I will come back here in this Kali Linux.
Uh, let's go first learn something about this Kali Linux.
Okay.
Some command, okay, that we are going to use through the course.
And very common.
These are very common that we are going to use it a lot.
So you need to learn them okay.
First I have to tell you that in Kali Linux we have to kind of user okay.
Right now we have a normal user and we have used super user.
A normal user is only able to read some file, edit some of the file, but not all the files that the
super user is able to edit, delete and do everything with the system.
So right now I am a normal user.
If I want to be a super user in windows we call it administrator.
I use this command okay, sudo is you and then hit enter right here.
Maybe it will ask for a password if it asks.
So you write curly.
Okay.
That is the password for this curly mission right now.
And right now you see that I am root.
That means I am the super user.
Okay.
If I want to exit, I use exit command.
Now, if I use clear, so it will clear the terminal.
So there is another command that we're going to use that is called PWD.
PWD is a command that shows the current directory you will location right now where you located in which
directory.
It will show you that.
So right now you see I am located in home then Cali.
And if I use PWD so it shows me this one.
And there is another command called Ellis.
Ellis stands for for list I think okay.
And if you use it, it will list all the directory that is located where you look at it okay.
So in your location and you can use some other places.
And for example you look at it in home directory and you want to see what is inside the document again,
you can use it very easily like this list form.
And you see we are inside whom we have colleague.
And if I use poly and then for example.
And desktop okay.
And hit enter.
You see we have nothing on desktop right now okay.
So it is how we can use list.
There is another command that is called CD.
CD stands for change directory okay.
For example I'm trying to go to document folder okay.
So I use CD document and hit enter list.
Here is nothing.
You see my location.
It is document.
If I use PWD which is showing my location right now current location it is into document folder if I
go back.
So I use city and then two dot okay.
And now I am back where I was.
There is one another command which is very, very important.
That is called man.
Okay.
This man.
This man command will show you all information about other command that you want.
For example, I want to use, uh, okay, a list that is here I'm going to see all information about
list.
I don't know how to use it for example.
So I use man list and then it will give me information that I.
How can I use you see here we first use list and then add an option here.
And then name of the file or location of the file.
You see we can use a or all it is.
It says do not ignore enter starting with A or B plus size.
See we have if g, g, h see and a lot of thing here we have L here use a long listing format okay.
And okay.
Here is a lot of thing that you can read if you need it okay.
again.
And if you're somewhere okay about some command so you can use it.
So now I hit Q and then it quit that.
So.
It was it okay.
And also another important information is how we can install something like some application into Kali
Linux.
And we can use apt app.
It then install name of the application like Terminator.
Terminator is not an application right now okay.
Now if I hit enter it must install it again.
But right now you see that it is telling me that permission denied.
That is because I'm not the superuser and I am not allowed to install any application to the Linux.
Okay, so I have to be superuser.
How can I be superuser?
So I use sudo and then this command or sudo is you hit enter.
Now I use apt get It install, for example, update or terminator or let's say a apt get update.
I want to update this.
Okay.
So now it will start updating this okay.
So you need to have network connection while you're updating and while you're installing some application
or something in it.
Okay.
So it was how you can use some basic command okay.
And if you're trying to follow the Linux course and it is not going to be a Linux course, okay.
It is a Python course.
So we are going to learn this simple steps simple commands because we need it okay.
And maybe in the future the full package for Linux Kali Linux penetration testing with Linux will come.
I will record it okay.
And if not so it's okay.
Right now it is enough and we will learn a lot of things through the course.
And let's go for the next lecture.
