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.
All arguments to long options are mandatory for short options.
−A, −−address−radix=RADIXdecide how file offsets are printed
−j, −−skip−bytes=BYTESskip BYTES input bytes first
−N, −−read−bytes=BYTESlimit dump to BYTES input bytes
−S, −−strings[=BYTES]output strings of at least BYTES graphic chars
−t, −−format=TYPEselect output format or formats
−v, −−output−duplicatesdo not use * to mark line suppression
−w, −−width[=BYTES]output BYTES bytes per output line
−−traditionalaccept arguments in traditional form
−−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 ASCII characters or backslash escapes
−dsame as −t u2,
select unsigned decimal 2−byte units
−fsame as −t fF,
select floats
−isame as −t dI,
select decimal ints
−lsame as −t dL,
select decimal longs
−osame as −t o2,
select octal 2−byte units
−ssame as −t d2,
select decimal 2−byte units
−xsame 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:
anamed character, ignoring high−order bit
cASCII character or backslash escape
signed decimal, SIZE bytes per integer
floating point, SIZE bytes per integer
octal, SIZE bytes per integer
unsigned decimal, SIZE bytes per integer
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,
and may have a multiplier suffix: b 512, kB 1000, K 1024,
MB 1000*1000, M 1024*1024, GB 1000*1000*1000, G
1024*1024*1024, and so on for T, P, E, Z, Y. Adding a z
suffix to any type displays printable characters at the end
of each output line. −−string without a number
implies 3. −−width
without a number implies 32. By default, od uses
−A o −t d2 −w16.
