Open .pdf on ubuntu

转自:http://blog.sina.com.cn/s/blog_4b25dd230101bvzl.html

Use：

    gnome-open file2open.pdf     //With this command gnome will invoke the default app for "xxx" (for example evince if you want to open pdf).

Or

    evince file2open.pdf

To make it convenient, u can also set

    alias open='gnome-open'

Then u can just use:

    open file2open.pdf
(转载后经测试ubuntu13.10要另外执行apt-get install libgnome2-bin)
