DMRIDUpdate.sh script para atualizar o MMDVM hotspot Pi-Star

Este é um pequeno script shell que pode ser utilizado para atualizar o arquivos de DMR id's e mostrar nas telas Nextion, ou outras, normalmente utilizando com NextionDriver (normalmente ele não vem instalado na instalação padrão do Pi-Star. Necessário consultar este link)

# On a Linux based system, such as a Raspberry Pi, this script will update the
# stripped.csv and DMRIds.dat files.
#
# It is designed to run from crontab and will download the latest IDs from the 
# master DMR-MARC ID database and optionally keep a backup of previously
# created files for you.
#
# It will also prune the number of backup files according to a value specified
# by you in the configuration below.
#
# After restarting the hotspot, the changes will be loaded.
#
# To install in root's crontab use the command ...
#
#     sudo crontab -e
#
# ... and add the following line to the bottom of the file ...
#
#     0  0  *  *  *  /root/DMRIDUpdate.sh 1>/dev/null 2>&1
#
# (change root to wherever you placed the script)
