It does work: it just probably doesn't do what you want or expect it to.
(You don't give any details of your problem, so I'm guessing here, but
you aren't the first or the last with such a complaint.)

If you specify wildcards on the command line, these wildcards are
expanded by your shell (or on Windows by a library loaded with 'grep').
Grep itself never sees them, and does not apply them to directories
it encounters.  As a consequence, all the files descended from any
directory arguments (whether specified with wildcards or not) are grepped.

If this is *not* your problem, please try us again.

[T]here is a Darwinian explanation for the refusal to accept Darwin.
Given the very pessimistic conclusions about moral purpose to which his
theory drives us, and given the importance of a sense of moral purpose
in helping us cope with life, a refusal to believe Darwin's theory may
have important survival value. --Ian Johnston
