Patrick Grueanuer waits for a job:
The cmdlet Wait-Job waits until one or all of the PowerShell jobs running in the session are in a terminating state. In this blog post I will show you an example you can build on. Let’s get started.
Start-Job creates one or more PowerShell background jobs. These jobs are running hidden in the background and enable you to continue your work in PowerShell. This example starts a port scan background job.
