Powershell dynamic Start-Job command to execute all powershell scripts in subfolders in parallel

Question

For an important data migration, I would like to execute in parallel multiple scripts in side subfolders :

I did not succeed to do this :

$folders = Get-ChildItem -Directory

foreach($folder in $folders){
    $cmd = "powershell '$folder\script.ps1'"
    $job = start-job -ScriptBlock {Invoke-Expression $cmd}
}

Thank you for your help!

You can use Invoke-Command for concurrent processing. Here's an example that may meet your requirements.

Get-ChildItem -Directory | ForEach-Object {
    $folderPath = $_.FullName
    Start-Job -ScriptBlock { .\script.ps1 $using:folderPath }
}

Get-Job | ForEach-Object {
    $result = Wait-Job $_ | Receive-Job
    Remove-Job $_
    $result
}
