    cksum

    I've been read an article describe cksum, like this
    'cksum computes a cyclic redundancy check (CRC) checksum for each given file, or standard input'.
    and also about one char is one byte.
    But when execute cksum like this
    Code:
    echo are | cksum
    and the output
    Code:
    2979220839 4
    why output is 4, I think 'are' have 3 byte.

    Hi.
    Code:
    % echo are | od -bc
0000000 141 162 145 012
          a   r   e  \n
    The newline character (LF, linefeed, 12b) is added to the string by echo ... cheers, drl

    Oh my God, I forgot you "newline".
    Yeah its great newline has been added by echo, and when i use -n option in echo, the output is 3.
    Thankyou very much.
