Linux下登錄新版TUNet的bash腳本

寫這個最初目的是做嵌入式的大作業的，因為TUNet更新了，所以不能做以前的那個mytunet的交叉編譯了。。。

腳本在Openwrt上測試通過。

把腳本中的your_username替換成info的用戶名，your_password_md5替換成你的密碼的md5，可以用echo -n your_password | md5sum來得到。另外腳本需要curl，Ubuntu用戶可以用sudo apt-get install curl來安裝。

代碼如下：

1. #!/bin/bash
2. # your info's username
3. uname=your_username
4. # your info's password's md5sum
5. pass=your_password_md5
