I'm not getting how this section of code could ever be made. 1. Why do we search for a file or directory, when we have an if-clause on top, which already checks for it? Searching for something that has already been found is pointless. 2. Why is there a search for a file (that is the bug I'm actually running into here), if we already know the path is a file type of data? It's like checking for something and knowing already it will fail. When thinking of the name of the environment variable, I think only the directory check is necessary, but someone added the "-f" check. Maybe to test for symlinks? (It would be normally done via "-L" if I'm not wrong, but "-f" catches them, too.) For the reason of knowing to less of the history of this section, I'm keeping as much logic as possible.
