22 !!DESCRIPTION
23
24
25 Write an unambiguous representation, octal bytes by default,
26 of FILE to standard output. With no FILE, or when FILE is -,
27 read standard input.
28
29
30 __-A__, __--address-radix__=''RADIX''
31
32
33 decide how file offsets are printed
34
35
36 __-j__, __--skip-bytes__=''BYTES''
37
38
39 skip BYTES input bytes first on each file
40
41
42 __-N__, __--read-bytes__=''BYTES''
43
44
45 limit dump to BYTES input bytes per file
46
47
48 __-s__, __--strings__[[=''BYTES'']
49
50
51 output strings of at least BYTES graphic chars
52
53
54 __-t__, __--format__=''TYPE''
55
56
57 select output format or formats
58

62
63 do not use * to mark line suppression
64

90 __Pre-POSIX format specifications may be intermixed, they
91 accumulate:__
92
93
94 __-a__
95
96
97 same as __-t__ a, select named characters
98
99
100 __-b__
101
102
103 same as __-t__ oC, select octal bytes
104
105
106 __-c__
107
108
109 same as __-t__ c, select ASCII characters or backslash
110 escapes

117 shorts

130
131
132 __-i__
133
134
135 same as __-t__ d2, select decimal shorts
136
137
138 __-l__
139
140
141 same as __-t__ d4, select decimal longs
142

148
149
150 __-x__
151
152
153 same as __-t__ x2, select hexadecimal shorts
154
155
156 For older syntax (second call format), OFFSET means
157 __-j__ OFFSET. LABEL is the pseudo-address at first byte
158 printed, incremented when dump is progressing. For OFFSET
159 and LABEL, a 0x or 0X prefix indicates hexadecimal, suffixes
160 maybe . for octal and b multiply by 512.
161
162
163 TYPE is made up of one or more of these
164 specifications:
165
166
167 a
168
169
170 named character
171
172
173 c
174
175
176 ASCII character or backslash escape
177
178
179 d[[SIZE]
180
181
182 signed decimal, SIZE bytes per integer
183
184
185 f[[SIZE]
186
187
188 floating point, SIZE bytes per integer
189
190
191 o[[SIZE]
192
193
194 octal, SIZE bytes per integer
195
196
197 u[[SIZE]
198
199
200 unsigned decimal, SIZE bytes per integer
201
202
203 x[[SIZE]
204
205
206 hexadecimal, SIZE bytes per integer
207
208
209 SIZE is a number. For TYPE in doux, SIZE may also be C for
210 sizeof(char), S for sizeof(short), I for sizeof(int) or L
211 for sizeof(long). If TYPE is f, SIZE may also be F for
212 sizeof(float), D for sizeof(double) or L for sizeof(long
213 double).
214
215
216 RADIX is d for decimal, o for octal, x for hexadecimal or n
217 for none. BYTES is hexadecimal with 0x or 0X prefix, it is
218 multiplied by 512 with b suffix, by 1024 with k and by
219 1048576 with m. Adding a z suffix to any type adds a display
220 of printable characters to the end of each line of output.
221 __-s__ without a number implies 3. __-w__ without a
222 number implies 32. By default, od uses __-A__ o __-t__
223 d2 __-w__ 16.
