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.
this is not really what the article is about.
yes you can read man page, you can find there all possible locations of config files. yet you still don’t know where config file is stored. you have to check all the possible locations.
also if there would be some standard so you can query app for its config files, you could make automated backups easily. at least much easier that now.
of course I understand this is completely unrealistic, in software world everyone will do whatever they want…
