I have a powershell script that starts a job
start-job -scriptblock {
while($true) {
echo "Running"
Start-Sleep 2
}
}
and then it continues executing the rest of the script.
That job, is kind of a monitoring one for the PID of that process.
I would like to synchronously print the PID every n seconds, without having to end the job.
For example, as the rest of the script is being executed, i would like to see output in my console.
Is something like that possible in powershell?
Thanks.

Yes, you can use events:
$job = Start-Job -ScriptBlock {
while($true) {
Register-EngineEvent -SourceIdentifier MyNewMessage -Forward
Start-Sleep -Seconds 3
$null = New-Event -SourceIdentifier MyNewMessage -MessageData "Pingback from job."
}
}
$event = Register-EngineEvent -SourceIdentifier MyNewMessage -Action {
Write-Host $event.MessageData;
}
for($i=0; $i -lt 10; $i++) {
Start-Sleep -Seconds 1
Write-Host "Pingback from main."
}
$job,$event| Stop-Job -PassThru| Remove-Job #stop the job and event listener
