PowerShell Progress Monitoring

Question

Is there a way for PowerShell to report progress or fire events before it completes? I just started playing with background tasks in PowerShell, and I wonder how far I can advance this feature.

Answer 1

The standard “manual” method is to use the Get-Job cmdlet. As for events, when you create a job using Start-Job, the returned Job object has a "StateChanged" event that you can subscribe to, for example:

$job = Start-Job { Get-Process; Start-Sleep -seconds 60 } Register-ObjectEvent $job -EventName StateChanged ` -SourceIdentifier JobStateChanged ` -Action { Write-Host "Job $($Sender.Id) $($Sender.JobStateInfo)" } 

Answer 2

You can also create your own events from a local or remote task and act on them in a local session.
