Overview

Dump files in octal and other formats

Options

--help: Print help information.

-A, --address-radix <RADIX>: Select the base in which file offsets are printed.

-j, --skip-bytes <BYTES>: Skip bytes input bytes before formatting and writing.

-N, --read-bytes <BYTES>: limit dump to BYTES input bytes

--endian <big|little>

byte order to use for multi-byte formats

Possible values:

•: big

•: little

-S, --strings [<BYTES>]: output strings of at least BYTES graphic chars. 3 is assumed when BYTES is not specified.

-a: named characters, ignoring high-order bit

-b: octal bytes

-c: ASCII characters or backslash escapes

-d: unsigned decimal 2-byte units

-D: unsigned decimal 4-byte units

-o: octal 2-byte units

-I: decimal 8-byte units

-L: decimal 8-byte units

-i: decimal 4-byte units

-l: decimal 8-byte units

-x: hexadecimal 2-byte units

-h: hexadecimal 2-byte units

-O: octal 4-byte units

-s: decimal 2-byte units

-X: hexadecimal 4-byte units

-H: hexadecimal 4-byte units

-e: floating point double precision (64-bit) units

-f: floating point single precision (32-bit) units

-F: floating point double precision (64-bit) units

-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. 32 is implied when BYTES is not specified.

--traditional: compatibility mode with one input, offset and label.

-V, --version: Print version

Extra

Displays data in various human-readable formats. If multiple formats are specified, the output will contain all formats in the order they appear on the command line. Each format will be printed on a new line. Only the line containing the first format will be prefixed with the offset.

If no filename is specified, or it is "-", stdin will be used. After a "--", no more options will be recognized. This allows for filenames starting with a "-".

If a filename is a valid number which can be used as an offset in the second form, you can force it to be recognized as a filename if you include an option like "-j0", which is only valid in the first form.

RADIX is one of o,d,x,n for octal, decimal, hexadecimal or none.

BYTES is decimal by default, octal if prefixed with a "0", or hexadecimal if prefixed with "0x". The suffixes b, KB, K, MB, M, GB, G, will multiply the number with 512, 1000, 1024, 1000^2, 1024^2, 1000^3, 1024^3, 1000^2, 1024^2.

OFFSET and LABEL are octal by default, hexadecimal if prefixed with "0x" or decimal if a "." suffix is added. The "b" suffix will multiply with 512.

TYPE contains one or more format specifications consisting of:
a for printable 7-bits ASCII
c for utf-8 characters or octal for undefined characters
d[SIZE] for signed decimal
f[SIZE] for floating point
o[SIZE] for octal
u[SIZE] for unsigned decimal
x[SIZE] for hexadecimal SIZE is the number of bytes which can be the number 1, 2, 4, 8 or 16,
or C, S, I, L for 1, 2, 4, 8 bytes for integer types,
or F, D, L for 4, 8, 16 bytes for floating point. Any type specification can have a "z" suffix, which will add a ASCII dump at
the end of the line.

If an error occurred, a diagnostic message will be printed to stderr, and the exit code will be non-zero.
