Check if service is running after using start-sleep - powershell

Question

How do I check if service is running again after Start-Sleep -m 120?
Maybe there is a situation when even after 120 minutes wuauserv can be running.
$getservice = Get-Service -Name wuauserv
If($getservice.Status -eq 'Running')
{
Start-Sleep -m 120
Get-ChildItem -Path $env:SystemRoot\SoftwareDistribution\Download -Force -Recurse | Remove-Item -Force -Recurse -ErrorAction SilentlyContinue
}
Else
{
Get-ChildItem -Path $env:SystemRoot\SoftwareDistribution\Download -Force -Recurse | Remove-Item -Force -Recurse -ErrorAction SilentlyContinue
}

Answer 1

It seems that you only want to call Get-ChildItem once your service is stopped.
One option is:
$getservice = Get-Service -Name wuauserv
$getservice.WaitForStatus('Stopped')
Get-ChildItem -Path $env:SystemRoot\SoftwareDistribution\Download -Force -Recurse |
Remove-Item -Force -Recurse -ErrorAction SilentlyContinue
You can optionally specify a timeout:
$getservice.WaitForStatus('Stopped', '02:00:00')
Note that the WaitForStatus method waits approximately 250 milliseconds between each status check. If that's too heavy, you can use a while loop.
$getservice = Get-Service wuauserv
while($getservice.State -ne 'Stopped')
{
Start-Sleep -m 10
$getservice = Get-Service wuauserv
}
Get-ChildItem -Path $env:SystemRoot\SoftwareDistribution\Download -Force -Recurse |
Remove-Item -Force -Recurse -ErrorAction SilentlyContinue

You can run a script until the service is stopped and then run Get-ChilItem:
while($true){
if(-not isWuauservRunning){
Get-ChildItem -Path $env:SystemRoot\SoftwareDistribution\Download -Force -Recurse | Remove-Item -Force -Recurse -ErrorAction SilentlyContinue
break
}
}
If this is part of a larger script, you can us Start-Job to run this activity on the background because of the use while($true).
You can also do it like that (I don't like this method, I think it better to check the case when the service is stopped):
function isWuauservRunning(){
$isRunning = $false
$service = Get-Service -Name wuauserv
if(($service -ne $null) -and ($service.Status -eq 'Running')){
$isRunning = $true
}
return $isRunning
}
function getAndRemoveItems(){
Get-ChildItem -Path $env:SystemRoot\SoftwareDistribution\Download -Force -Recurse | Remove-Item -Force -Recurse -ErrorAction SilentlyContinue
}
if(isWuauservRunning()){
Start-Sleep -m 120
if(-not isWuauservRunning()){
getAndRemoveItems
}
}else{
getAndRemoveItems
}

$getservice = Get-Service -Name wuauserv
while($getservice.Status -eq 'Running')
{
Start-Sleep -s 1800
$getservice = Get-Service -Name wuauserv
}
Get-ChildItem -Path $env:SystemRoot\SoftwareDistribution\Download -Force -Recurse | Remove-Item -Force -Recurse -ErrorAction SilentlyContinue
