Use passthru to verify that the cmdlet is complete

I am confused how it works -Passthru.

In my opinion, the parameter is -Passthruused to transfer the result of the cmdlet to the pipeline, even the cmdlet itself does not produce any results.

I tried to write this code first: (I'm trying to recycle the IIS application pool without using the cmdlet Restart-WebAppPool)

Stop-WebAppPool  -Name Foo
Start-WebAppPool -Name Foo

As I expected, it takes time to stop the IIS ApplicationPool, and since PowerShell did not wait for the cmdlets to complete, it Stop-WebAppPoolstops the application pool and returns. Since the application pool is not ready to start, Start-WebAppPoolan error is called and thrown.

So, I changed my code to the following:

Stop-WebAppPool  -Name Foo
Start-Sleep -Seconds SomeValueNeedToGetMeasuredAndChanged
Start-WebAppPool -Name Foo

It works, but not very elegant and flexible.

-Passthru , :

Stop-WebAppPool  -Name Foo -Passthru
Start-WebAppPool -Name Foo -Passthru

, .

, :

Stop/Start-WebAppPool , /. -Passthru , - , PowerShell , , /, .

-Passthru, Stop-WebAppPool, ?

? Restart-WebAppPool. Start/Stop, :

$AppPool = 'Foo'
Stop-WebAppPool -Name $AppPool 
while((Get-WebAppPoolState -Name $AppPool).Value -ne 'Stopped'){
    Start-Sleep 1
}
Start-WebAppPool -Name $AppPool
