dpkg is a tool to install, build, remove and manage Debian packages.
主要使用以下这两个功能：
-L|--listfiles <package> ... List files `owned' by package(s).
-l|--list [<pattern> ...] List packages concisely.
例子：比如我们想查找chrome浏览器的路径
@Ubuntu:~/myscript$ dpkg -l | grep chrome
ii google-chrome-stable 22.0.1229.94-r161065 The web browser from Google
ii xserver-xorg-video-openchrome 1:0.2.904+svn1050-1ubuntu0.1 X.Org X server -- VIA display driver
这样我们就能找到具体的正确的包名了，然后就是利用包名查找地址：
@ubuntu:~/myscript$ dpkg -L google-chrome-stable
