# 
# setup:
#   1. create the /boot/config/custom/rsyslog.d/ folder on your flash drive
#   2. place this script in that folder, name it rsyslog_copy
#   3. add this line to the top of your go script (before starting emhttp):
#      bash /boot/config/custom/rsyslog.d/rsyslog_copy
#
# to test new rsyslog filters:
#   * add or edit a .conf file in /boot/config/custom/rsyslog.d/
#   * then at the shell type:
#      bash /boot/config/custom/rsyslog.d/rsyslog_copy
#   * this will copy the .conf file and restart rsyslogd if it is running
#   * then review your local syslogs at /mnt/user/system/ (or wherever you have configured them to go)
#
# note: the syntax for the filters is complex and beyond the scope of this script
#   see: https://www.rsyslog.com/doc/v8-stable/configuration/filters.html
