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.
If it’s not in /etc it should be in the directory the exe file is located.
Certainly not. Nothing should write to /usr/bin except for the package manager in FHS distros and some distros binary directories aren’t writable at all.
Well good because a program shouldn’t be writing to its config file either.
