The easiest way to view a complete list of packages that are installed on your Ubuntu or Debian system is to use the dpkg --get-selections command like this:
dpkg --get-selections > ~/installed_packages.txt
The command dpkg --get-selections simply returns a list of all the packages installed via apt. The above command will put the entire list inside your home directory, in the file installed_packages.txt, so you will be able to read it using a text editor.Source URL: http://ashesgarrett.blogspot.com/2008/10/tip-of-day-view-what-packages-are.html
