How to handle a CTRL-C input from the console as an event like a SIGINT in other languages?
I have to stop a long running script by an external event like entering CTRL-C at the console and then to process some cleanup actions before exiting. I have tried this but it terminates silently aft...
JoergDebus I used this in one of my scripts. This is for using Escape to stop.
while ( $true ) {
if ($host.ui.RawUi.KeyAvailable) {
$key = $host.ui.RawUI.ReadKey("NoEcho,IncludeKeyUp,IncludeKeyDown")
if ($key.VirtualKeyCode -eq 27 ) {
Write-Host ("Stopped") -ForegroundColor Green
return
}
}
}

- Hi Harm.
thanx for your tip.
Catching a key is a good approach. My problem is, that I have long running functions which should be interrupted. Polling during an outer loop like you scribbled it, does not handle this.
Best regards
