Something like this for monitoring the bash

#! /bin/bash

SERVICE='bmdstreamer.service'
LOGFILE='/var/log/bmdstreamer.log'

# If we catch anything new in the bmdstreamer log
while inotifywait -e modify $LOGFILE; do
    # Check if it's a 'no signal' event being logged
    if tail -n1 $LOGFILE | grep 'no signal'; then
	echo 'Attention! First time no signal from box. Checking...'
	# Avoid spurious 'no signal' events that might occur shortly after a first spurious one. Think on boot or (rarely?) in between.
	sleep 5s
	# Does another 'no signal' event occur within the next 10 seconds?
	inotifywait -e modify $LOGFILE -t 10 | while read path action file; do
	    if tail -n1 $LOGFILE | grep 'no signal'; then
		echo "Asking systemd to please restart $SERVICE"
                systemctl restart $SERVICE
	    fi
	done
