Pipe sc query output to powershell method?

Question

I'd like to pipe output from sc query to a method in powershell. For example, checking the status of a service and finding the part that says "STOPPED", and performing an action based on that output.

Is there a way to do this right from the output of sc query? Or do I need to output the results to a text file, and then.. I'm not sure, run a for-loop to find the piece I'm looking for to make an if condition true / false.

This is what I have so far:

Function IsStopped {
    sc.exe query remoteregistry >> RemoteRegistry.txt
    Get-Content -Path C:\RemoteRegistry.txt | Where-Object {$_ -like '*stopped*'} | ForEach-Object {


}

Not sure where to go next?

PowerShell has a cmdlet for examining services. Running Get-Service without parameters gives you all of the running services in the same way sc.exe does (actually while researching this I reminded myself that in PowerShell sc, without .exe, is an alias for Set-Content, so I ended up generating some useless files. This might be another good reason to use Get-Service to avoid confusion with Set-Content).

Running Get-Service | Get-Member gives a list of the properties and methods from the output of the command. Status is the Property of interest, so we run:

Get-Service | Where-Object { $_.Status -eq 'Stopped' }

The output of this command can then be piped into a for each loop as you have suggested, and each service's properties or methods can be accessed using the $_ shorthand:

Get-Service | Where-Object { $_.Status -eq 'Stopped' } | ForEach-Object {
    Write-Host "Do something with $($_.ServiceName)"
}

It is possible to restart services in this manner, using $_.Start(), but I would recommend writing some error handling into the process if that's your ultimate aim.'

If you need more information, such as the executable, you might want to look here:

Thank you! Not sure why I thought remote registry was something only accessible by sc. This works for me though, kudos!
