linux 查看某进程并强制杀进程并重启

# 定义变量 process 值是 Hello.jar
process=Hello.jar
# 打印 进程单一 jar进程
pid=$(ps -ef |grep $process|grep -v grep|awk '{print $2}')
if [ ! $pid ]; then 
        echo "当前已无进程"
else 
        echo "$process 当前进程 $pid , 杀掉进程 $pid"
        kill -9  $pid
        echo "进程已停止..."
fi
echo "重启进程..."

pid=$(ps -ef |grep $process|grep -v grep|awk '{print $2}')
echo "当前进程 $pid , 启动成功..."
