agree with rsync, though : find <SRC> -print | cpio -pdvm NEWPATH ;
would copy <SRC> directory to <NEWPATH>/<SRC>, I'd stick to rsync as
cpio would skip existing files too but would not deal very well with
files that did not finish copying due to an interruption.
as far as deleting any empty directory, I'd would run a search and
pipe the output to rmdir, rmdir would only delete the directory if it
is empty, but
DO NOT USE rm -R
find <SRC> -type d -print | xargs rmdir
the only problem with this approach is that if you have
<PATH>/dir1/dir2/dir3 and no other files, then you would still end up
with dir1/dir2 directories
hope it helps.
