• File Get-ChildItemColor.ps1 — part of check-in [d9bc3eb0cd] at 2018-06-10 14:25:46 on branch trunk — A wrapper for Get-ChildItem with color highlighting for different file types. I was thinking of the Linux ‘ls —color’, but didn’t bother to match up colors or anything. TODO: The ability to sort by type would be nice. Note: you will have to remove the documentation at the beginning of the function if you want to use it with versions prior to v2.0 CTP3. (user: tojo2000 size: 2534)
