1.可选择输出到控制台还是后台运行

红色为注意更改路径

把 stdout 送到 /dev/null（无底洞）里面，就不会输出到前台。 2.这是直接输出到控制台，是上面.sh的简化版

    PID=`echo $PIDLIST | cut -c0-5`
    if [ -n "$PID" ] ; then
      echo "Killing process $PID ..."
      kill -9 $PID
    else
      echo "PCRF_SMS_Mediator Program is not running. Nothing to kill!"
    fi
    exit 1

elif [ "$1" = "status" ] ; then
    PIDLIST=`ps --width 2000 -fu $USER | grep -v "grep" | grep "$Application_HOME" | cut -c9-14`

    fi
    exit 1
fi
