That's fine for some things, but consider two directories that
are very similar, and you want to find which files are in dir2
that aren't in dir1.

	cd dir1
	find . -type f | sort > /tmp/list1
	cd dir2
	find . -type f | sort > /tmp/list2
	comm -13 /tmp/list1 /tmp/list2 > /tmp/list3

Now /tmp/list3 has a list of all files in dir2 that aren't in dir1.
Perhaps you want to copy all the files from dir2 that aren't in
dir1, now you can run:

	cpio -pdumv dir1 < /tmp/list3
