An executable file has permissions -rwxrwxr-x and owner is root. When a non-root user tries to execute the file, I get a permission denied error. What am I not understanding?

Where is the location of the file? Is the file in a readable directory?
EDIT: As well what does the file do? Inside does it execute something else that could have a permission issue?

Check the filesystem isn't mounted with the noexec option, which will override the permissions on the file. Can root execute the file?

It's in the home directory and root can execute it just fine. EDIT: It's located under
/opt/my bad– gAMBOOKaCommented Feb 21, 2010 at 22:47
In order to execute you must also be able to read (except for root, who can do anything on plain unix systems)

yeah right i overlooked that - i really thought only root had 'r'– fenCommented Feb 21, 2010 at 22:56
If it is a script (i.e. uses #! on the first line to tell the OS how to run it) check the permissions of the interpreter named there.
