How do I get the parent id of a process on powershell?

Question

clear
$name = Read-host -Prompt 'Name of service'
$p = Get-process $name

$id = $p.Id
$parentId = $p.Parent.Id
echo $parentId

I've tried this, but it doesn't return anything

Answer 1

Get-Process doesn't contain parent ID, so you need to use Get-CimInstance

clear
$name = Read-host -Prompt 'Name of service'

$ParentProcessIds = Get-CimInstance -Class Win32_Process -Filter "Name = '$name'"
$output = $ParentProcessIds[0].ParentProcessId

Write-Host $output
