cylon is installed by PKGBUILD on a Arch based Linux system. The PKGBUILD file is available in the AUR - Arch user repository. Install it using an AUR helper program or installations instructions on Arch user repository page of Arch linux wiki. The program will work on any arch based system. Arch, manjaro, antergos etc.

• AUR package name : cylon
• AUR maintainer : glyons
• AUR location: https://aur.archlinux.org/packages/cylon/

The program installs an icon in system application menus under system. It can be also run in a terminal by typing cylon:

cylon -[options]

Options list (standalone cannot be combined):

Cylon files installed by package build are listed below:

README.md is displayed to screen by a menu option on cylon info page. Type "man cylon" to display manpage. The manpage is a truncated version of the readme file. More information on the modules files can be found in modules_info.md in documentation folder.

Config file: The user can create an optional config file, used mainly for custom system backup. If the user is not using the system backup option or ccrypt menu function or custom clamav scan option, the user does not need config file.

• NAME: cylonCfg.conf
• PATH: $HOME/.config/cylon/cylonCfg.conf This Path can be overwritten by environmental variable see next section.
• SETTINGS: "DestinationX" is the path for backups. "gdrivedestX" is remote google drive directory file ID (see gdrive readme for setup and how to get file id numbers) and "gdriveSourceX" is the local directory source. "rsyncsource" and "rsyncdest" provide the source and destination paths for rsync option in backup menu. "myccfile" is a setting for ccrypt utility, a path to a default file for ease of use. If config file missing the System uses hard-coded dummy defaults. The config file can be edited from a main menu option or by option -c

cylonCfg.conf file setup example: Just copy and paste this into file and change paths for your setup. alternatively a config file template with dummy values is in documentation folder of the repository.

Destination1="/run/media/$USER/Linux_backup"

Destination2="/run/media/$USER/iomega_320"

gdriveSource1="$HOME/Documents"

gdriveSource2="$HOME/Pictures"

gdriveSource3="$HOME/Videos"

gdriveSource4="$HOME/.config"

gdriveDest1="foo123456789"

gdriveDest2="foo125656789"

gdriveDest3="foo123666689"

gdriveDest4="foo123662222"

rsyncsource="$HOME/"

rsyncDest="/run/media/$USER/Linux_backup/foo"

myccfile="$HOME/TEST/test.cpt"

clamav_customdir="$HOME/Downloads/foo"

CYLONDEST, CYLON_CONFIG and CYLON_COLOR_OFF are three optional custom environmental variables used by program. If variable CYLONDEST and CYLON_CONFIG are not set or do not exist, cylon uses the default path. CYLON_COLOR_OFF is used for turning off colored text output. For information on setting environment variables see arch linux wiki.

CYLONDEST

Most system output (logfiles, downloads and updates etc) is placed at below path, unless otherwise specified on screen. Output folders are created with following time/date stamp syntax HHMM-DDMONYY-X where X is output type i.e download, update etc. The default path is:

$HOME/Documents/Cylon

This optional Environment variable is provided for users who wish to use different destination path for program output folder.

CYLON_CONFIG

The default path for config file is

$HOME/.config/cylon/cylonCfg.conf

This optional Environment variable is provided for users who wish to use different destination path for program config file.

CYLON_COLOR_OFF

if it does not exist or is not set cylon uses colored output. This optional Environment variable is provided for users who wish to see no colour in terminal. Set it equal to "on"

EDITOR "nano" is used as default text editor for editing config files IF $EDITOR user environment variable is not set.

$EDITOR

Some functions require dependencies packages to be installed. There are two dependencies and the rest are optional dependencies. The optional dependencies are left to user discretion. Software will check for missing dependencies and report if user tries to use a function which requires a missing one. Software will display installed dependencies packages on cylon info page. also "n/a" is usually displayed besides uninstalled options in menus.

gnu-netcat and openbsd-netcat peform same function, only 1 can be or needs to be installed, both included because of conflicts. There are used to check that network is "up" at various points in program.

Auracle and trizen are both AUR helpers you can install one or both depending on preference. Auracle is a more minimalist helper. trizen is more fully featured. Auracle is recommended as in addition to menu options it is used for -u and -n functions, plus step 24 of the package list maker(REF1) Auracle is new and still in development hence the -git extension, it replaced cower in version 5.1-3, as cower is obsolete. Trizen replaced pacaur in version 5.2-4 as pacaur is no longer maintained and is a wrapper of cower. The original pacaur and cower code modules are still available in documentation folder for reference.

libnotify should be installed on the vast majority of Arch systems already.

gdrive readme for config https://github.com/prasmussen/gdrive , gdrive option syncs will Delete extraneous remote files as of V3.4-5.

dialog should already be installed in an arch linux system installed by the arch linux installation guide on wiki. If you install Arch some other way It may not be there, so included as depends.

expac is used a lot and will be already installed on many systems.

The program functions are divided into 6 sections: update, maintenance, backup, security, network and miscellaneous.

The update section is the core of the program and provides a wrapper for pacman, trizen and auracle. It provides an extension to auracle to allow it to install and update packages. It also provides a full system update report function and various other options.

The maintenance section provides a variety of scans and checks, it also a provides command line wrapper for rmlint and bleach-bit.

The backup section provides a wrapper for gdrive program. as well as ability to backup system using various tools.

The security section provides a wrapper for ccrypt and an extended launcher for various security tools as well as a password generator.

The network section provides various tools to check network and configuration.

Other misc functions include an option to edit config file, information menus for system and cylon. Weather forecast and terminal launcher.
