Shouldn't that be
instead?  At first I thought you had been overzeaulous in protecting
the * from the shell by escaping it with a backslash, but then I
realized you must have been thinking like a Windows user instead.
Well, if you really were thinking of escaping it, maybe you were
thinking like a csh user.  But the Bourne shell does not expand
wildcards in variables the way csh does.

FWIW, the version of unzip that I have does not support this exclusion
option.  The manual page for the unzip I have here says

       -x  extract files in archive (default)

So, unless you distribute your own version of unzip, I doubt there is
a portable way to achieve what you want to do.  The usual solution on
Unix systems is to use compressed tar files instead.
