pacman

The package manager for Arch Linux and its derivatives, known for speed and terse flags like pacman -Syu.

What Is pacman in Linux?

Pacman combines operations into single-letter flags: -S syncs (installs), -y refreshes databases, -u upgrades, -R removes, and -Q queries installed packages. Always upgrade the whole system with -Syu rather than installing against a stale database.

Official repos cover a lot, and the AUR fills the gaps with community build scripts.

Example

sudo pacman -Syu
pacman -Qe
