PowerShell jobs

 PowerShell jobs 

PowerShell jobs allow you to run long-running or resource-intensive tasks in the background, without blocking the main thread of your script or session. Jobs can be created using the Start-Job cmdlet, and their status and results can be monitored using the Get-Job cmdlet. Here's an example:

# Start a new job to run a script block

$job = Start-Job -ScriptBlock {

    param(

        [int]$Count

    )

    1..$Count | ForEach-Object {

        Write-Host "Processing item $_..."

        Start-Sleep -Seconds 1

    }

} -ArgumentList 5

# Wait for the job to complete and get its results

$job | Wait-Job | Receive-Job

In this example, we create a new job using the Start-Job cmdlet, passing in a script block that will generate some output over a few seconds. We use the -ArgumentList parameter to pass in a value of 5, indicating that the script block should generate output for 5 iterations. We then use the Wait-Job cmdlet to wait for the job to complete, and the Receive-Job cmdlet to get its results (which in this case will be the output generated by the script block).
