Which command is used to copy files recursively in Linux?

The command used to copy files recursively in Linux is the "cp" command with the -r or --recursive option. This allows users to copy entire directories along with all of their contents—not just individual files—ensuring that subdirectories and their files are also included.

When used correctly, "cp -r source_directory destination_directory" will create a copy of the source directory and all of its files and subdirectories in the specified destination. The ability to handle directories and files in this manner is a fundamental feature of the "cp" command, making it essential for tasks involving file management in Linux systems.

The other options listed do not provide the functionality required for recursively copying files and directories in a Linux environment. "copy" is not a standard Linux command; it's more commonly associated with DOS or Windows environments. "xcopy" is specific to Windows and is used for copying files and directories but is not relevant to Linux. "mv" is a command used to move files or directories from one location to another, rather than copying them.
