Thanks Peter.  BTW, the contents of the /help directory, I never been 
able to figure out how one accesses that information, it seems that it 
is meant to be pulled up by some command.  'run-help' doesn't do it, 
'man' neither.  For example 'test' contains:

test [ arg ... ]
[ [ arg ... ] ]
        Like the system version of test.  Added for  compatibility; use
        conditional  expressions  instead  (see the section `Conditional
        Expressions').  The main  differences  between  the conditional
        expression  syntax  and the test and [ builtins are:  these com-
        mands are not handled syntactically, so  for  example  an empty
        variable  expansion  may cause an argument to be omitted; syntax
        errors cause status 2 to be returned instead of a  shell error;
        and  arithmetic  operators  expect integer arguments rather than
        arithmetic expressions.

        The command attempts to implement POSIX and its extensions where
        these are specified.  Unfortunately there are intrinsic ambigui-
        ties in the  syntax;  in  particular  there  is  no distinction
        between  test  operators  and  strings  that resemble them. The
        standard attempts to resolve these for small  numbers  of argu-
        ments  (up  to  four);  for five or more arguments compatibility
        cannot be relied on.  Users are urged wherever possible  to use
        the `[[' test syntax which does not have these ambiguities.

... and that's possibly useful help, but how do I get to it?
