Details:

the command "ls" can find a file that find cannot. I think that find should
either find files of this type by default, or at least have an option to do
so. From what I understand, find cannot find the file because it attempts to
cd into the directory before listing, instead of just listing the directory.
It is possible that you have permission to do one but not the other.

To reproduce the situation, please see the following commands and output:

root@system76-pc:/home/xinwei/bugreport# ls -l
total 4
d---r--r-- 2 root root 4096 2009-07-05 13:27 protected

root@system76-pc:/home/xinwei/bugreport# ls -l protected
total 0
-rw-r--r-- 1 xinwei xinwei 0 2009-07-05 13:27 canttouchthis
root@system76-pc:/home/xinwei/bugreport# exit
xinwei@system76-pc:~/bugreport$ ls -l protected/

ls: cannot access protected/canttouchthis: Permission denied
total 0
-????????? ? ? ? ?                ? canttouchthis
xinwei@system76-pc:~/bugreport$ find ./ -name canttouchthis
xinwei@system76-pc:~/bugreport$ sudo !!

sudo find ./ -name canttouchthis
./protected/canttouchthis
xinwei@system76-pc:~/bugreport$

OpenSolaris find doesn't either:

flare:~/tmp$ find ft/tmp -ls
347455    4 drwxr-xr-x   3 james    1001         4096 Jul  8 09:54 ft/tmp
347457    4 drw-r--r--   2 james    1001         4096 Jul  8 09:54
ft/tmp/nonexecutable
find: cannot read dir ft/tmp/nonexecutable/: Permission denied
flare:~/tmp$ ls -l ft/tmp/nonexecutable
ft/tmp/nonexecutable/foo: Permission denied
total 0
$ find ft -print
ft
ft/tmp
ft/tmp/nonexecutable
find: cannot read dir ft/tmp/nonexecutable/: Permission denied
flare:~/tmp$ uname -a
SunOS flare.spiral-arm.org 5.11 snv_101b i86pc i386 i86xpv
