"There are moments in our lives when we find ourselves at cross roads. The choice that we make in those moments can define the rest of our life". At some point you might get fed up with proprietary OS/software and will start thinking about switching to Linux/open source software.

In order to log into a Linux computer you would require a user account. Once you log in to the computer you can access the files and folders available in the computer. In a Linux  system, each user is identified by the kernel with a number called User Identifier or UID. During user creation the system generates a UID and maps it with a username. The /etc/passwd file contains UID to username mapping of all users in the system. In most Linux operating system the value  of UID lies between 0 - 499 for system generated users and  500 - 60000 for new users created. The default UID of root user is 0.
