GKD认证脚本

更新日志：

v0.1：登录方式源码脚本开始编改

执行脚本：./giwifi.sh 账号 密码

v0.2：添加sh存储账号密码功能

创建执行文件 ：vi giwifi.sh

复制粘贴下方代码

按键盘ESC 键盘输入 :x 保存

给予文件全部权限执行 chmod +x giwifi.sh

然后就可以 ./giwifi.sh开始登录啦！

[root@root AM ~]  #vi 1.sh
[root@root AM ~]  #chmod +x 1.sh
[root@root AM ~]  #./1.sh

最后更新时间：2024年4月6日

GitHub连接：等待更新

wget下载链接：等待更新

v0.2精简版(只有登录功能):理论上这个就够了
