My script is attached.  It runs every minute from cron.  I think I
copied it off the mythTV wiki or something.


pidno=$( ps ax | grep /usr/bin/mythbackend | grep -v grep | grep -v
# Checks for pid in "ps" listing, field #1.
# Then makes sure it is the actual process, not the process invoked by
this script.
# The last "grep $1" filters out this possibility.
if [ -z "$pidno" ]  # If, after all the filtering, the result is a
zero-length string,
then                # no running process corresponds to the pid given.
  echo "No such process running."

  /etc/init.d/mythtv-backend restart
