What does the 'ls -R' command do?

The command 'ls -R' is used in Unix and Linux operating systems to display the contents of directories and subdirectories in a recursive manner. This means it lists all files and folders within the current directory and continues to delve into each subdirectory, showcasing their contents as well.

When used, 'ls -R' allows users to view the entire directory hierarchy starting from the current directory, making it particularly useful for understanding the structure of complex directories or verifying the presence of specific files across multiple levels.

This command enhances typical file listing by not just stopping at the immediate contents of a folder, but rather providing a comprehensive overview of everything stored within nested directories. This capability distinguishes it from commands that only list files in the current location or perform searches, as it offers a complete snapshot of the directory tree.
