The implications are precisely what you suppose they’re, and that’s the reason anybody who cares for safety should use do-it-yourself casing for one thing critical or in any respect.

Then it will likely be executed as an alternative of the system binary everytime you write this system with the identical title on the command line (except you write the whole route).
