Can root user run chmod 000 permission shell script?

Hi,

I have a shell script file which is set to access permission 000. When I login as root (sudo su) and try to run this script, I am getting the Permission denied error. I have read somewhere that root admin user can execute any kind of permission script. Then why this behavior? However, I can cd into a permission 000 directory and do ls though. I have Ubuntu 10.04 machine.

Please read my article on file permissions: Unix File Permissions
