Well, you guys are the experts. I was trying to be "smart" - thinking that lbracket 'required' the closing right bracket to keep the shell syntax checkers happy. Maybe I am expecting too much from my shells need to check syntax.

FYI - It seems to be working as expected, rather designed - so I shall make some specialized 'buildaix' components to get around the filenameing problem.

Will keep you posted.

Rather, the 'test' binary and the 'lbracket' binary differ in one
crucial aspect: 'lbracket' requires its last argument in argv[] to be
"]". It is not ksh, but lbracket itself that requires the matching ],
and it is this fact that allows us to obey POSIX while still allowing '[
--help' to produce help text, even though 'test --help' cannot do so
(that is, '[' has an escape hatch that 'test' does not).
