Join Don Jones for an in-depth discussion in this video Use Compare-Object for change control, part of PowerShell 3.0 for Administrators.
- Let's look at a practical example of why…you might want to export something to…let's say, XML and then reimport it.…Let's start with a list of processes…that are running on this computer.…Get process.…And we will export that to a CLIXML file…and I'll call it PROCS dot XML.…Now this is a snapshot of the processes…that are running on this computer…at that exact moment.…Now, let's start up a few extra processes.…
Notepad.…Get a copy of calc running maybe.…Maybe, here's an oldie, but goodie.…Now a lot of machines in your environment…especially servers will have a known list of processes.…They should only be doing certain things all the time.…And any additional processes…that get brought into play…kinda represent a change control point.…You need to document that…or at least investigate why that process is running.…So here's what we're going to do.…
I'm going to ask PowerShell to compare…two sets of objects.…My reference set is going to be that stuff…that I saved off to disk just a second ago,…PROCS dot XML.…That's my base line.…
