1.9 pvalchev 70: .Xr hexdump 1 ,
1.1 deraadt 71: if called as
72: .Nm od ,
1.9 pvalchev 73: provides compatibility for the options described below.
1.1 deraadt 74: It does not provide compatibility for the
75: .Fl s
76: option (see
77: .Xr strings 1 )
78: or the
79: .Fl P ,
80: .Fl p ,
81: or
82: .Fl w
1.9 pvalchev 83: options, nor is compatibility provided for the ``label'' component
84: of the offset syntax.
85: .Pp
86: The options are as follows:
87: .Bl -tag -width Fl

89: .Em One-byte character display .
90: Display the input offset in octal, followed by sixteen
91: space-separated, three column, space-filled, characters of input data
1.12 jmc 92: per line.
93: Control characters are printed as their names instead of as C-style escapes.
1.9 pvalchev 94: .It Fl B
95: Same as
96: .Fl o .
97: .It Fl b
98: .Em One-byte octal display .
99: Display the input offset in octal, followed by sixteen
100: space-separated, three column, zero-filled, bytes of input data, in
1.12 jmc 101: octal, per line.

104: .Em One-byte character display .
105: Display the input offset in octal, followed by sixteen
106: space-separated, three column, space-filled, characters of input data
1.12 jmc 107: per line.
108: Control characters are printed as c style escapes, or as three octal digits,
109: if no c escape exists for the character.
1.9 pvalchev 110: .It Fl d
111: .Em Two-byte decimal display .
112: Display the input offset in octal, followed by eight
113: space-separated, five column, zero-filled, two-byte units

150: .Ar offset
151: bytes from the beginning of the input.
152: By default,

160: is interpreted as a hexadecimal number,
161: otherwise, with a leading
162: .Cm 0 ,

197: of input data, in octal, per line.
198: .It Fl t Ar type_string
1.12 jmc 199: Specify one or more output types.
200: The
1.9 pvalchev 201: .Em type_string
202: option-argument must be a string specifying the types to be used when
1.12 jmc 203: writing the input data.
204: The string must consist of the type specification characters:
1.9 pvalchev 205: .Pp
206: .Cm a
207: selects US-ASCII output, with control characters replaced with their
1.12 jmc 208: names instead of as c escape sequences.

223: This type character can be optionally followed by the characters
1.9 pvalchev 224: .Cm 4
225: or
226: .Cm F
227: to specify four byte floating point output, or
228: .Cm 8

1.12 jmc 231: to specify eight byte floating point output.
232: The default output format is eight byte floats.

265: .Cm 4
266: to specify four-byte output, or
267: .Cm 8
1.12 jmc 268: to specify eight-byte output.
269: The default output format is in four-byte quantities.

279: .It Fl v
280: The

282: option causes
283: .Nm
284: to display all input data.
285: Without the
286: .Fl v
287: option, any number of groups of output lines, which would be
288: identical to the immediately preceding group of output lines (except
289: for the input offsets), are replaced with a line comprised of a
