GKD認證指令碼

更新日誌：

v0.1：登入方式原始碼指令碼開始編改

執行指令碼：./giwifi.sh 賬號 密碼

v0.2：新增sh儲存賬號密碼功能

建立執行檔案 ：vi giwifi.sh

複製貼上下方程式碼

按鍵盤ESC 鍵盤輸入 :x 儲存

給予檔案全部許可權執行 chmod +x giwifi.sh

然後就可以 ./giwifi.sh開始登入啦！

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

最後更新時間：2024年4月6日

GitHub連線：等待更新

wget下載連結：等待更新

v0.2精簡版(只有登入功能):理論上這個就夠了
