Hello everyone. Welcome to another video of Section. 1 course,
introduction allowed set up. This is the third video of
the section 1 introduction to Linux is gripping that
you promised. Before we can have an overview to the links comments for
the people Zoo. This is starting is hanging.
So we wonder how the Linux command
structure works, in Linux command line that
we call terminal. So you're
going to be aware of that. That so we called CMD, no
windows just met or want to know that for
your general knowledge, but we're going to use them later. So
remember these names.
Ellen has come online over, Kurt terminal every comment, identifies
it order or process that you want to
execute the unlocked and Microsoft Windows Samuel.
Powershell Linux is case sensitive.
What is that? We're going to take attention to that after
the slide. So it is important to
mention that you should be aware of the uppercase and lowercase word.
For example, in seemly, you can just type
every comment in uppercase or lowercase
is as important. You can do it and it's
He's going to be wrong. But India. No Linux command line. No,
it's not like that case sensitive.
We're going to sit in our examples. Also, most
common. They specify options or arguments in
case, you don't know how to use all them for
your purpose, or you want to know how to find a specific search.
You can always use a shhh after every comment to
provide you a list of common arguments Dash. H
stands for help H Bar L.
So if Dash H is a
work, just dash dash help. So,
in this cool, see an example of the
Ling's comment. The first commonly, we're going to go have
one over. Really need is a LS common, provide
a listing of available file
names in a current directory of the user. So,
let's see the example.
So here we are in our Linux machine. We're
going to type LS, that's gonna show all the
files in our dietary here is okay.
We can see all the files the in the
path that we are in.
But we'll see what happens when we type LS. Dash.
Cash hell.
Oh, let's see. All the
switches with the explanation of them. So if
you ever curious about any
comment on a Linux, just type cash Edge or
watched as help for that comment after that. And you can see
it's working. You fool common description. Let's
see what's happened. If we have it in uppercase.
L as in a capital or it's not working common,
and not found, but it is CMD. Let's
go to our CMD. This open a CME here. For
example, when
we type
Vir that's going to work exactly like LS. But
in the same reform can see all the
files in a directory was have what happens if we
just type your in a capital way. It's
going to work again. So you now know the difference but
let's get back to our the next. You see how
LS command Works. Let's get to our back to our PowerPoints in
the second example.
We have LS Dash, L. Comment. That
is plays a listing of available file.
Include all the details about them and the permission
is about them. So why is it exactly? The see
again? Let's get back to our Linux. Here's on
us again. So, let's time.
First, let's be a little clean and
clear. We're going to type color here,
but we're going to tell you a shortcut later
to help clear your screen and Linux,
but for now just
use a clerical meant to know your Columbia. Interface
what LS
Dash L is happening when you enter
this command. Okay, we have all the details
about every file here.
for example, the lab that takes the
Time that's created the user net credit
and also the permission of it. They were going to go
through it later in further videos. Well,
it's actually not in our courses that's explain
about the Linux stuff. But maybe
I'm going to court over wheel at a permission Linux to
you know, you have a better view of
what you're doing here. But LS Dash L can
show you all the details about
the falls, the next comment in
PowerPoint. If we get back to it, he's
LF. There's a verse that
is a commented, split hidden files in a
directory. So if you want to see all
the files that include a hidden files sometimes,
They got hidden by purpose or just
hit him because of the system files. So let's get to the Linux and
see why.
Okay, I'm just going to type in LS Dash a and
see what's happened. Okay, we have more filed, more
hidden files. So just
a quick tip, if we follow that install, open Dot the
heat on file. So looking here,
if we type LS.
We see all the files, but without any doubt, but
the fans here that haven't done is a hidden file. So
if you ever see a file that story.it see them
file, you can find it with ALS if you
want to see, you should you eat with that LS? Dash
a. So, let's get back to our PowerPoint again.
Well, you are with another comments. Lots
of comments. That's, we
gonna need it. There is a lot of common analytics or
very difficult ones. You need a list.
Many many hours by at least 24 hours
to let all the things all the colors in your Linux, but
I'm just going to teach you some important moments in
case that you don't know it and you need it in
this course the survival skills.
Bubble Linux. We're going to the Ellis. I
was a shell and stylish L that releasing the
permissions of the file is a term directories. The
next one is a CD. It's also
we have it in the CMB to
What is CD do? Let's go to the Linux.
