od — dump files in octal and other formats
od [OPTION...] [FILE...]
od [−abcdfilosx...] [FILE] [[+]OFFSET[.][b]]
od −−traditional [OPTION...] [FILE] [ [+]OFFSET[.][b] [+][LABEL][.][b] ]
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.
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.
Mandatory arguments to long options are mandatory for short options too.
−A, −−address−radix=RADIXoutput format for file offsets; RADIX is one of [doxn], for Decimal, Octal, Hex or None
−−endian={big|little}swap input bytes according the specified order
−j, −−skip−bytes=BYTESskip BYTES input bytes first
−N, −−read−bytes=BYTESlimit dump to BYTES input bytes
−S BYTES, −−strings[=BYTES]output strings of at least BYTES graphic chars; 3 is implied when BYTES is not specified
−t, −−format=TYPEselect output format or formats
−v, −−output−duplicatesdo not use * to mark line suppression
−w[BYTES], −−width[=BYTES]output BYTES bytes per output line; 32 is implied when BYTES is not specified
−−traditionalaccept arguments in third form above
−−helpdisplay this help and exit
−−versionoutput version information and exit
−asame as −t a,
select named characters, ignoring high−order
bit
−bsame as −t o1,
select octal bytes
−csame as −t c,
select printable characters or backslash escapes
−dsame as −t u2,

−fsame as −t fF,

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).
Adding a z suffix to any type displays printable characters at the end of each output line.
