How would One allow users to "Pause the current Pipeline and return to the command prompt" and later resume in a powershell script?
I stumbled upon this line in a blog post about User Interaction in Powershell
$suspend = New-Object System.Management.Automation.Host.ChoiceDescription "&Suspend", "Pause the current pipeline and return to the command prompt. Type ""exit"" to resume the pipeline."
It was a mock option in a prompt imitating the appearance of a native command (Remove-Item). Lo and behold: That command actually Implements that behavior. Doing a quick Google Search, I did not find anyone trying to implement this in a script.
>Solution :
You can use $Host.EnterNestedPrompt() to suspend the current operation to enter a "nested" prompt – execution will resume once you exit it (using either exit or $Host.ExitNestedPrompt()):
function f {
param([switch]$Intervene)
$abc = 123
if($Intervene.IsPresent){
$host.EnterNestedPrompt()
}
Write-Host "`$abc has value '$abc'"
}
Now try invoking the function with and without the -Intervene switch:
