You could use '--prune-empty-dirs' with rsync.

No, but it supports '-depth', which means you can

 	find /mnt/jaguar/users/michelle/FlacCopy -depth -type d \
 		-exec rmdir {} \; 2>/dev/null

That will fail *a lot*, but the error messages are thrown away and the
empty directories will be deleted.

or if you have GNU fileutils installed (so 'grmdir' exists)

 	find /mnt/jaguar/users/michelle/FlacCopy -depth -type d \
 		-exec grmdir --ignore-fail-on-non-empty {} \;

-depth is important for either of these to work.

The best part of both of those is that you can insert 'echo' between
'-exec' and the start of the command, and it will show you what it's
going to do without doing it.  If you like what you see, just remove the
'echo'.

Someone else already answered with the correct pkg FMRI.
