Which command allows you to copy files and directories recursively?

The command that allows you to copy files and directories recursively is represented by both the lowercase "r" and the uppercase "R." Using either the "cp -r" or "cp -R" option with the cp command will enable you to copy entire directories along with their contents, including subdirectories and files within those directories.

The recursive option is essential when you want to ensure that the entire directory structure is replicated in the destination you specify. The "-r" option is widely used and is the more common way to invoke recursive copying, while the "-R" option serves the same purpose and is also accepted by the cp command to perform recursive copies.

Choosing both "cp -r" and "cp -R" as valid solutions emphasizes that the command is flexible, allowing users to use either case for recursive operations. This feature enhances usability, particularly for those who might be typing commands quickly or have differing preferences for case sensitivity in terminal commands.
