And I need to delete/uninstall a program (I know, this is too basic), and I would like to delete everything related to the program/application. That is, program, configuration files, etc.
So:
R = remove program/application
n = remove configuration files
s = remove dependencies
Is there any other letter that you recommend I add when uninstalling an application?
That command removes the package and its un-needed dependencies. The configuration files (the stuff in .config) and also local program data (~/.local/share) will not be removed.
So how do I remove all of that, with another terminal command, or by carefully going into those 2 folders and removing anything related to this program?
