The icacls syntax is actually pretty straightforward and relatively easy to learn. Basically, you use the command, then add the file or folder you want to check or manipulate, and then the permission(s) you want to add/change/delete.

Well, as you can see from my example above and screenshot, you certainly can use PowerShell to use the icacls command. You only need to be aware of some environment variables that need to be referenced a little differently.
