Superuser/Root In Linux - What Is It?

Each time you try to make any critical system changes through the command line or GUI, you will be prompted for a password. You can log in as root(alternatively called superuser) to avoid this.

The superuser, also known as root, is the top level user - allowing administrator use to edit/change/install programs. It is not recommend you login as root user, as you can wipe the HDD.

But, if you really must use root user, here is how to login to it.

First you need to define a password. To do that, type the following:

sudo passwd root

You will be prompted to enter a password, and repeat for confirmation.

To login as root

In shell (the command line), type in the following:

su

You will be asked for the root password, type in the root password that you defined earlier and you will be logged in as the superuser.
