Re: joining and extracting archive

It should work.  Try maybe giving the -c explicitly to gzip.
I don't think there are any problems with the shell that would
affect it.  Maybe do a cmp between the pipe and the result of
combining them, to make sure that isn't the problem.  But I'm
not sure what wouldn't work, it looks good to me.  -Tom
