Imagine that you have a program named simpleserver , which is written as a traditional Unix daemon, in other words, it forks and runs in the background: the code for such a program is in MELP/chapter_10/simpleserver. You will need an init.d script like this, which you will find in MELP/chapter_10/simpleserver-sysvinit:

#! /bin/sh case "$1" in   start)     echo "Starting simpelserver"     start-stop-daemon -S -n simpleserver -a /usr/bin/simpleserver     ;;   stop)     echo "Stopping simpleserver"     start-stop-daemon -K -n simpleserver     ;;   *)     echo "Usage: $0 {start|stop}"   exit 1 esac  exit 0
