cmp¶

compare two files byte for byte
NAME
    cmp - compare two files byte for byte

SYNOPSIS
    cmp file1 file2

DESCRIPTION
    Compares the two files. If they are identical, cmp prints nothing and
    succeeds. Otherwise it reports where they first differ:

        cmp: files differ: byte N, line M

    (N and M are 1-based). If one file is a prefix of the other -- equal up to
    the shorter one's end -- cmp names the file that ended first:

        cmp: EOF on file1        (file2 is longer)
        cmp: EOF on file2        (file1 is longer)

    The first file is read into memory (up to 8 KB) and the second is streamed
    and compared against it. A byte-level companion to diff (which compares by
    line). cmp is a /bin program.

EXAMPLES
    cmp a.bin b.bin        silent if identical; else the first differing byte
    cmp old.txt new.txt    "byte N, line M" of the first difference
