Exercise 1 - Manage File and Directory Permissions

When a user logs in a Linux system, a new shell process starts, which runs with the user’s user and group IDs. Each user account has permissions that can access only certain files and the files the user creates. The user cannot access files that either belongs to other users or they are system files. The applications that a user starts, it inherits the user id and therefore, has access only to the files and objects on which the user has access. Any object on which the user does not have access, the application, which the user is running, does not have access.

In this exercise, you will manage file and directory permissions.
