Pacaur is a command line package manager for Arch Linux, based on the popular cower package manager. It is designed to be an easy to use and efficient tool for finding, installing and upgrading packages from the Arch User Repository (AUR). It is powered by the Pacman package manager, which is the official package manager for Arch Linux. Pacaur is a great way to download and install packages from the AUR, as it is simple to use and supports multiple concurrent downloads. It also offers a wide range of options and features such as package search, dependency resolution, package verification, and more.
