Check For Empty Directories Using ‘find’ Shell Command

find /path/to/directory -type d -empty -exec echo {} ;

I think it’s easy to get the idea based on the example above, but just in case you need inspiration, you could automatically remove these empty directories with the following (Careful! This uses ‘-rf’ flag which shows no warnings or mercy!):

find /path/to/directory -type d -empty -exec rm -rf {} ;
