The command is also available in the EFI shell. GNU cp has many additional options over the POSIX version. The two major specifications are POSIX cp and GNU cp. The utility further accepts various command line option flags to detail the operations performed. The command has three principal modes of operation, expressed by the types of arguments presented to the program for copying a file to another file, one or more files to a directory, or for copying entire directories to another directory.
