# A Control Script for SkywarnPlus
|
|
# by Mason Nelson (N5LSN/WRKF394)
|
|
#
|
|
#
|
|
# This script allows you to change the value of specific keys in the SkywarnPlus config.ini file.
|
|
# It's designed to enable or disable certain features of SkywarnPlus from the command line.
|
|
# It is case-insensitive, accepting both upper and lower case parameters.
|
|
#
|
|
# Usage: ./CONTROL.sh <key> <value>
|
|
# Example: ./CONTROL.sh sayalert false
|
|
# This will set 'SayAlert' to 'False' in the config.ini file.
|
|
#
|
|
# Supported keys:
|
|
# - enable: Enable or disable SkywarnPlus entirely. (Section: SKYWARNPLUS)
|
|
# - sayalert: Enable or disable instant alerting when weather alerts change. (Section: Alerting)
|
|
# - sayallclear: Enable or disable instant alerting when weather alerts are cleared. (Section: Alerting)
|
|
# - tailmessage: Enable or disable building of tail message. (Section: Tailmessage)
|
|
# - courtesytone: Enable or disable automatic courtesy tones. (Section: CourtesyTones)
|
|
#
|
|
# All changes will be made in the config.ini file located in the same directory as the script.
|
|
|
|
# First, we need to check if the correct number of arguments are passed
