Spring boot jar启动，停止

linux 以jar的形式部署Spring boot ，用脚本管理项目的启动，停止。
shell 脚本：

version="1.0.1";

appName=$2
if [ -z $appName ];then
    appName=`ls -t |grep .jar$ |head -n1`
fi

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 $appName is starting..."
		nohup java -jar ./$appName -XX:+UseG1GC -XX:+HeapDumpOnOutOfMemoryError -Xms512M -Xmx4G > /dev/null 2>&1 &
	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 "The $appName is stopping..."
        kill $appId
	fi
}

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
}

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
}

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 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;;
