  sudo pacman --sync {{package}}
• Synchronize and update all packages (add --downloadonly to download the packages and not update them):
  sudo pacman --sync --refresh --sysupgrade
• Update all packages and install a new one without prompting:
  sudo pacman --sync --refresh --sysupgrade --noconfirm {{package}}
• Search the package database for a regular expression or keyword:
  pacman --sync --search "{{search_pattern}}"
• Display information about a package:
  pacman --sync --info {{package}}
• Overwrite conflicting files during a package update:
  sudo pacman --sync --refresh --sysupgrade --overwrite {{path/to/file}}
• Synchronize and update all packages, but ignore a specific package (can be used more than once):
  sudo pacman --sync --refresh --sysupgrade --ignore {{package}}

  sudo pacman --sync --clean
