Apt-get command in Linux with Examples. Apt-get is a command-line tool which helps in handling packages in Linux. Its main task is to retrieve the information and packages from the authenticated sources for installation, upgrade and removal of packages along with their dependencies. Here APT stands for the Advanced Packaging Tool.

APT-GET and APT-CACHE Commands What is apt-get? The apt-get utility is a powerful and free package management command line program, that is used to work with Ubuntu’s APT (Advanced Packaging Tool) library to perform installation of new software packages, removing existing software packages, upgrading of existing software packages and even used to upgrading the entire operating system. Load in your IP, give it a name and save config. Load the saved settings and Open. Accept the SSH key. Login to your Debian machine remotely with your username and password. Enter 'su' on the command line, then put in root password. You should be at root on your debian, denoted by “root@ hostname:#”.

When I was a complete beginner and I needed to install something on my Ubuntu machine, I went online and typed in “How to install <software name> on Ubuntu” and it led me to a page with some commands which looked like this

I was just happy that I was able to type something in the Terminal and that it actually worked and did what I wanted it to do! I did not pay much attention to what I actually typed in. I guess to beginners, it just feels like a magic spell to get something installed!

In this article, I have tried to explain what this command means from a beginner’s perspective avoiding unnecessary “technical terms” and I have tried to keep this article concise so that you can get through the entire article in about 10 to 20 mins max!

Let us see what this command does, how it does that, and the reason you need to do this every time you need to install an app on your Linux computer.

For those of you in a hurry, here is the short version of the answer!

The Short Version of the Answer

What is the meaning of the command “sudo apt-get install“?sudo apt-get install command is used to download the latest version of your desired application from an online software repository pointed to by your sources.list configuration file and and installthat application on your Linux machine.

I can see that the above paragraph has too many “technical terms” (which I promised not to use!) but that is just the short version of the answer to explain the command “sudo apt-get install“, so do not worry if you don’t understand every word in that paragraph!

By the end of this article we will get back to this short answer version and by that time I am sure you will be able to understand what every word meant in the short answer above!

So let us begin!

sudo apt-get install

Let us start by exploring the answer to the question “What does apt-get do?”

The apt-get command is responsible for installation, removal, and updating of software in our system.

A good analogy is to think of your computer as a factory and the apt-get command as the manager in that factory who is responsible for the installation of new equipment, removal of equipment that is no longer needed, and update desired equipment to their latest versions, while maintaining records of the equipment names and versions which are currently present in the factory.

In the screenshot below I am trying to install an app named gedit, which is basically a text editor

Your output might look a bit different than mine, but the important things to note here are the first 2 lines.

Continuing with our “factory analogy”, if you “the factory owner” orders the manager to install a conveyor belt, the manager is smart enough to understand that you need an entire conveyor system, and you expect him to install everything for you.

Let’s assume the manager has a list of files with given to him by all the equipment part manufacturers about what parts each of them produce. So naturally, the first thing the manager will do is to have a look at the documents given by all the equipment manufacturers and information required regarding what are the parts available with each of them which are necessary to build the conveyor system.

As you can see the first line in the screenshot above says “Reading package lists… Done” which means that apt-get went ahead and read all the available software in the repos.

The next thing the manager need to do is to go ahead and do the research of what are the parts needed for the conveyor and make a shopping list.

As you can see, the second line in the screenshot says “Building dependency tree” which means the apt-get is trying to see which other packages are required to make our desired package, gedit to run.

You cannot install a belt for the conveyor, before installing the rollers and the conveyor motors, because a belt depends on the presence of a conveyor motor and a roller to do its job, hence roller, sensors and motors are dependencies for a conveyor belt!

Then once apt-get knows what software to download and where to download them, apt-get tells us what additional packages will be downloaded and installed and how much extra space will be needed. Once we confirm this list by typing the letter “Y” and press enter, apt-get will download and install everything for us.

This prompt can be thought of as the factory manager asking you to confirm if you are okay with the list of things that need to be bought, and how much space they will these parts occupy once you install a conveyor system in your factory.

If you still have an “incomplete feeling” about what this command means, read on for a longer and more informative answer where I explain the answers to the following questions

Command Line Interface vs Graphical User Interface: What is the need to have these 2 interfaces?
What is a command-line?
What do the 3 words in our command (sudo, apt-get, and install) mean?
Why do we need this command before we install software? and
Where to get more information about these commands?

So let us carry on with our exploration of the Linux world!

Let us start by exploring the world of text-based command line interface!

Command Line Interface vs Graphical User Interface

Let us first begin with this basic question of why use the command-line interface in the first place!Why not simply download and install an app instead?

As you might already know there are 2 types of ways for us to interact with the computers

Through the Graphical User Interface, a.k.a GUI and
Through the Command Line Interface, a.k.a CLI

But, what is an “Interface”?

Interface

Interfaces can be thought of as the middleman between you and the machine, a way to make the machine understand what your wishes are. A TV remote is a good example of an interface, as this device acts as a middleman between you(the human) and your TV(the machine). Using a remote you can interact with your television, hence your TV remote is an interface!

Graphical User Interface

The graphical user interface is the interface we are all familiar with, where we use our mouse or the touch screen to click through various icons and perform the desired action on our computers. This interface was made to make the operations on computers easier for regular users who might not be as tech-savy as programmers or software engineers.
