17 Write an unambiguous representation, octal bytes by default,
18 of FILE to standard output. With more than one FILE argument,
19 concatenate them in the listed order to form the input.
20 With no FILE, or when FILE is \-, read standard input.
22 All arguments to long options are mandatory for short options.
24 \fB\-A\fR, \fB\-\-address\-radix\fR=\fIRADIX\fR

53 .SS "Traditional format specifications may be intermixed; they accumulate:"
56 same as \fB\-t\fR a, select named characters, ignoring high\-order bit
59 same as \fB\-t\fR o1, select octal bytes
62 same as \fB\-t\fR c, select ASCII characters or backslash escapes
65 same as \fB\-t\fR u2, select unsigned decimal 2\-byte units
68 same as \fB\-t\fR fF, select floats
71 same as \fB\-t\fR dI, select decimal ints
74 same as \fB\-t\fR dL, select decimal longs
77 same as \fB\-t\fR o2, select octal 2\-byte units
80 same as \fB\-t\fR d2, select decimal 2\-byte units
83 same as \fB\-t\fR x2, select hexadecimal 2\-byte units
85 If first and second call formats both apply, the second format is assumed
86 if the last operand begins with + or (if there are 2 operands) a digit.
87 An OFFSET operand means \fB\-j\fR OFFSET. LABEL is the pseudo\-address
88 at first byte printed, incremented when dump is progressing.
89 For OFFSET and LABEL, a 0x or 0X prefix indicates hexadecimal;
90 suffixes may be . for octal and b for multiply by 512.
92 TYPE is made up of one or more of these specifications:
95 named character, ignoring high\-order bit
98 ASCII character or backslash escape
101 signed decimal, SIZE bytes per integer
104 floating point, SIZE bytes per integer
107 octal, SIZE bytes per integer
110 unsigned decimal, SIZE bytes per integer
113 hexadecimal, SIZE bytes per integer
115 SIZE is a number. For TYPE in doux, SIZE may also be C for
116 sizeof(char), S for sizeof(short), I for sizeof(int) or L for
117 sizeof(long). If TYPE is f, SIZE may also be F for sizeof(float), D
118 for sizeof(double) or L for sizeof(long double).
120 RADIX is d for decimal, o for octal, x for hexadecimal or n for none.
121 BYTES is hexadecimal with 0x or 0X prefix, it is multiplied by 512
122 with b suffix, by 1024 with k and by 1048576 with m. Adding a z suffix to
123 any type adds a display of printable characters to the end of each line
124 of output. \fB\-\-string\fR without a number implies 3. \fB\-\-width\fR without a number
125 implies 32. By default, od uses \fB\-A\fR o \fB\-t\fR d2 \fB\-w16\fR.
