Redirecting stderr problem

Redirecting stderr problem
Code:
% ls -ld /usr /foo ls: /foo: No such file or directory drwxr-xr-x 14 root wheel 512 May 18 02:49 /usr % ls -ld /usr /foo 1>/dev/null/ /dev/null/: Not a directory. % ls -ld /usr /foo 2>/dev/null/ /dev/null/: Not a directory.
^^Why why why doesn't this work for me. Furthermore, where is stdout on the last?
I'm trying to prevent 'find' from barfing the permission denied errors if anybody has experienced that. Wondering if I'm doing something wrong or how to further examine stderr's config on the server.
Side note: Please forgive if this answer is already posted as I've tried searching here and google with no luck. Thanks in advance for your 0.
