====== Cron jobs ffp script ======
Supposing you already know what cron is, here is how you enable cronjobs on your NAS. Below are two ffp scripts, one for enabling the service, and the other for cronjobs.

===== /ffp/start/crond.sh - The service =====

  #!/ffp/bin/sh
  
  # PROVIDE: crond
  # REQUIRE: LOGIN
  
  . /ffp/etc/ffp.subr
  
  name="crond"
  start_cmd="crond_start"
  stop_cmd="crond_stop"
  status_cmd="crond_status"
  
  crond_start()
  {
    cronfile=/var/run/crond.pid
    
    #get the pid, if it exists
    if [ ! -f $cronfile ];then
      crond -b -L /mnt/HD_a2/logs/cron.log
      return
    fi
      thispid=`cat $cronfile`
    if [ ! -d /proc/$thispid ];then
      crond -b -L /mnt/HD_a2/logs/cron.log
      return
    else
      echo "crond is already running"
    fi
  }
  
  crond_stop()
  {
    cronfile=/var/run/crond.pid
    
    #get the pid, if it exists
    if [ ! -f $cronfile ];then
        echo "crond is not running"
        return
    fi
        thispid=`cat $cronfile`
    if [ ! -d /proc/$thispid ];then
        echo "crond is not running"
    else
        kill -9 $thispid
    fi
    
  }
  
  crond_status()
  {
    cronfile=/var/run/crond.pid
    
    #get the pid, if it exists
    if [ ! -f $cronfile ];then
      echo "crond is not running"
      return
    fi
    thispid=`cat $cronfile`
    if [ ! -d /proc/$thispid ];then
      echo "crond is not running"
    else
      echo "crond is running normally"
    fi
  }
  
  run_rc_command "$1"



===== /ffp/start/cronjobs.sh - Jobs =====

  #!/ffp/bin/sh
  
  # PROVIDE: cronjobs

  . /ffp/etc/ffp.subr
  
  name="cronjobs"
  start_cmd="cronjobs_start"
  stop_cmd="cronjobs_stop"
  status_cmd="cronjobs_status"
  
  cronjobs_start()
  {
    # Report jobs log to an email address
    echo "EMAIL=" > /tmp/cronjobs
    
    # Job 1 - Example that will download latest set of ffp packages automatically
    echo "0 0 * * * /ffp/bin/rsync -av inreto.de::dns323/fun-plug/0.5/packages /mnt/HD_a2 > /mnt/HD_a2/rsync_ffp_packages.log" >>/tmp/cronjobs
    
    # Import jobs to service
    crontab /tmp/cronjobs
    echo "setting the following cron jobs:"
    cat /tmp/cronjobs
    rm /tmp/cronjobs
  }
  
  cronjobs_stop(){
    echo "" >>/tmp/cronjobs
    crontab /tmp/cronjobs
    echo "removing all cron jobs"
    rm /tmp/cronjobs
  }
  
  cronjobs_status()

    echo "status not available"
  }
