iPad2 利用3Proxy 分享 3G網路的 Shell Script(進階)

使用此腳本(script) 看不懂，請必須先了解前一篇(如下) ，並有Shell 的經驗方可學習。
手把手設定iPad 3G當無線網點代理伺服器 (PC -->iPad 3G -->外部網路)

要越獄 ，裝Cydia的套件
1) 3proxy
2) adv-cmds
若以上仍不夠，可能要再加Unix指令集的套件，因筆者裝了很多不知是否有少。

利用把iPad2當代理伺服器的方式，PC透過代理伺服器設定連網，並做一簡單的選單腳本。
Proxy port：3128
Socks port：1080
將下列腳存入p.sh並放在  /var/mobile 路徑，並利用root 改權限0755 及擁有者 mobile
./p.sh 執行
選單 有1)掛起代理 2)停止代理 3) 顯示狀態 0)離開。
筆者偷懶不想下太多指令給iPad壓力，所以寫個腳本省的老是一再掛了又殺。也可能畫蛇添足了，順便學學Shell Script，也學了好用的 Online 的 源碼轉Html的應用。
