If you want to work with Linux, you need to login. Logging in means that you are
going to use a user account and this user account must have been set up for you.
Current Linux distributions By default, create an administrator user while installing.
There is also the root user, but don't use it.
The root user has unrestricted access to the system, but on most distributions it doesn't even have a password by default.
In the previous lesson you have seen that while installing Centos you can set
the password for the root user. On Ubuntu this option isn't even given.
So login as your normal user with administrator privileges. That will give you enough.
Now login may happen from a console.
A console is a text based interface.
You can also login from a graphical user interface or remotely using Secure Shell.
Now what about graphical versus console? What should you use to work with?
Well, different graphical user interface systems are available, but GNOME is a de facto standard.
GNOME is used on Red Hat as well as on Ubuntu and many other Linux distributions as well.
Now, for all Linux graphical user interfaces, you should know that the graphical user interface
provides limited functionality on servers. You often don't even find a graphical user interface.
That means that you need to focus on learning the command line.
Let me show you what the command line login looks like.
Here you can see command line login.
On the command line login we see short identification of the operating system and
then it's asking how to login. Well, this is where I enter my username
and as well my password. And that brings me to the command line.
On this command line we see the bash shell and you will learn how to work with the bash shell later.
In case you are wondering, do we also have this command line on the graphical user interface?
Of course, it's called the terminal. And the easiest way to access is to type term for terminal
in the search bar on the top of your screen and and then you start your terminal.
So this is a terminal and this is what it's all about.
