5.4 Listing Directory Contents
5.4.6 Listing directories recursively
Use ls -R (recursive) to display the contents of a directory and all of its subdirectories. Recursive means to do again and again. This option is useful if you want to see all directories, subdirectories and their contents for a particular part of the directory tree. If this is done at a high level in the directory structure, the output can be substantial. 

Note: The -R option is an upper case R.

The R (or sometimes r) option is commonly used with many UNIX commands to indicate a recursive action. Recursive generally refers to the contents of a directory and all of its subdirectories.
