linux脚本归纳

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

                done
                LCP=$Application_HOME/conf/:$LCP
                Application_CMD="$JAVA_HOME/bin/java -classpath $LCP:$Application_HOME/resource $Main_Class"

        echo "  status            Show the status of $Application_Name program"
        exit 1
fi

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

Application_HOME="/data/onepns/docroot/SMPP_HPNS/PCRF_SMS_Mediator"
JAVA_HOME="/usr/java/default/"


#-------------- Simple Grep -----------------------------
if [ "$1" = "stop" ] ; then
		echo "Stopping SMPPModule Program ..."
		PIDLIST=`ps --width 2000 -fu $USER | grep -v "grep" | grep "$Application_HOME" | cut -c9-14`
		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`
		PID=`echo $PIDLIST | cut -c0-5`
		if [ -n "$PID" ] ; then
			echo "PCRF_SMS_Mediator Program is running (PID=$PID)"
		else
			echo "PCRF_SMS_Mediator Program is not running."
		fi
		exit 1
fi


#-------------- The part below need java ---------------------
for i in $Application_HOME/lib/*.jar
do
  # if the directory is empty, then it will return the input string
  # this is stupid, so case for it
  if [ "$i" != "$Application_HOME/lib/*.jar" ] ; then
    if [ -z "$LCP" ] ; then
      LCP=$i
    else
      LCP="$i":"$LCP"
    fi
  fi
done

LCP=$Application_HOME/conf/:$LCP
