pacman --sync

Arch Linux package manager utility. See also: pacman. More information: https://man.archlinux.org/man/pacman.8.

• Install a new package:

sudo pacman --sync {{package_name}}

• 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_name}}

• Search the package database for a regular expression or keyword:

pacman --sync --search "{{search_pattern}}"

• Display information about a package:

pacman --sync --info {{package_name}}

• 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_name}}

• Remove not installed packages and unused repositories from the cache (use two --clean flags to clean all packages):

sudo pacman --sync --clean
