MAN PAGES: UNSET COMMAND
Each name shall be unset.
the shell shall unset it
and remove it from the environment.
Unsetting shall not be considered an error.
The unset shall support the Base Definitions.
Note that unset should not be
misinterpreted.
Unset the functions
favor the standard
retain historical practice.
The System used one name
without options
and there was no confusion.
