I would like to list files with setuid and setgid set up. I used the find command, but I got a lot of permission denied error. I tried to redirect the error to the hole it does not work. I used the command string below

find . -type f \( -perm -4000 -o -perm -2000 \) -exec ls {} \; 2>/dev/null

find: paths must precede expression.

How can I redirect the error of my find result to the hole?

Thanks,
