How can I find which applications are installed on my system?

Question

Is it possible to get a list of the applications which have been installed?

I'm using ubuntu 12.04.

Open up the Ubuntu Software Centre. Click on the button labelled "Installed". All the apps installed will be listed under their respective categories.

A command line alternative is to use

$ sudo dpkg --get-selections

Just press the Super key (Windows flag key) and goto application lens (on the bottom). Click installed and there you go.

or by synaptic,

sudo apt-get install synaptic
