    NAME

    od - dump files in octal and other formats
     
    

    SYNOPSIS

    od [OPTION]... [FILE]...
    od [-abcdfilosx]... [FILE] [[+]OFFSET[.][b]]
    od --traditional [OPTION]... [FILE] [[+]OFFSET[.][b] [+][LABEL][.][b]]  

    DESCRIPTION

    Write an unambiguous representation, octal bytes by default, of FILE to standard output. With more than one FILE argument, concatenate them in the listed order to form the input. With no FILE, or when FILE is -, read standard input.

    All arguments to long options are mandatory for short options.

    -A, --address-radix=RADIX
    decide how file offsets are printed
    -j, --skip-bytes=BYTES
    skip BYTES input bytes first
    -N, --read-bytes=BYTES
    limit dump to BYTES input bytes
    -S, --strings[=BYTES]
    output strings of at least BYTES graphic chars
    -t, --format=TYPE
    select output format or formats
    -v, --output-duplicates
    do not use * to mark line suppression
    -w, --width[=BYTES]
    output BYTES bytes per output line
    --traditional
    accept arguments in traditional form
    --help
    display this help and exit
    --version
    output version information and exit
     

    Traditional format specifications may be intermixed; they accumulate:

    -a
    same as -t a, select named characters
    -b
    same as -t o1, select octal bytes
    -c
    same as -t c, select ASCII characters or backslash escapes
    -d
    same as -t u2, select unsigned decimal 2-byte units
    -f
    same as -t fF, select floats
    -i
    same as -t dI, select decimal ints
    -l
    same as -t dL, select decimal longs
    -o
    same as -t o2, select octal 2-byte units
    -s
    same as -t d2, select decimal 2-byte units
    -x
    same as -t x2, select hexadecimal 2-byte units

    If first and second call formats both apply, the second format is assumed if the last operand begins with + or (if there are 2 operands) a digit. An OFFSET operand means -j OFFSET. LABEL is the pseudo-address at first byte printed, incremented when dump is progressing. For OFFSET and LABEL, a 0x or 0X prefix indicates hexadecimal; suffixes may be . for octal and b for multiply by 512.

    TYPE is made up of one or more of these specifications:

    a
    named character
    c
    ASCII character or backslash escape
    d[SIZE]
    signed decimal, SIZE bytes per integer
    f[SIZE]
    floating point, SIZE bytes per integer
    o[SIZE]
    octal, SIZE bytes per integer
    u[SIZE]
    unsigned decimal, SIZE bytes per integer
    x[SIZE]
    hexadecimal, SIZE bytes per integer

    SIZE is a number. For TYPE in doux, SIZE may also be C for sizeof(char), S for sizeof(short), I for sizeof(int) or L for sizeof(long). If TYPE is f, SIZE may also be F for sizeof(float), D for sizeof(double) or L for sizeof(long double).

    RADIX is d for decimal, o for octal, x for hexadecimal or n for none. BYTES is hexadecimal with 0x or 0X prefix, it is multiplied by 512 with b suffix, by 1024 with k and by 1048576 with m. Adding a z suffix to any type adds a display of printable characters to the end of each line of output. --string without a number implies 3. --width without a number implies 32. By default, od uses -A o -t d2 -w 16.
