How to capture the Return Value of a ScriptBlock invoked with Powershell's Invoke-Command

Question

My question is very similar to this one, except I\'m trying to capture the return code of a ScriptBlock using Invoke-Command (so I can\'t use the -FilePath option). Here\'s

Answer 1

I have been using another method lately to solve this problem. The various outputs that come from the script running on the remote computer are an array.

$result = Invoke-Command -ComputerName SERVER01 -ScriptBlock {
   ping BADHOSTNAME
   $lastexitcode
}

exit $result | Select-Object -Last 1

The $result variable will contain an array of the ping output message and the $lastexitcode. If the exit code from the remote script is output last then it can be fetched from the complete result without parsing.

To get the rest of the output before the exit code it's just:
$result | Select-Object -First $(result.Count-1)
