Pimp my Elementary OS 5.0 (Juno)

Wie man das „alte“ elementary OS 0.4 (Loki) optimal anpasst hatte ich ja bereits hier und hier beschrieben. Seit dem 16.10.2018 ist nun die neue Version von elementary OS für alle verfügbar und damit auch Zeit für mich mein Skript zu aktualisieren…

Eine hervorragende Vorlage für kurze Bash-Skripte habe ich bei github gefunden. Mit „Yet another Bash script template“ (YABST) ging es super einfach.

Genug der langen Vorrede, hier der Code:

#!/bin/bash
##
## Usage: juno_post_install [options]
##
## Improve fresh elementary OS (juno) installation.
## Must be run as root.
##
## Options:
##  -h, --help      Display this message.
##  -v, --version   Display version number.
##
## Example:
## juno_post_install --help
##
