Hi, guys. So now let's proceed. And
in this and next few lectures, I'll
explain you how to perform user
management in Linux systems. And
I'll explain you how to create new
users, how to login under new users,
and how to create files as new
users. Also, I'll explain you how
to change permissions and ownership
of the files. But first of all, let
me answer the question, why users
are actually needed in Linux
systems? You already know that
there is a so called a root user.
And as the root user, you are able
to perform some management tasks
and launch different scripts. And
usually, regular users aren't able
to do so. And in this Linux
container, I am logged in currently
as root user, and if I enter 'whoami',
I will see this information
here. And default home
directory for this 'root' user is
'/root'. And if I enter 'pwd', I
see that I'm inside of the root
folder, and this folder is home
directory for this 'root' user. And
here you see this tilde(~) sign that
actually represents home directory
for a specific user. Also, I have
shown you in this virtual machine
that I was working here in this
terminal and in this graphical user
interface as regular 'bogdan'
user. And if I enter 'whoami' here,
I see 'bogdan'. And if I 'cd'
to home directory, 'cd~', and
enter 'pwd', I will see that the home
directory for this regular user is
'/home/bogdan'. Alright,
that's quick introduction. And now
let's move on and let's create a
new user here in this Docker
container. I will see you guys in
the next lecture. Bye-Bye.
