Well, there is no native command (at least, afaik), but you can use find to easily identify empty folders (which maybe helpful for maintenance, etc.):

# find /path -type d -empty

Find empty folder and list

# find /path -type d -empty -exec ls -ld {} \;

Find empty folder and save as temporary file

# find /path -type d -empty -exec ls -ld >> /tmp/savefiles.txt {} \;

Find empty folder and delete

# find /path -type d -empty -exec rmdir {} \;
