Root User in Ubuntu -steps

Before starting with how to become a root user in order to perform sensitive Ubuntu operations, it is important to have some understanding of the significance of a root user in Linux. The latest versions of Ubuntu, by default, do not come with a root user with a specially encrypted password; it has hence created a functionality by the name of “sudo” which you can use to perform various administrative operations. You can either temporarily become root user or you need to provide a password with the sudo command that helps in keeping accountability for all actions of the user as an administrator. By default, the first user created when you install Ubuntu is given the sudo rights. Ubuntu gives it complete root privileges and it is added to the list of sudoers in the /etc/sudoers file.
