Handle errors in ScriptBlock in Invoke-Command Cmdlet

Question

I am trying to install a service on a remote machine using the powershell.

So far I have the following:

Invoke-Command -ComputerName  $remoteComputer         


        

Answer 1

This is almost certainly not the "correct" answer, but this is what I use when I want Invoke-Command to throw an error in the script.

$error.Clear()
Invoke-Command -ComputerName localhost -ScriptBlock {Command-ThatFails}
$if ($error.Count -gt 0) { throw $error[0] }

If you wanted to keep the error in a variable, you could do the following:

$error.Clear()
Invoke-Command -ComputerName localhost -ScriptBlock {Command-ThatFails}
$if ($error.Count -gt 0) { $myErrorVariable = $error[0] }
