# On a Linux based system, such as a Raspberry Pi, this script will perform all
|
|
# the steps required to maintain the DMRIds.dat (or similar) file for you.
|
|
#
|
|
# 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.
|
|
#
|
|
# When done, it will restart MMDVMHost to make the ID changes take effect.
|
|
#
|
|
# 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 * * * /path/to/script/DMRIDUpdate.sh 1>/dev/null 2>&1
|
|
#
|
|
# ... where /path/to/script/ should be replaced by the path to this script.
