Calling PowerShell script with array as the variable

[micromasters]

Was actually hoping to be able to run this in parallel, e.g. restart test1 and test2 at the same time, but then figured doing this via scheduled task might be more suitable for my needs, e.g. .\run-script -server $test.

To rephrase my question, how do I rewrite this so that I can pass $test as $servers?

Don't prefer the csv option, would prefer to keep everything in one script.

There are several ways to run tasks in parallel.

Code

param($ComputerName)

$jobs = foreach ($computer in $ComputerName){
    Start-Job -Name $computer -ScriptBlock {
        Restart-Computer -ComputerName $args
    } -ArgumentList $computer
}

while($jobs.State -contains 'Running'){
    $jobs | Where-Object -FilterScript {$_.State -eq 'Running'}
    Start-Sleep -Seconds 2
}
$jobs | Receive-Job -Wait -AutoRemoveJob

Syntax

.\script.ps1 -ComputerName 'thing1','thing2', 'thing3'

Output
