  • How to Update Arch Linux
  • The command pacman -Sy synchronizes the package list with the master server. This server/client model also allows the user to download/install packages with a simple command, complete with all required dependencies1. However, it is important to note that when installing packages in Arch, you should avoid refreshing the package list without upgrading the system (for example, when a package is no longer found in the official repositories). In practice, do not run pacman -Sy package_name instead of pacman -Syu package_name, as this could lead to dependency issues. See pacman.

  • The Ultimate Guide to Pacman Commands on Arch Linux
  • Do we normally need to add sudo beforec running pacman?
    • Yes, you normally need to use sudo when running pacman commands that modify the system, such as installing, updating, or removing packages. This is because these actions require administrative privileges.
    • For example, to update your system using pacman, you would run the command sudo pacman -Syu. Similarly, to install a package, you would use the command sudo pacman -S package_name.
    • However, some pacman commands do not require administrative privileges and can be run without sudo. For example, you can use the pacman -Q command to view information about installed packages without using sudo.
  • To view a list of all explicitly installed packages (i.e., packages that were not installed as dependencies)
    pacman -Qe
    

    To view a list of all installed packages from the AUR, you can use the command pacman -Qm

  • display information such as the package version, description, dependencies, and more
    pacman -Qi r
    
  • display a list of all files installed by the package
    pacman -Ql r
