Pacman Command on Arch Linux – Getting Started

Every Linux distribution ships with a command line Package Manager, which can be used to install applications from the Terminal or command line interface. Ubuntu has the APT package Manager, Red Hat uses YUM and DNF and Zypper on OpenSUSE.

Pacman is the default CLI tool on Arch Linux and its derivative distributions for installing packages via the command line. It is really simple to use and the focus of this tool is to ‘type less and do more’ and thus you don’t have to write pacman-get install <package name> to install any application, instead just do pacman -S <package name>.

We will look at the usage of this command in detail in this article.

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 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 update your packages.

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