最近部署项目写了一个shell脚本用于文件夹内jar文件的一键启动和停止，包括状态查询等；和大家共享一下！

贴上代码：

#!/bin/bash
    version="1.0.1";
    
    JAVA=java
    JAVA_HOME=/opt/jdk1.8
    JAVA=$JAVA_HOME/bin/java
    
    appName=$2
    if [ -z $appName ];then
        appName=`ls -t |grep .jar$ |head -n1`
    fi
    
    #一键启动
    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 $JAVA -Xmx2048m -Xms1024m -XX:PermSize=512M -XX:MaxNewSize=512M -XX:MaxPermSize=1024M -jar ./$appName > ./console.out 2>&1 &
    	fi
    }
    
    #一键结束
    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 "The $appName is stopping..."
            kill $appId
    	fi
    }
    
    #一键重启
    function restart()
    {
        # get release version
        releaseApp=`ls -t |grep .jar$ |head -n1`
        
        # get last version 
        lastVersionApp=`ls -t |grep .jar$ |head -n2 |tail -n1`
    
        appName=$lastVersionApp
        stop
        for i in {5..1}
        do
            echo -n "$i "
            sleep 1
        done
        echo 0
        
        backup
        
        appName=$releaseApp
        start
    }
    
    #一键备份
    function backup() 
    {
        # get backup version
        backupApp=`ls |grep -wv $releaseApp$ |grep .jar$`
        
        # create backup dir
        if [ ! -d "backup" ];then
            mkdir backup
        fi
        
        # backup
        for i in ${backupApp[@]}
        do
            echo "backup" $i
            mv $i backup
        done
    }
    
    #状态查询
    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
    }
    
    #菜单
    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;;
