# Script to install SkywarnPlus. This script will determine the system type (ASL1/2, ASL3, or HamVoIP),
|
||||||
|
# install the required dependencies, download the latest version of SkywarnPlus from GitHub,
|
||||||
|
# configure the necessary permissions, and set up a crontab entry to run SkywarnPlus at a specified interval.
|
||||||
|
# This script also checks if the SkywarnPlus directory already exists and asks for user confirmation to remove it before continuing.
|
||||||
|
# Please note that this script should be run as root.
