[MATLAB] copyfile 파일복사하기

input.txt를 output.txt 로 통채로 카피하고 싶을때  

(파일의 종류는 무엇이 되든 상관없음. 사진이든 뭐든 상관없음))

copyfile('input.txt','output.txt');

주의, copyfile의 두 인자는 파일의 이름 (m파일과 같은 폴더에 있는 경우) 

       혹은 주소를 넣어주어야 한다.

COPYFILE   Copy file or directory.

    [SUCCESS,MESSAGE,MESSAGEID] = COPYFILE(SOURCE,DESTINATION,MODE) copies

    the file or directory SOURCE to the new file or directory DESTINATION.

    Both SOURCE and DESTINATION may be either an absolute pathname or a

    pathname relative to the current directory. When the MODE is set to

    'f', COPYFILE copies SOURCE to DESTINATION, even when DESTINATION is

    read-only. The DESTINATION's writable attribute state is preserved. 

 

    [SUCCESS,MESSAGE,MESSAGEID] = COPYFILE(SOURCE) attempts to copy SOURCE

    to the current directory.

 

    [SUCCESS,MESSAGE,MESSAGEID] = COPYFILE(SOURCE, DESTINATION) attempts to

    copy SOURCE to DESTINATION. If SOURCE constitutes a directory or

    multiple files and DESTINATION does not exist, COPYFILE attempts to

    create DESTINATION as a directory and copy SOURCE to DESTINATION. If

    SOURCE constitutes a directory or multiple files and DESTINATION exists

    as a directory, COPYFILE attempts to copy SOURCE to DESTINATION. If

    SOURCE constitutes a directory or multiple files and none of the above

    cases on DESTINATION applies, COPYFILE fails.

 

    [SUCCESS,MESSAGE,MESSAGEID] = COPYFILE(SOURCE,DESTINATION,'f') attempts

    to copy SOURCE to DESTINATION, as above, even if DESTINATION is

    read-only. The status of the writable attribute of DESTINATION will be

    preserved.

 

    INPUT PARAMETERS:

        SOURCE:      1 x n string, defining the source file or directory.

        DESTINATION: 1 x n string, defining destination file or directory.

                     The default is the current directory. 

        MODE:        character scalar defining copy mode.

                     'f' : force SOURCE to be written to DESTINATION. If

                     omitted, COPYFILE respects the current writable status

                     of DESTINATION. 

 

    RETURN PARAMETERS:

        SUCCESS:     logical scalar, defining the outcome of COPYFILE.

                     1 : COPYFILE executed successfully. 0 : an error

                     occurred.

        MESSAGE:     string, defining the error or warning message.

                     empty string : COPYFILE executed successfully. message

                     : an error or warning message, as applicable.

        MESSAGEID:   string, defining the error or warning identifier.

                     empty string : COPYFILE executed successfully. message

                     id: the MATLAB error or warning message identifier

                     (see ERROR, MException, WARNING, LASTWARN).

 

    NOTE 1: Except where otherwise stated, the rules of

            the underlying system on the preservation of attributes are

            followed when copying files and directories.

    NOTE 2: The * wildcard is supported in the filename or extension.

 

    See also cd, delete, dir, fileattrib, mkdir, movefile, rmdir.
