # Closes the InlineScript

    } # closes the foreach loop

    } # closes the sequence loop

    } # closes the workflow

    $results

    $results | Get-Report | Export-Csv c:\temp\BackUpReport.csv -NoTypeInformation

    $results has no data.   I have 3 machines in 1.txt but it does not seem to find them.

    Rather than trying to guess at how to use PowerShell you need to spend the time learning PowerShell basics.

    Also use the code posting tool:

    workflow Get-Report {
	$server_list = get-content C:\temp\1.txt
	ForEach -Parallel ($serverName in $server_list) {
		inlinescript {
			Get-WMIObject Win32_ComputerSystem -computername $using:ServerName			
		}
	}
}

Get-Report | Select Name, Model

    This is really all you need:

    workflow Get-Report {
	$server_list = get-content C:\temp\1.txt
	ForEach -Parallel ($server in $server_list) {
		Get-WMIObject Win32_ComputerSystem -pscomputername $server
	}
}

Get-Report | Select-Object Name, Model
