PowerShell pause – how can you pause a PowerShell script?

Two ways come to mind.

First if you just want the script to pause for a specified time period then you can use Start-Sleep

1..10 |
foreach {
$PSItem
if ($PSItem -eq 5) {
Write-Warning -Message “Starting sleep”
Start-Sleep -Seconds 5
}
}

Run this and you’ll see the numbers 1-5 output then then warning message. After the delay you’ll see the numbers 6-10 output.

But what if you want to control the pause manually? Not sure if there are advantages to this approach but if you do need to do this you can use Read-Host

1..10 |
foreach {
$PSItem
if ($PSItem -eq 5) {
Read-Host -Prompt “Press Enter key to continue”
}
}

You’ll see the numbers 1-5 output then the message

Press Enter key to continue:

After pressing the enter key the script continues and outputs 6-10

Don’t know why you’d want to do this in an automation scenario but the technique is there if you need it – I don’t recommend the approach.

There are also a few cmdlets that can be used under specific circumstances:

Wait-Event
Wait-Job
Wait-Process
Wait-VM

Also check the –wait parameter on Restart-Computer
