Pacman is the default package manager for Arch Linux and its derivatives. It is a powerful tool that allows users to install, remove, and manage packages on their Linux system. Pacman is designed to be simple and efficient, with a focus on stability and reliability. It is a command-line tool that uses a package database to keep track of installed packages and their dependencies.
Overview
Pacman is used to install, remove, and manage packages on an Arch Linux system. It can be used to search for packages, upgrade the system, and synchronize the package database with remote repositories. Pacman is also capable of resolving dependencies between packages, ensuring that all necessary packages are installed before a package is installed.
