Tutorial: chmod: Invalid file mode: −R

[ryandesign]

There's a small problem in this tutorial:

https://github.com/davidpersson/media/blob/next/docs/TUTORIAL

The problem is that when it tells you to run "chmod −R", the character before the "R" is not actually a hyphen; it's Unicode symbol U+2212: Minus Sign. When you copy and paste this command to the terminal, you get the unexpected and confusing error "chmod: Invalid file mode: −R" as reported to the CakePHP discussion group here:

http://groups.google.com/group/cake-php/browse_thread/thread/8dbf051df9c820f1

The patch to fix it is attached.
