Explanation

The man (manual) command in UNIX displays documentation for commands, so 'man cp' shows the cp command's manual page with usage syntax, options, and examples. The 'help' command works for shell built-ins, not external commands like cp. The '?' syntax is used in different systems but not standard UNIX.
