Getting output from a job

I'm failing miserably to get any output from jobs - what is wrong with the following code?

$test = {
    DIR
}

$mjob = Start-Job -ScriptBlock {$test}
while (Get-Job -State Running){}
Receive-Job -Job $mjob -OutVariable $otest

Write-Host($otest)

You can use the pipeline to wait for the job to finish and then receive its result. Make sure to remove the braces when you pass a scriptblock to the ScriptBlock parameter, otherwise you're creating a nested scriptblock:

$test = { DIR }
Start-Job -ScriptBlock $test | Wait-Job | Receive-Job

When you use -OutVariable supply only the name of the variable e.g.:

... -OutVariable otest

unless $otest happens to contain the name of the variable you want to save the output to.

A few other suggestions. $test represents a scriptblock so you don't need to put {} around it. And rather than wait using a while loop, just use Wait-Job e.g.:

$test = { get-childitem }
$job = Start-Job $test
Wait-Job $job
Receive-Job $job -OutVariable otest

$otest
