Explain the runs levels and how to alter them?

In Linux, a run level is a stage of initialization that effectively defines what types of system services are functioning. They are generally defined by numbers. In general, there are a total of 7 run levels in the Linux system, and they serve a different purpose. They are:

* Halt system (Sued to turn off the system)
* Basis multi-user mode but there will be no NFS
* Single users mode
* Full multi-user mode (based on the text)
* Multi-user mode (graphical UI)
* Unused
* Reboot system

Now talking about the process for changing the level, one needs to change the file – /etc/inittab. Alter the initdefault entry (id:5: initdefault:). If the users want to alter the run level on the fly, they can do it through the ‘init’ command. Let’s take an example.

When a user types Init 3 in the command line, this will shift the system to run level 3 from run level. To list the current level, the users can use the command “Who -r.”
