How to see all installed applications

Question

I am using Ubuntu 14.10 default GUI, how can I see all the applications installed ? if I don't give a search keyword I can't see anything.

Answer 1

In the terminal you can see a list of all installed packages like this:

dpkg -l

Or, for example, write listing to a file:

dpkg -l > packages.txt

Answer 2

Personally I use terminal commands dpkg --get-selections | less or dpkg --get-selections | grep packagename
