I was wondering How one can list (or if there is an online list) of most important/popular (alternatively all) default installed programs/packages in ubuntu? I know how to list packages, but many I don't know what they do.
Something like this, but for the actually installed system (in my case 13.10): https://help.ubuntu.com/community/ListOfOpenSourcePrograms
Is it possible to generate, of course maybe not by category?
thanks! T
