Pacman Package Manager – Getting Started With Pacman

Pacman Package Manager

The Pacman package manager is the default package manager for Arch Linux and other Arch-based distributions. It is one of the most feature-rich package managers out there and in this module, we are going to take a look at some of its functionalities.

What Is the Pacman Package Manager?

Pacman is a package manager utility for Arch Linux and its derivatives. It is written in C and combines a simple binary package format with an easy-to-use build system. The goal of pacman is to make it possible to easily manage packages, whether they are from the official repositories or the user’s own builds.

The pacman package manager works according to the client-server model with respect to the master servers, which allows the user to download/install packages with a simple command, complete with all required dependencies. It also helps you synchronize packages with the master servers and keep your packages updated.

Pacman comes with a lot of functionalities. However, in this module, we will learn how to :
