pacman

 
Arch Linux package manager utility. Some subcommands such as pacman sync have their own usage documentation. More information: https://man.archlinux.org/man/pacman.8.
 
  • Synchronize and update all packages:
     
    sudo pacman --sync --refresh --sysupgrade
     
  • Install a new package:
     
    sudo pacman --sync {{package_name}}
     
  • Remove a package and its dependencies:
     
    sudo pacman --remove --recursive {{package_name}}
     
  • Search the package database for a regular expression or keyword:
     
    pacman --sync --search "{{search_pattern}}"
     
  • List installed packages and versions:
     
    pacman --query
     
  • List only the explicitly installed packages and versions:
     
    pacman --query --explicit
     
  • List orphan packages (installed as dependencies but not actually required by any package):
     
    pacman --query --unrequired --deps --quiet
     
  • Empty the entire pacman cache:
     
    sudo pacman --sync --clean --clean
