I have a Problem with my script, and I can't find the solution. Allways when I try to run this script it says:

Cmdlet Start-Process an der Befehlspipelineposition 1 Geben Sie Werte für die folgenden Parameter an: FilePath:

What does this mean? I know I'm not very good in Powershell, just began to script in last summer. So it may look a bit ugly...

here's my script, hope someone could help me:

function Task_S{

    #starting 'task_s.ps1'
    $thisScriptDirectoryPath = Split-Path -parent 
    $MyInvocation.MyCommand.Definition
    $utilityScriptName = "..\Start_and_furthers\task_s.ps1"
    $utilityScript = (Join-Path $thisScriptDirectoryPath $utilityScriptName)
    $result = .$utilityScript
}

function Task_D{

    #starting 'task_d.ps1
    $thisScriptDirectoryPath = Split-Path -parent 
    $MyInvocation.MyCommand.Definition
    $utilityScriptName = "task_d.ps1"
    $utilityScript = (Join-Path $thisScriptDirectoryPath $utilityScriptName)
    $result = . $utilityScript
}

function Task_I{

    #starting 'task_i.ps1
    $thisScriptDirectoryPath = Split-Path -parent 
    $MyInvocation.MyCommand.Definition
    $utilityScriptName = "task_i.ps1"
    $utilityScript = (Join-Path $thisScriptDirectoryPath $utilityScriptName)
    $result = . $utilityScript

I think I've fond the solution. I just changed the function for the tasks, so it takes the path with PS. So now it looks like this:

$utilityScriptName = "..\start2.ps1"
$utilityScript = (Join-Path $PSCommandpath $utilityScriptName)
$result = .$utilityScript

This works well, but I don't know if this also works for other scripts. Well thanks for your help

You can try this instead?

$ps = new-object System.Diagnostics.Process
$ps.StartInfo.Filename = $utilityScript
$ps.StartInfo.RedirectStandardOutput = $True
$ps.StartInfo.UseShellExecute = $false
$ps.start()
$ps.WaitForExit()
$result = $ps.StandardOutput.ReadToEnd();

I'd recommend you make it into a function though so you can call it multiple times. Like so:

function RunProcessWithOutput($fileName)
{
$ps = new-object System.Diagnostics.Process
$ps.StartInfo.Filename = $fileName
$ps.StartInfo.RedirectStandardOutput = $True
$ps.StartInfo.UseShellExecute = $false
$ps.start()
$ps.WaitForExit()
return $ps.StandardOutput.ReadToEnd();
}

and call like this

$result = RunProcessWithOutput $utilityScript

and this is the result

function RunProcessWithOutput($fileName)
{
$ps = new-object System.Diagnostics.Process
$ps.StartInfo.Filename = $fileName
$ps.StartInfo.RedirectStandardOutput = $True
$ps.StartInfo.UseShellExecute = $false
$ps.start()
$ps.WaitForExit()
return $ps.StandardOutput.ReadToEnd();
}

function Task_S{

    $thisScriptDirectoryPath = Split-Path -parent 
    $MyInvocation.MyCommand.Definition
    $utilityScriptName = "..\Start_and_furthers\task_s.ps1"
    $utilityScript = (Join-Path $thisScriptDirectoryPath $utilityScriptName)
    $result = RunProcessWithOutput $utilityScript
}

function Task_D{

    #starting 'task_d.ps1

    $MyInvocation.MyCommand.Definition
    $utilityScriptName = "task_d.ps1"
    $utilityScript = (Join-Path $thisScriptDirectoryPath $utilityScriptName)
    $result = . $utilityScript
