How to list all installed packages in Ubuntu

In Ubuntu, a list of all packages that are installed can be obtained using the dpkg program: dpkg --get-selections

The --get-selections option is needlessly verbose, there is no shorter version of it and it is hard to recall.

A better option is to use: dpkg -l

This lists other details of the package along with its name, like version, architecture and description. But hey, the option is easier to recall 😊

Tried with: Dpkg 1.17.5 and Ubuntu 14.04
