Powershell, condition help - taking action only if criteria met

Last Modified: 2020-03-01
Hi Experts,

I have two script below, one is a wrapper script calling or passing arguments to the other.

I'm looking to have this only send the email or take action if the criteria is met that I have in the command line arguments ( Get-CMClientExecutionHistory-Worker -Computername $Computer | Where-Object SuccessOrFailureCode -ne 0 ) for the computers in the list.

Right now this sends to every computer in the list I have, if the command line criteria isn't met, it's blank output.

I'm stuck on how to go about setting this up, any help is appreciated.

# Get-CimClientExecutionHistory-Worker.ps1
    [string[]]$ComputerName = $env:COMPUTERNAME


$Code = {
    # Get Execution History from registry, and package details from WMI
    $ExecutionHistoryKey = "HKLM:\SOFTWARE\Microsoft\SMS\Mobile Client\Software Distribution\Execution History" 
    $ContextKeys = Get-ChildItem $ExecutionHistoryKey | Select -ExpandProperty PSChildName
    foreach ($ContextKey in $ContextKeys)
        If ($ContextKey -eq "System")
            $ContextKey = "Machine"
            $ContextKey = $ContextKey.Replace('-','_')
        [array]$SoftwareDistribution += Get-CimInstance -Namespace ROOT\ccm\Policy\$ContextKey -ClassName CCM_SoftwareDistribution

    # Create a datatable to hold the results
    $DataTable = New-Object System.Data.DataTable

    foreach ($ContextKey in $ContextKeys)
        If ($ContextKey -ne "System")
            # Get user context if applicable
            $SID = New-Object Security.Principal.SecurityIdentifier -ArgumentList $ContextKey
            $Context = $SID.Translate([System.Security.Principal.NTAccount])
            $Context = "Machine"
        $SubKeys = Get-ChildItem "$ExecutionHistoryKey\$ContextKey" 
        Foreach ($SubKey in $SubKeys)
            $Items = Get-ChildItem $SubKey.PSPath
            Foreach ($Item in $Items)
                $PackageInfo = $SoftwareDistribution | Where {$_.PKG_PackageID -eq $SubKey.PSChildName -and $_.PRG_ProgramName -eq $Item.GetValue("_ProgramID")} | Select -First 1
                If ($PackageInfo)
                    $PackageName = $PackageInfo.PKG_Name
                    $DeploymentStatus = "Active"
                    $PackageName = "-Unknown-"
                    $DeploymentStatus = "No longer targeted"

    $DataTable.DefaultView.Sort = "RunStartTime DESC"
    $DataTable = $DataTable.DefaultView.ToTable()
    Return $DataTable


foreach ($Computer in $ComputerName)
    If ($Computer -eq $env:COMPUTERNAME)
        $Result = Invoke-Command -ScriptBlock $Code
        $Result = Invoke-Command -ComputerName $Computer -HideComputerName -ScriptBlock $Code -ErrorAction Continue
    $Result | Select ComputerName,PackageName,PackageID,ProgramName,DeploymentStatus,Context,State,RunStartTime,SuccessOrFailureCode,SuccessOrFailureReason
