Looks like a Windows system... maybe this works:

   out = `dir`

If your computer doesn't have an ls command, you can do the same thing from
Ruby with Dir.pwd

No, you have two other problems:

1) cargo-culting example code for a different platform without
     understanding what it's doing.

2) running a system command from ruby without running that
     command from a shell to confirm that it works as expected.

Both should be pretty easy to fix :slight_smile:

I guess you rather mean Dir.entries('.') or Dir["*"].
