  Hi Bear,
    Your example works fine as I already know, but your example does not
duplicate the syntax of my original question.   What you did was back up
an entire directory, which I have no trouble with either.
Try this instead:

cd into a directory of your choice.
pick some file you don't care about, maybe a *.bak or whatever.
Now, using find, pipe that file into cpio so it archives it into your
archive file called "foo".
Try that and see how it works.  Once again, I can't find the correct
cpio syntax to append a file to a single archive file.

 cpio created the file, not me...
