Say I have a directory named foo/. This folder includes subdirectories. How can I delete all the empty directories in one command?
Try this command:
find . -empty -type d -delete
The find command is used to search for files/directories matching a particular search criteria from the specified path, in this case the current directory (hence the .).
The -empty option holds true for any file and directory that is empty.
The -type d option holds true for the file type specified; in this case d stands for the file type directory.
The -delete option is the action to perform, and holds true for all files found in the search.
