pacman

Arch Linux package manager utility.

Some subcommands such as `pacman sync` have their own usage documentation.

• 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
