Using Start-Job on script

Question

Using a script in PowerShell to recursivly pass through all folders on multiple NAS boxes to display every folder with its full path in an Out-File. Using the Get-FolderEntry script I found here.

Since I have multiple NAS boxes with more then 260 chars in the filename/pathlength I figured I'd use multithreading to speed the process up.

Code:

. C:\Users\mdevogea\Downloads\Get-FolderEntry.ps1
# list with the servers
$Computers = Get-Content C:\Users\mdevogea\Desktop\servers.txt

# scriptblock calling on get-FolderEntry
$sb = {
    param ($Computer, $fname)
    C:\Users\mdevogea\Downloads\Get-FolderEntry.ps1 -Path $Computer |
        fl | Out-File -Append -Width 1000 -FilePath $fname
}

foreach($Computer in $Computers)
{
    $name = $Computer.Replace("\", "")
    $fname = $("C:\Users\mdevogea\Desktop\" + $name + ".txt")
    #Get-FolderEntry -Path $Computer | fl | Out-File -Append -Width 1000 $fname

    $res = Start-Job $sb -ArgumentList $Computer, $fname
}

# Wait for all jobs
Get-Job
while(Get-Job -State "Running")
{
    Write-Host "Running..."
    Start-Sleep 2
}
# Get all job results
Get-Job | Receive-Job | Out-GridView

So far:

1. I either get empty files with the correct naming of the file.

2. I get the correct named file with the code of Get-FolderEntry in it.

3. I get errors depend on what I pass along to the scriptblock.

In short, it's probably stupid but don't see it.

Answer 1

Found it eventually myself after some trial and error:

. C:\Users\mdevogea\Downloads\Get-FolderEntry.ps1
# list with the servers
$Computers = Get-Content C:\Users\mdevogea\Desktop\servers.txt

# scriptblock calling on get-FolderEntry
$sb = {
    Param ($Computer, $fname)
    . C:\Users\mdevogea\Downloads\Get-FolderEntry.ps1 
    (Get-FolderEntry -Path $Computer | fl | Out-File -Append -Width 1000 -FilePath $fname)
}

foreach ($Computer in $Computers)
{
    $name = $Computer.Replace("\", "")
    $fname = $("C:\Users\mdevogea\Desktop\" + $name + ".txt")
    $res = Start-Job $sb -ArgumentList $Computer, $fname
}

# Wait for all jobs
Get-Job
while (Get-Job -State "Running")
{
    Write-Host "Running..."
    Start-Sleep 2
}
# Get all job results
Get-Job | Receive-Job | Out-GridView

Thanks a lot Ansgar for pointing my in the right direction!
