There is a real easy simple way to view all the applications you have installed on your Mac from the command line. Load Terminal and type the following command
This will show you all the applications, you can also send this into a text file so you can review this later
ls /Applications > /tmp/applist.txt
You can also see what applications have been recently updated, by typing
ls -ltr /Applications
