FYI: the list of files/dirs to be copied can be in a file too. Allows
utils like comm or diff to be used for various paring/augmenting

No need for the pipe/sub-shell with cpio. It is fully featured.

However, with "fully featured" comes the need to RTFM and carefully

    find . | cpio -p<other options> <destination-dir>
