    cmp - compare two files

    c\bcm\bmp\bp [ -\b-l\bl ] [ -\b-s\bs ] file1 file2 [ skip1 ] [ skip2 ]

    The two files are compared.  (If _\bf_\bi_\bl_\be_\b1 is `-', the standard
    input is used.)  With no options, _\bc_\bm_\bp makes no comment if
    the files are the same; if they differ, it reports the byte
    and line number at which the difference occurred, or, that
    one file is an initial subsequence of the other.  _\bS_\bk_\bi_\bp_\b1 and
    _\bs_\bk_\bi_\bp_\b2 are initial byte offsets into _\bf_\bi_\bl_\be_\b1 and _\bf_\bi_\bl_\be_\b2 respec-
    tively, and may be either octal or decimal; a leading ``0''
    denotes octal.

    Options:

    -\b-s\bs    Print nothing for differing files; set exit codes
          only.

    -\b-l\bl    Print the byte number (in decimal) and the differing
          bytes (in octal) for all differences between the two
          files.

S\bSE\bEE\bE A\bAL\bLS\bSO\bO
    diff(1), comm(1)

D\bDI\bIA\bAG\bGN\bNO\bOS\bST\bTI\bIC\bCS\bS
    Exit code 0 is returned for identical files, 1 for different
    files, and 2 for an inaccessible or missing argument, or a
    system error.
