Hi i can't allow others users to use 777 permission commands . chmod 777 fdisk su normaluser fdisk-l fdisk:you must be root to do that but i think that i don't have to use suders file while I've already changed the command permission to allow the others to use it. but i can use ls command although it has less permission 755 i thought that changing the permission of any executable to rwx for the others will allow any one to execute that executable . is it something related to SElinux . also what is the interpretation of r for the executable ? what if the permission of the executable was only --x--x--x ,will that make a difference ?
Some applications (like fdisk) check internally if they are run by the right user, so although the permissions are 777, they can be run by only one user.
