As `man test' describes, the /bin/test executable does not
recognize a == operator.
Neither in `sh' nor in `bash' the `test' executable will be called
(unless written as /bin/test). In both cases it is a builtin
command. The Sh builtin works like the `test' executable; the Bash
builtin recognizes ==.