Basilica man is gonna change your diet or E.
We are terminal. So for example,
in the graphical way, you just going to another file to
another file by clicking on it. But in the terminal
isn't like that. What should I do for 12 with another
directory? Okay, fine director
here. We have downloads here. Okay. I want to go
to the downloads folder. What should I do using CD and
type download?
It's great. Now if you see here, we
are in a downloads directory. So how
do I know which territory am I in? We're going to pay attention
in any further comments. Let's get better
notaries and along the comments that you have. Okay.
We have a pwv here that
shorted, the current directory. Let's go to it. First. Let
me type PWD in and links common line.
We can see them don't win that. We are in.
However, if you want to go back into the actual Devil's under
Dean in the root directory, that is
the main directory of every Linux.
We can type CD.
Double dots and gold dots
is 10 for the parent directories. And
no matter in Mario, and one
go to our, you're in, if you type CD double knot, you're
going to bring back your previous or parents
territory that you are in.
Okay, so let's get to the other commands.
We have our M Dash RF here. What is? That is
removing the directories. So you may Wonder, okay.
We now learn how to move between
the directors. What if I want to delete one, you know,
your windows throughout the right? Click on it and delete, but
it's not, you know, Common line in a window in the Linux
in the like that. So let's get to the terminal.
Okay, what file do we have here is check it out. So
I want to delete, I
don't know. You don't recall the music here. Under
stop RN, pressure. RF music.
That's it LS.
There is no music.
There's no music file here anymore. The music
file. Just tilted with this comment.
Okay. Now we learn on the things about
removing moving to other doctor is showing them. What
if I want to copy the files and
easy with the common EP.
Let's see, for
example, we have a folder, text here
and I don't want to copy it.
If you file that txt to
the file or another.
Name under no path. Txt.
Here it is.
It's have been copied to another name.
In the same directory. Also,
you can bring directories.for example,
when you type CP and you want to copy another
follow. To do know if three, we can just do
this file, the text here and learn what
we will download, and put it in the download directories
and call it file to
Dot txt.
And LS from downloads directory.
If we have this file here, and we committed with a CPN, copy
from the phone texting. All right,
then let's get to the another one, the no comment read,
or create a text box file. Let's say
normal file is going to works for you as
a teacher, you know, for example, in notepad in the windows. So
for example, we type in Nano. Also,
we have another call editorial,
Linux. We I, but
that's a little more professional. That I don't want
to get into the hardest of yet. Just going to keep it easy. So,
not only is, the more, is it in a? We, I so
don't know. Add, for example, Court,
read that you stink.
It's gonna open new window that
we can type in it, anything either.
Bye control X and click
on quick and
enter. It's going to save though.
We have a new.
Text file here code red and
we type something in it.
Next comment is if config that
you cite in the previous videos and
it's going to give us their IP addresses of the machine. The
next one is a ping that
you also selects one, in the previous comments. Do
the pink, the host. The last one
is the who is there? We're going to pay attention to do that, further
videos, and then we're going
to work with it.
To get information about our targets. So as I mentioned and
I promised, I want to give you some shortcuts in
a Linux.
As always, there is a minute shortcuts in the OR digital world that
make our life easier and more productive. Links
always has made the same concept. There
is a minute shortcut that you can help you. And
during the process. We are going to show some of them. And
one of the most important things don't waste your time, which
type in clear, comment there's control L and
Screen gonna clear immediately. The
next one is control you as clear. Common line
immediately does not conduct all the screen.
Going to be there comes going to be dirt, but it's gonna
move you to the next page of it. So control element
and removed. All the comments from the screen but
control you are going to the next page and put the comments are
still there. But our run up
down is going to scroll down between the commons histories. So
if you want to comment that you
type it in there, I don't know 10 minutes ago,
can just do it with the screw lock and scroll down under
control a is moved to the beginning
of the
common line and for the editing.
PostScript over your summary. First, we're going
to Quick brief on Alex command structure then in the
Second Step. So important comments, LSP DVD
CD and they moved on files, copy them and
then after all some reporter
short course of a bitter experience in Linux.
The next video is going to be a section 2
and will not start nmap Essentials. Finally,
after section one, we've done with
a Linux and basic things. We're going to move it to the end map and
going to explain all the essential and fundamental
things about end up. Good luck.
