后台启动java

一·后台启动java
./app.sh start

#!/bin/bash

appName=`ls|grep .jar$`
if [ -z $appName ]
then
    echo "Please check that this script and your jar-package is in the same directory!"
    exit 1
fi

killForceFlag=$2

function start()
{
        count=`ps -ef |grep java|grep $appName|wc -l`
        if [ $count != 0 ];then
                echo "Maybe $appName is running, please check it..."
        else
                echo "The $appName is starting..."
                nohup java -XX:+HeapDumpOnOutOfMemoryError -Xms512M -Xmx1024M -jar $appName > ./logs/log_console.log &
        fi
}

function stop()
{
        appId=`ps -ef |grep java|grep $appName|awk '{print $2}'`
        if [ -z $appId ]
        then
            echo "Maybe $appName not running, please check it..."
        else
        echo -n "The $appName is stopping..."
        if [ "$killForceFlag" == "-f" ]
        then 
            echo "by force"
            kill -9 $appId
        else
            echo
                kill $appId
            fi
        fi
}

function status()
{
    appId=`ps -ef |grep java|grep $appName|awk '{print $2}'`
        if [ -z $appId ] 
        then
            echo -e "\033[31m Not running \033[0m" 
        else
            echo -e "\033[32m Running [$appId] \033[0m" 
        fi
}

function restart()
{
    stop
    for i in {3..1}
    do
        echo -n "$i "
        sleep 1
    done
    echo 0
    start
}

function usage()
{
    echo "Usage: $0 {start|stop|restart|status|stop -f}"
    echo "Example: $0 start"
    exit 1
}

case $1 in
        start)
        start;;

        stop)
        stop;;

        restart)
        restart;;

        status)
        status;;

        *)
        usage;;
esac

二· 查找.jar放在哪里

ps -ef | grep java
find / -name xxx.jar
