I’m in the process of re-organising (again) my script collection and wanted to check what I had in various folders. I needed to check what I had in two versions of the same folder. Back in the day I had a really good DOS based utility that would do this for me – but I can’t find it anymore. So need to compare – we have a compare-object cmdlet. Quick and easy function

function Compare-Folder {
param ( [string]$folder1, [string]$folder2 ) $folder1, $folder2 | foreach {if (-not(Test-Path $_)){Throw "Folder: $_ not found"}} $content1 = Get-ChildItem $folder1 Compare-Object -ReferenceObject $content1 -DifferenceObject $content2 -IncludeEqual } |
Take the folders as parameters – check they exist. Get the contents of each folder. I’m deliberately not doing a –recurse as that gets too complicated for what I need and then use compare-object on the listings. I used –include equal so I could see which files were common. Its not perfect and it only checks names but its simple and does what I need for now
