Recently switched to Arch Linux as your daily driver? Great! I've got a good news for you. Meet Cylon, a maintenance program for Arch Linux and derivatives. It is a menu-driven Bash script which provides updates, maintenance, backups and system checks for Arch Linux and its derivatives such as Manjaro Linux etc. Cylon is mainly a CLI program, and also has a basic dialog GUI. In this guide, we will see how to install and use Cylon in Arch Linux.
Cylon - The Arch Linux Maintenance Program
Cylon is available in the AUR. You can install it using any AUR helpers, for example Yay.
$ yay -S cylon
Please note that Cylon will not install all tools by default. Some functions require various dependencies packages to be installed. There are three dependencies and the rest are optional dependencies. The optional dependencies are left to user discretion. When you perform a function, it will display the missing packages if there are any. All missing packages will be shown as n/a (not available) in menus. You need to install the missing packages by yourself before using such functions.
