   Here's a pipe which you can use to make sure that your important
daemons are re-born should they die (stick this in crontab).

   It's all one line, divided here for readability (how it works is
left as an exercise for the reader :-)

      ps -wwt\? | awk 'NR != 1 {print substr($0,21)}' | sort -u |
      comm -13 - /etc/phoenixtab | xargs -l /bin/sh -c

   /etc/phoenixtab is a list of the commands+args you don't want to
go away (SORTED!, 1 per line), like:

      /etc/bootpd -s -d
      /usr/foo/bar-o-matic -kludge
      /usr/lib/lpd
