apt-get command in linux

Hello guys, Today I'm going to show you how you can use the "apt" command in linux. To Install, Remove and Manage packages in Debian based operating system.

Most of the Debian based operating system you can use "apt" command to install, remove and update packages in your system.

What is "apt" command?

"apt" is a command-line tool for working with an apt software package.

apt (Advanced Package Tool) available in Debian based operating system.

You need superuser privilege to use "apt" command so just use "sudo apt" because you are managing your packages in your system.

There are a bunch of commands which you can use with "apt",

Update all Packages

Update all Packages in your System

$sudo apt update

This command is going to re-synchronize your local package files to the remote server.

These package files are saved in a file called "sources.list". Which is in the location of "etc/apt/sources.list".

Install software/package

Install a Package in Linux

$sudo apt install packageName

For example, I want to install a package called "git". So I just need to type "sudo apt install git" and press ENTER.

Example

This command recognizes whatever extra software and dependencies this "git" package requires.

It's going to make a list of dependencies and software and also going to show you the amount of disk space it takes from your computer.

For example, This "git" requires "50.5 MB" of memory on my system and it going to ask whether you want to install it or not.

If you want to install it type "y" and press ENTER. Otherwise, type "n".

It takes some time depending on your internet speed to install.

Check Version

Check Version

$packageName --version

To check which version of software you have been installed by using a flag called "--version".

For example, Just say "git --version" and press ENTER. It will print the version.

Remove software/package

Remove Packages in linux

$sudo apt remove packageName

I want to remove the "git" package. So I just write "sudo apt remove git" and press ENTER. It's going to remove the package from my system.

Note:

But it's not going to remove configuratios from your system. It just remove the package only.

--purge flag

Remove configuration files

$sudo apt remove --purge packageName

To remove the configurations you need to use "--purge" flag. So just write "sudo apt remove --purge git" press ENTER.

It's going to remove all configuration files related to this "git".

Remove unwanted libraries

Remove unwanted Libraries

$sudo apt autoremove

There are some libraries and software which are not used by their parent software.

For this, you can use "sudo apt autoremove" command to remove all unwanted dependencies and libraries which are no longer needed.

It asks for confirmation to remove. Before removing just check the above libraries which are really necessary for you.

Conclusion

In this way you can use the "apt" command for Installing, Removing software and dependencies.

There are more flags you can use with this "apt" command. But these are the most frequently used commands in "apt".
