When I go to the Ubuntu Software Center and click on Installed, I get a categorized list of all applications. It's something for example like Accessories (Disk, Text editor, ...), Developer tools (Printers, OpenJDK Java, ...), Games Graphics (SignPost, AisleRiot, ...), ... and so on.
I'd like to have the same list in a textual form in a file. Something like the example above.
apt-cache show zim
