A while ago I was trying to copy a bunch of files and couldn't believe the powershell abominations I found: https://techblog.dorogin.com/powershell-how-to-recursively-copy-a-folder-structure-excluding-some-child-folders-and-files-a1de7e70f1b?gi=be511f23383a https://techblog.dorogin.com/powershell-how-to-recursively-c... $exclude = @("main.js") $excludeMatch = @("app") Get-ChildItem -Path $from -Recurse -Exclude $exclude | where { $excludeMatch -eq $null -or $_.FullName.Replace($from, "") -notmatch $excludeMatch } | Copy-Item -Destination { if ($_.PSIsContainer) { Join-Path $to $_.Parent.FullName.Substring($from.length) } else { Join-Path $to $_.FullName.Substring($from.length) } } -Force -Exclude $exclude All to do: find sourceFolder \! -path */app/* | xargs cp -t destFolder Screwed up the formatting a bit in the first example. I'm not positive the second works perfectly but I know which one I'd rather debug.

rsync -a --exclude=app/ --exclude=main.js sourceFolder/ destFolder/ Thank you, thank you unix tools.

First of all, the two examples you present do not do the same thing. The Powershell version preserves paths and excludes more patterns than your find | xargs example. The right way to do this is to just use robocopy. This example has targeted a very specific deficiency in the way Copy-Item works. I could similarly point out that the following Powershell command would be much more difficult in standard unix tooling: Get-WMIObject -Computer $remote -Class Win32_Product | Where-Object { $_.name -like "7-Zip*" } | select Version Which gets the version(s) of 7-Zip installed on a remote machine.
