On Windows for years I was using a program called CCleaner. It removed old or unused files, did some stuff to the registry and so force. I don’t think much of it actually improved anything but I just got used to running that and then I felt like the system was clean and smooth after. Placebo effect I suppose.
Is there anything like this for Linux. Or if I remove software from the terminal or the Add/Remove Programs am I safe to assume its removed everything and its clean?
I would like to be able to get that feeling again though. Ideas/suggestions.
