Well, one of the most fundamental tasks in Linux or any operating system is adding and removing software.
You will often need to install software that didn't come with your distribution or remove unwanted software,
so it doesn't take up her hard drive space.
Some software requires other software to run.
Uh, so and you will sometimes find that you can download everything you need at once in a software
package, which is group of files, typically libraries and other dependencies that you need for a piece
of software to run successfully.
When you install the package, I'll um.
Uh, we don't when you install a package here.
All the files fit within it are installed together here, as you can see here, we have so many hacking
tools in Linux like password attacks, violence so that we will.
You will learn all of our tools in our course here.
So, um.
In this lecture, we examine three key methods for adding new software a package manager, uh, graphical
user, interface based installation managers and kit.
So using API to let's start using epithet to handle software.
In Debian based Linux distributions, which includes no Kali and Ubuntu, the default software manager
is an advanced packaging tool, a team whose primary command is apt.
Get here and in the simplest and most common form, you can use APT, get to download and install new
software packages, but you can also update and upgrade and charter it.
So let's search a package here now.
Before downloading this software package, you can check whether the package you need is available from
your repository or not, which has placed you where your operating system stays.
Stores information The APC tool has a search function that can check whether the packages available,
so the syntax is informative to NPR team.
Check here.
Search Keyword here.
For example, a key tool and, for example, search Chrome.
As you can see here, we have so many from here.
Cro-Magnon, Sheryl Crow, Muma and others.
Or we can search.
Senator.
Let's see here.
So now I want your adding software to it now that, you know the snort package here.
Um.
As you can see here, exist in your story, so you can use APT, get to download the software to install
a piece of software from your operating systems default repository in the terminal, use the APT get
command, followed by the key word installed here install and then the name of the package you want
to install.
The syntax will look like that, for example, the name of the package here, so let's install small
theater arts.
So if you get error like that odd pseudo promotion, so run this command, which should have permissioned
and interior kelly passport here and as you can see here.
And after all these, uh, operation ten point five megabyte of additional disk space will be yours.
Do you want to continue for this year and enter?
Yes and no.
Now Francis is demanding.
Yes.
As you can see, his snot is installed now.
As you can see, eBay started snored as well.
But I will quit now.
Actually.
So.
We can't remove packages, so you will remember in pictures in Linux, no.
So when removing a software news API to get with the removal option followed by the name of the software
to remove.
So if I want to remove snored here small remove snore care.
Uh, if you get this error, uh, just uh, the pseudo here.
And your county?
A password and a Kindle, yes.
Yes.
So we removed our snort with three more comment here, but again, you will see the task being done
in real time and you will be asked whether you want to continue or not.
So you can enter year two one install and end to, um, keep snorts of signs we will be using again.
So, no, but I removed it, so I will instantly snort again and putting it in remove, snort I to get
install, snort here we will.
I have another, uh, software removing a comment here and you will see it.
And now?
