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.
The XDG Base Directory standard has kinda sorta been doing that; and I like it. Not everything supports it; and it’s not perfect, but at least it’s better than the wild west that application configs used to be.
