dpkg(package manager for Debian): debian体系中的包管理工具。

Commands:
  -i|--install       <.deb file name> ... | -R|--recursive <directory> ...
-r|--remove        <package> ... | -a|--pending

1.查看已经安装的软件

$ dpkg -l

2.安装deb格式的软件

有时候会下载deb的软件，如virtualbox，那么我们就可以这样安装：

$ sudo dpkg -i virtualbox-4.3_4.3.26-98988~Ubuntu~raring_amd64.deb
