Hope this tells you something.
You needed to type a space after 512 before dragging the file into the Terminal window.
That's one tell.
The second is: you need to use an
l (letter ell), instead of a
1 (number one).
l is for length (and we can also use "
-len") .
[it's just the same command as before, with a 512 instead of a 128.]
