I wholeheartedly agree with this blog post. I believe someone on here yesterday was asking about config file locations and setting them manually. This is in the same vein. I can’t tell you how many times a command line method for discovering the location of a config file would have saved me 30 minutes of googling.
~/.localis the non-root version of/usr. By.appnamedo you just mean a folder that a specific app made in your home for itself? Yeah, I never condone that. imo that’s just a badly behaving app. It should move that folder into~/.config.
