Arch Linux
is a Linux distribution that is created for simplicity, optimization, modernity, pragmatism, user centrality, and versatility. Arch Linux is different from the mainstream distributions like Debian, Ubuntu, Mint, Kali, Fedora, CentOS, RHEL, and SUSE with its package management system and philosophy. Arch Linux adopts the rolling release model which means there are no a milestone or major releases for new versions.
Arch Linux History
Arch Linux is inspired by CRUX Linux distribution which is simple and efficient. Judd Vinet started the Arch Linux project in March 2002. Originally the first version was compatible with the 32-bit x86 architecture but x86_64 support came in April 2006. The Arch Linux creator Vinet stepped down and transferred the project to the “Aaron Griffin” in October 2007. In February 2020, Aaron Griffin transferred the project to the Levente Polyak. The 32-bit support is dropped in January 2017.
Arch Linux Design and Principles
Arch Linux is based binary packages which are compiled for speed on modern hardware. Also ports/ebuild-like system is provided for automated source compilation for customization and speed. Arch Linux focuses on simplicity with less details without providing polished interfaces and actions. As an example the package manager Packman do not have any official GUI front-end to make things simpler and straightforward. The system configuration is simple and clean which can be transferred into different versions. This made the Arch Linux popular between “advanced users” and “geeks” popular who are eager to use command line.
Arch Linux Package Manager – Pacman
Which makes the Arch Linux from other Linux distributions is its package manager named Pacman. The term “Pacman” is the joint form of “package manager”. Pacman is a command like a package manager used to install, update, remove, and manage packages and repositories. The Arch Linux package repositories and User Repository (AUR) contain 58,000 binary and source packages. Pacman is created by Judd Vinet and written in C programming language. Packages are generally compressed with “xz”. Arch Linux has different types of repositories like below.
Core

Extra
