The words usually, and should are the kickers. In the 24 years I've been making my living on various versions of Unix type systems, I've seen a lot of cases where this type of assumption either fails totally or gets me in trouble because the vendor didn't do it the way they should. This is the reason I started building standard open source tools for all the systems we support (Richard Stallman would probably have said I was creating GNU/Xenix and GNU/OpenServer systems back when we supported many SCO systems :-). My fingers automatically type gfind, gdu, etc., even on Linux systems where I make symbolic links as necessary so I don't have to remember what type of system I'm typing on. One of the basic tenets of the *nix philosophy is ``build on the work of others'', and it's a lot easier to leave figuring out the guts of various systems to the authors of the gnu fileutils than it is to reinvent their work every time I want to do something.
