Exit powershell script when another process ends

Question

I am trying to make a powershell script to exit simultaneously with notepad. The script should do file backups in the background, so it runs with while(1). I subscribe to exited event of notepad process, but exit command doesn't seem to work in Action block. Nothing happens when I close notepad.

$gameRunning = Get-Process notepad -ErrorAction SilentlyContinue

if ($gameRunning) {
Register-ObjectEvent -InputObject ($gameRunning) -EventName exited -Action {exit} -SourceIdentifier NotepadRunning
}
else {
Write-Host "Game not running."
}

while(1)
{}

Any idea how to make it exit from Action scope?

Well, it blocks the process, and I need it to do file backups in the background. — Peter

Then you better to check $gameRunning.HasExited in safe to interrupt points. Otherwise you are risking to interrupt your background backup in undetermined state. — user4003407

Use Environment.Exit():

Register-ObjectEvent $gameRunning -EventName Exited -Action {[Environment]::Exit(0)} -SourceIdentifier NotepadExited
