The permission function is used to calculate what, if any access each class or level of user has to each file on a Unix machine. The permission task is one of the data components stored in the inode table entry for the folder.
Every file has permission or protection attributes for 3 levels or classifications of machine user, i.e.
These permissions are loaded using the ls -l command. The permission mask is spited into three areas, also named levels of permission. The left most group of three functions are those permissions that apply to the operator, or individual who contains the file. In that case, ownership is calculated by the user identification number given when the file is build.
