NAME

6       od - dump files in octal and other formats
7

SYNOPSIS

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

DESCRIPTION

14       Write an unambiguous representation, octal bytes by default, of FILE to
15       standard output.  With more than one FILE argument, concatenate them in
16       the listed order to form the input.
17
18       With no FILE, or when FILE is -, read standard input.
19
20       If  first  and  second  call  formats  both apply, the second format is
21       assumed if the last operand begins with + or (if there are 2  operands)
22       a   digit.    An   OFFSET  operand  means  -j  OFFSET.   LABEL  is  the
23       pseudo-address at first byte printed, incremented  when  dump  is  pro‐
24       gressing.   For OFFSET and LABEL, a 0x or 0X prefix indicates hexadeci‐
25       mal; suffixes may be . for octal and b for multiply by 512.
26
27       Mandatory arguments to long options are  mandatory  for  short  options
28       too.
29
30       -A, --address-radix=RADIX
31              output format for file offsets; RADIX is one of [doxn], for Dec‐
32              imal, Octal, Hex or None
33
34       --endian={big|little}
35              swap input bytes according the specified order
36
37       -j, --skip-bytes=BYTES
38              skip BYTES input bytes first
39
40       -N, --read-bytes=BYTES
41              limit dump to BYTES input bytes
42
43       -S BYTES, --strings[=BYTES]
44              output strings of at least BYTES graphic  chars;  3  is  implied
45              when BYTES is not specified
46
47       -t, --format=TYPE
48              select output format or formats
49
50       -v, --output-duplicates
51              do not use * to mark line suppression
52
53       -w[BYTES], --width[=BYTES]
54              output  BYTES bytes per output line; 32 is implied when BYTES is
55              not specified
56
57       --traditional
58              accept arguments in third form above
59
60       --help display this help and exit
61
62       --version
63              output version information and exit
64
65   Traditional format specifications may be intermixed; they accumulate:
66       -a     same as -t a,  select named characters, ignoring high-order bit
67
68       -b     same as -t o1, select octal bytes
69
70       -c     same as -t c,  select printable characters or backslash escapes
71
72       -d     same as -t u2, select unsigned decimal 2-byte units
73
74       -f     same as -t fF, select floats
75
76       -i     same as -t dI, select decimal ints
77
78       -l     same as -t dL, select decimal longs
79
80       -o     same as -t o2, select octal 2-byte units
81
82       -s     same as -t d2, select decimal 2-byte units
83
84       -x     same as -t x2, select hexadecimal 2-byte units
85
86   TYPE is made up of one or more of these specifications:
87       a      named character, ignoring high-order bit
88
89       c      printable character or backslash escape
90
91       d[SIZE]
92              signed decimal, SIZE bytes per integer
93
94       f[SIZE]
95              floating point, SIZE bytes per float
96
97       o[SIZE]
98              octal, SIZE bytes per integer
99
100       u[SIZE]
101              unsigned decimal, SIZE bytes per integer
102
103       x[SIZE]
104              hexadecimal, SIZE bytes per integer
105
106       SIZE is a number.   For  TYPE  in  [doux],  SIZE  may  also  be  C  for
107       sizeof(char),   S  for  sizeof(short),  I  for  sizeof(int)  or  L  for
108       sizeof(long).  If TYPE is f, SIZE may also be F  for  sizeof(float),  D
109       for sizeof(double) or L for sizeof(long double).
110
111       Adding  a z suffix to any type displays printable characters at the end
112       of each output line.
113
114   BYTES is hex with 0x or 0X prefix, and may have a multiplier suffix:
115       b      512
116
117       KB     1000
118
119       K      1024
120
121       MB     1000*1000
122
123       M      1024*1024
124
125       and so on for G, T, P, E, Z, Y.
