#+title:  pacman

The pacman [[id:b7c4f849-d1b1-4837-8634-82f6976a1473][package-manager]] is one of the major distinguishing features of Arch Linux and [[id:5fada795-19a3-4ba6-97c0-0b70bd728a2f][Arco-Linux]] . It 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.

Pacman keeps the system up-to-date by synchronizing package lists with the master [[id:f2b1d5af-1a7d-47a5-95c8-4a85d558419e][server]]. This server/[[id:70899526-8b7d-4976-94fc-cc07c41e550a][client]] model also allows the user to download/install packages with a simple command, complete with all required dependencies.
* Installing specific packages
To install a single package or list of packages, including dependencies, issue the following command:
#+begin_src bash
  pacman -S package_name1 package_name2
#+end_src
* upgrading packages
Pacman can update all packages on the system with just one command. This could take quite a while depending on how up-to-date the system is. The following command synchronizes the repository databases and updates the system's packages, excluding "local" packages that are not in the configured repositories:
#+begin_src 
 pacman -Syu
#+end_src
* ask no permissions
 #+begin_src 
 pacman -Suy --noconfirm
 #+end_src
