Anybody who dislikes the way his Unix works is at liberty to "roll his 
own".  "Unix" is a catch-all for a bunch of operating systems even 
though it's *legally* somebody's "Registered Trade Mark".

Kernigan and Ritchie wrote the original.  The Comp. Sci. students at 
University of California Berkeley expanded it, "prettied" it up a bit 
and added some ugly bits of their own!  People have been tinkering with 
it for the last forty years or more.

There are several implementations of Unix.  Some called "Unix" and
some versions with their own Trade Mark.   Functionality is similar
but pieces of "Brand-X" will not necessarily be compatible with "Brand-Y".

There IS a standard for Unix but there are a lot of people who wanted to 
do it "their way" and made it so.
