powershell v2 - how to get process ID - process

Question

I have an Application, that runs multiple instances of itself. e.g
AppName.exe instance1
AppName.exe instance2
AppName.exe instance3
Using Powershell v2 I am trying to create a simple script that given an array of AppNames and instances, it loops through them, checks if they are running, and then shuts them down.
I figured the best way to do this would be check for each instance, if found capture it's processID, and pass that to the stop-process cmdlet.
BUT, I can't figure out how to get the process id.
So far I have:
$appName = "AppName.exe"
$instance = "instance1"
$filter = "name like '%"+$appName+"%'"
$result = Get-WmiObject win32_process -Filter $filter
foreach($process in $result )
{
$desc = $process.Description
$commArr = $process.CommandLine -split"( )"
$inst = $commArr[2]
$procID = "GET PROCESS ID HERE"
if($inst -eq $instance)
{
Stop-Process $procID
}
}
Can anyone tell me where to get the process ID from please?

Answer 1

you can use the get-process cmdlet instead of using wmi :
$procid=get-process appname |select -expand id

Answer 2

$procid=(get-process appname).id

Answer 3

When using Get-WmiObject win32_process ..., the objects returned have an attribute named ProcessId.
So, in the question, where you have:
$procID = "GET PROCESS ID HERE"
use:
$procID = $process.ProcessId
You could also use that in the $filter assignment, e.g.
$filter = "ProcessId=1234"
