In this tutorial, we will learn about the various runlevels that exist within a Linux system.
There are times when a Linux system boots either into a Graphical User Interface (GUI) or a command line. A Linux system may also boot as a single-user system, which means that it is available only to a single user, the superuser used for system maintenance.
The way the Linux system boots and operates is known as the system’s state, known as the runlevel.
