Параметры (Options)

The od utility shall conform to the Base Definitions volume of
       POSIX.1‐2017, Section 12.2, Utility Syntax Guidelines, except
       that the order of presentation of the -t options and the -bcdosx
       options is significant.

       The following options shall be supported:

       -A address_base
                 Specify the input offset base. See the EXTENDED
                 DESCRIPTION section.  The application shall ensure that
                 the address_base option-argument is a character. The
                 characters 'd', 'o', and 'x' specify that the offset
                 base shall be written in decimal, octal, or
                 hexadecimal, respectively. The character 'n' specifies
                 that the offset shall not be written.

       -b        Interpret bytes in octal. This shall be equivalent to
                 -t o1.

       -c        Interpret bytes as characters specified by the current
                 setting of the LC_CTYPE category. Certain non-graphic
                 characters appear as C escapes: "NUL=\0", "BS=\b",
                 "FF=\f", "NL=\n", "CR=\r", "HT=\t"; others appear as
                 3-digit octal numbers.

       -d        Interpret words (two-byte units) in unsigned decimal.
                 This shall be equivalent to -t u2.

       -j skip   Jump over skip bytes from the beginning of the input.
                 The od utility shall read or seek past the first skip
                 bytes in the concatenated input files. If the combined
                 input is not at least skip bytes long, the od utility
                 shall write a diagnostic message to standard error and
                 exit with a non-zero exit status.

                 By default, the skip option-argument shall be
                 interpreted as a decimal number. With a leading 0x or
                 0X, the offset shall be interpreted as a hexadecimal
                 number; otherwise, with a leading '0', the offset shall
                 be interpreted as an octal number. Appending the
                 character 'b', 'k', or 'm' to offset shall cause it to
                 be interpreted as a multiple of 512, 1024, or 1048576
                 bytes, respectively. If the skip number is hexadecimal,
                 any appended 'b' shall be considered to be the final
                 hexadecimal digit.

       -N count  Format no more than count bytes of input. By default,
                 count shall be interpreted as a decimal number. With a
                 leading 0x or 0X, count shall be interpreted as a
                 hexadecimal number; otherwise, with a leading '0', it
                 shall be interpreted as an octal number. If count bytes
                 of input (after successfully skipping, if -j skip is
                 specified) are not available, it shall not be
                 considered an error; the od utility shall format the
                 input that is available.

       -o        Interpret words (two-byte units) in octal. This shall
                 be equivalent to -t o2.

       -s        Interpret words (two-byte units) in signed decimal.
                 This shall be equivalent to -t d2.

       -t type_string
                 Specify one or more output types. See the EXTENDED
                 DESCRIPTION section. The application shall ensure that
                 the type_string option-argument is a string specifying
                 the types to be used when writing the input data. The
                 string shall consist of the type specification
                 characters a, c, d, f, o, u, and x, specifying named
                 character, character, signed decimal, floating point,
                 octal, unsigned decimal, and hexadecimal, respectively.
                 The type specification characters d, f, o, u, and x can
                 be followed by an optional unsigned decimal integer
                 that specifies the number of bytes to be transformed by
                 each instance of the output type. The type
                 specification character f can be followed by an
                 optional F, D, or L indicating that the conversion
                 should be applied to an item of type float, double, or
                 long double, respectively. The type specification
                 characters d, o, u, and x can be followed by an
                 optional C, S, I, or L indicating that the conversion
                 should be applied to an item of type char, short, int,
                 or long, respectively. Multiple types can be
                 concatenated within the same type_string and multiple
                 -t options can be specified. Output lines shall be
                 written for each type specified in the order in which
                 the type specification characters are specified.

       -v        Write all input data. Without the -v option, any number
                 of groups of output lines, which would be identical to
                 the immediately preceding group of output lines (except
                 for the byte offsets), shall be replaced with a line
                 containing only an <asterisk> ('*').

       -x        Interpret words (two-byte units) in hexadecimal. This
                 shall be equivalent to -t x2.

       Multiple types can be specified by using multiple -bcdostx
       options. Output lines are written for each type specified in the
       order in which the types are specified.
