cp is a command to copy a file. Files can be copied either to the same directory or to a completely different directory, possibly on a different file system or hard disk drive. If the file is copied to the same directory, the new file must have a different name to the original; in all other cases, the new file may have the same or a different name. The original file remains unchanged.
