if you don't mind an example without the context, where you have to
extract the principle yourself:


#!/bin/sh

ERS=`ps -eaf | grep ersjsf | wc -l`

if [ $ERS -eq 2 ] || [ $ERS -eq 3 ]
  then
    /bin/echo "ERS OK - ERS running"
    exit 0
fi

if [ $ERS -eq 1 ]
  then
    sleep 20
    ERSLATE=`ps -eaf | grep ersjsf | wc -l`
    if [ $ERSLATE -eq 1 ]
      then
        /etc/rc2.d/S99ers start
      else
        /bin/echo "ERS OK - ERS running" 
        exit 0 
    fi
    /bin/echo "ERS CRITICAL - not running, attempted to restart"
    exit 2
fi
