Recursive

In linux, recursive is a feature/option used in rm command.When rm command is used with the option –r, removes the directory recursively. "Recursive" implies that the operation will be performed for all files and directories.Recursive means that cp copies the contents of directories, and if a directory has subdirectories they are copied (recursively) too. Without -R , the cp command skips directories. -r is identical with -R on Linux, it differs in some edge cases on some other unix variants.
