Epsilon

Epsilon (or epsi) is a powerful, lightweight, and easy-to-use package manager for AxOS. It is designed to be simple to use, and to provide an easy way to install, update, and remove packages on your system.

Epsilon fetches packages from the pacman repositories and the AUR, and can install packages from both sources. It also provides a simple way to manage your system’s packages, and to keep your system up-to-date.

Installation

Epsilon comes pre-installed on AxOS, so you don’t need to install it separately. You can start using it right away.

Usage

Epsilon is a command-line tool, and can be used from the terminal. Here are the commands that you can use with Epsilon:

# Just install a package or a list of packages
epsi install <package1> <package2> ...
epsi i <package1> <package2> ...
epsi -S <package1> <package2> ...
epsi sync <package1> <package2> ...

# Install from a specific repo
epsi install <package1> <package2> ... --aur # installs the package from the aur
epsi install <package1> <package2> ... --repo # installs the package from the axos or arch repos

# Remove a package or a list of packages
epsi remove <package1> <package2> ...
epsi rm <package1> <package2> ...
