Compare two processes using PowerShell

Let’s unravel the intricacies of using Windows PowerShell to uncover the nuances between two instances of the same process running on your system. This illuminating technique involves the adept utilization of the Compare-Object cmdlet, revealing insights that might otherwise remain hidden.

Imagine you’re on a quest to scrutinize and distinguish between two instances of a process, like Chrome. The Compare-Object cmdlet is your guiding compass, allowing you to navigate through the properties that define these processes.

Consider the task at hand: to discern the differences between two instances of Chrome, each characterized by its CPU usage, working set (ws), virtual memory (vm), and identification (id). This is where the Compare-Object cmdlet takes center stage, and here’s how it works:

# Define the two instances of Chrome
$a = Get-Process -Id 18876
$b = Get-Process -Id 19524

# Compare the properties of the instances
Compare-Object -ReferenceObject $a -DifferenceObject $b -Property cpu, ws, vm, id

In this script, `$a` and `$b` represent the two distinct instances of Chrome, each with its unique set of properties. The Compare-Object cmdlet enters the scene as the observer, comparing these instances based on the specified properties: cpu, ws, vm, and id.

Delve into this further: the cmdlet essentially acts as a magnifying glass, highlighting the distinctions that set these processes apart. It points out which process has a higher CPU usage, distinct working set, unique virtual memory, and varying identification number. It’s as if the cmdlet becomes a storyteller, narrating the subtle differences that make each instance of Notepad its own tale.

In essence, this PowerShell technique empowers you to examine, analyze, and uncover the variances between two seemingly identical processes. It’s akin to peering through a microscope, revealing the intricate details that contribute to the larger narrative of your system’s performance. So there you have it – a potent and enlightening method to unravel the disparities between parallel instances of a process, all thanks to the prowess of Windows PowerShell and the Compare-Object cmdlet.
