为Linux terminal配置时间分隔线

linux

PS 之前看ning弄得挺漂亮的，今天小折腾一下分隔线。

reference
为OSX和Linux的TERMINAL增加时间分割线

先上效果

网上能够搜到code，就是不同的系统好像要放在不同的文件下。
我的是Ubuntu 12.04:

cd home/username //注意要ls -a才能看到隐藏的.bashrc
cp .bashrc .bashrc-backup//先存一份原来的配置，方便改回来
sudo gedit home/username/.bashrc //username是自己的用户名字

然后把下面的代码放在.bashrc的后面
