RokasYang's Blog写这个脚本的目的完全是为了检测网站安全性，希望大家别拿去做坏事哈~主要用于批量扫描目标端口开放情况与探测服务版本等，速度上也做了很大程度的优化，靠后台进程来实现多线程扫描。
缺点:当目标大于300个的时候，会出现后台进程一直处于等待状态，扫描结果也会漏掉30-60个左右。所以你可以分批扫描，使用crontab定时批量切换文件扫描，如果你觉得有更好的方式去实现与改进可以随时与我联系。
以下是脚本源代码:

wget 'https://www.linux-code.com/wp-content/uploads/2018/05/test.sh'那么怎么去执行该脚本，以及文件格式是什么呢？
你只需要：
bash test.sh -f file
注意file(文件可以任意指定)的格式必须是ipaddress:port形式，比如:
127.0.0.1:80
192.168.1.1:23
45.32.117.7:443
可以看到，扫描17个目标端口和服务版本耗时18.89秒，速度惊人，同时扫描结果保存到了时间格式的.RESULT文件中:
注意:
本脚本可能存在一定Bug,或者您觉得还有可以优化的地方，都可以联系我:
