In fact it's impossible for an unprivileged user process running on a properly configured UNIX system, except by very special arrangement that is simply not relevant for this discussion. (Privileged processes can do just about anything at all, and cooperating processes can have a parent modify the environment based on requests from a child process. Neither of these situations holds for normal UNIX programs.)
