Linux - Find - Find Empty Directories

find ./ -type d -empty

This command will find all empty directories in the current directory with sub-directories and then print the full pathname for each empty directory to the screen.

• ./ means start searching from the current directory. If you want to find files from another directory then replace the ./ with the path to needed directory. For example, to search everything under the system log directory you need to replace ./ with /var/log.
• -type d flag is specifies to find only directories.
• -empty flag is specifies to find empty directories.

To find and then delete all empty directories, use:

find ./ -depth -type d -empty -exec rmdir {} \;

or

find ./ -type d -empty -delete
