How to pass values to nested ForEach?

Question

I am trying to use a variable created in an outer ForEach loop inside an inner ForEach loop. The value does not pass thru as I expect and is always null.

Notice The value for $server is always null can you tell me why and how to fix?

$Srvrs = "SVR1";
$Srvrs | ForEach-Object {


    $server = $_;
    Write-Host "Server value in outer Foreach:" $server;

    $sourceFilesLoc = "D:\Test\SetupSoftwareAndFiles"
    $sourceFiles = Get-ChildItem -LiteralPath $sourceFilesLoc;

    $sourceFiles | ForEach-Object  {
        Start-Job -InputObject $server -ScriptBlock     {
            Write-Host "Server value in inner Foreach:" $server;
            }
        }
}

Answer 1

Pass in the parameters via the -ArgumentList parameter e.g.:

Start-Job -InputObject $server -ScriptBlock {param($svr)
    Write-Host "Server value in inner Foreach:" $svr;
} -ArgumentList $server

Here's a simple example of using -ArgumentList:

PS> $server = 'acme'
PS> $job = Start-Job {param($svr) "server is $svr"} -ArgumentList $server
PS> Receive-Job $job
server is acme

Answer 2

the issue isn't accessing the variable in nested foreaches.. if you did a write-host of the variable inside the inner foreach it would be fine. Its a matter of passing the variable to the job. Jobs are different processes that run in the background.
