Linux Command Line Tutorial For Beginners 1 - Introduction Video Lecture | Complete Linux Course: Become a Linux Professional - Software Development

hey guys welcome to the first video on
linux command line tutorial for
beginners now the first question you may
ask yourself is why bother about
learning the command line so the simple
answer for this question is graphical
user interface or GUI interface like
this one is helpful in many tasks but
they are not good for all tasks and
gradually when you learn command line
you will observe that you are able to do
your day-to-day tasks or any tasks
related to some programming much faster
than you can do with your graphical user
interface now the graphical user
interface are user friendly you know at
the first look but when you want to do
more about a program for example knowing
the details about what's happening in
the background then you may want to use
command line because by using command
line you know all the background details
of a program right now before diving
into the world of linux command line you
need to learn two terms one is the shell
and second is the terminal now what is
the shell simply put the shell is a
program that takes command from the
keyboard and gives them to the operating
system to perform right now a
command-line or shell you can also say
it's a CLI CLI stand for a command-line
interface now the second term is the
terminal a terminal is a tool which you
can use to pass your shell commands this
is a program that opens a window and
lets you interact with the shell now
there are different operating system
available for the Linux but I will be
using Ubuntu operating system now if you
don't know how you can install Ubuntu on
a VirtualBox or VMware Player I have the
video on that
and you can you know wash them and
install Ubuntu on your native Windows
operating system also using VMware
Player or VirtualBox which are a virtual
machine on which you can host your Linux
operating system so I will be using the
Ubuntu operating system but you are free
to use any other Linux operating system
and terminal commands are all same or
almost the same on all you know Linux
based operating system now on Ubuntu how
you can open our 10 terminal it's really
easy so you just need to go to this
button and then just click it and then
search for terminal so just write
terminal and the first icon you will
find here is your terminals when you
click it it will open the terminal right
now there is one command to open our
terminal also which is a keyboard
shortcut when you press ctrl alt T it
will also open our terminal ok so this
is the shortcut for opening the terminal
now once you are in the terminal then
you can perform bunch of command but
before this we need to understand what
is a filesystem and how you know these
filesystem work in Linux right so like
all other operating system the files on
Linux system are also arranged in what
we called a hierarchical directory
structure which means that they are
organized in a tree-like pattern of
directories in Windows you are no
directories as folders also now
directories may contain files or other
directories also now the most you know
root or basic directory in Linux is the
root directory and under this directory
all files and folders are residing now I
will use this graphical interface to
show you this filesystem of Linux so I
will just go here which is files and I
will open this and then I will go to
this computer so just click this option
which says computer and this is your
root folder ok and root folder start
from this forward slash you can see here
ok and then all the directories reside
in this root folder for example home Lib
or a bin which contains all the binary
you know binaries of your Linux
operating system and other folders which
we learn later right so every Linux
operating system has this root folder
and under which all the files are aside
ok now let's start our Linux command
line journey now the first command you
may want to learn is the PWD command
which is a present working directory
command and this shows you in which
directory you are currently in so let's
give the PWD command so just give PWD
and press Enter and it says home slash
programming knowledge which is my user
name for this computer ok so whenever
you will open a terminal by default the
per present working directory is your
home directory which is home slash your
user name in my case its programming
knowledge right now if you want to go to
the root folder what you need to do so
if you want to go to the root folder
there is a command called CD which is a
change directory command we will learn
this change directory command in details
in the later video but I will just show
you how it works so just give CD and
then give forward slash here which is
our root directory ok so just press
enter and then we will be in the root
directory so once again when you press a
PWD command and press Enter
then you can see we are now in the root
directory the other command is LS which
is list this command also we are going
to learn in detail in the next videos
but let's see how it was so LS is to
list all the files and directories in
the present working directory so just
give LS and press ENTER and it will show
you the same directories and files which
you can see here so I will just make it
a little bit smaller so that we can see
so you can see bin dabbe boot et Cie all
the files and folders you will be able
to find here in this user interface as
you can see here also which are listed
by using this LS command ok so I think
that's it for this video in the next
video we will you know start our journey
with Linux command line and we will
learn the basic command and we will
gradually move to the advanced stuff so
I hope you enjoyed this video please
