You might try tar(1), however you will have to fix it. If you have source
that is. As in the example in the manual type:

	cd fromdir; tar cf - . | ( cd todir; tar xf - )

The problem with this is that when tar tries to make a directory in todir
it execs mkdir(1), then waits for ALL of its children to complete. But in
the bourne shell the first tar is a child of the second tar, so it can hang
forever. All you have to do is fix tar(1) so it only waits for the process
that it forked.

System V, a standard to live down to. :-)
