|
|
.Xr Hexdump 1 ,
|
|

|
|
.Nm "" ,
|
|

|
|
It does not provide compatibility for the
|
|
.Fl s

|
|
or the
|
|
.Fl P ,
|
|
.Fl p ,

|
or
|
|
.Fl w
|
|
options, nor is compatibility provided for the ``label'' component
|
|
of the offset syntax.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width Fl

|
|
per line. Control characters are printed as their names instead of as
|
|
c style escapes.

|
|
selected.
|
|
.It Fl c
|
|
.Em One-byte character display .
|
|
Display the input offset in octal, followed by sixteen
|
|
space-separated, three column, space-filled, characters of input data
|
|
per line. Control characters are printed at c style escapes, or as
|
|
three octal digits, if no c escape exists for the character.
|
|
.It Fl d
|
|
.Em Two-byte decimal display .
|
|

|
|

|
.It Fl e
|
|
.Em Eight-byte floating point display .
|
|
Display the input offset in octal, followed by two space-separated,
|
|

|
|
floating point, per line.

|
|

|
|
point, per line.
|
|
.It Fl H
|
|
.Em Four-byte hex display .
|
|
Display the input offset in octal, followed by four space-separated,
|
|
eight column, zero filled, four byte units of input data, in hex,
|
|
per line.
|
|
.It Fl h
|
|
.Em Two-byte hex display .
|
|
Display the input offset in octal, followed by eight space-separated,
|
|

|
|
per line.
|
|
.It Fl I
|
|
.Em Four-byte decimal display .
|
|
Display the input offset in octal, followed by four space-separated,
|
|

|
|
decimal, per line.
|
|
.It Fl i
|
|
.Em Two-byte decimal display .
|
|
Display the input offset in octal, followed by eight space-separated,
|
|
six column, space filled, two-byte units of input data, in decimal,
|
|
per line.
|

space-separated, eleven column, zero-filled, four-byte units
|
|
of input data, in octal, per line.
|
|
.It Fl o
|

.Em Two-byte octal display .
|
|
Display the input offset in octal, followed by eight
|
|
space-separated, six column, zero-filled, two-byte units
|
|
of input data, in octal, per line.
|
|
.It Fl t Ar type_string
|
|
Specify one or more output types. The
|
|
.Em type_string
|
|
option-argument must be a string specifying the types to be used when
|
|
writing the input data. The string must consist of the type
|
|
specification characters:
|
|
.Pp
|
|
.Cm a
|
|
selects US-ASCII output, with control characters replaced with their
|
|
names instead of as c escape sequences. See also the
|
|
.Cm _u
|
|
conversion provided by hexdump(1).
|
|
.Pp
|
|
.Cm c
|
|
selects a standard character based conversion. See also the
|
|
.Cm _c
|
|
conversion provided by hexdump(1).
|
|
.Pp
|
|
.Cm f
|
|
selects the floating point output format. This type character can be
|
|
optionally followed by the characters
|
|
.Cm 4
|
|
or
|
|
.Cm F
|
|
to specify four byte floating point output, or
|
|
.Cm 8
|
|
or
|
|
.Cm L
|
|
to specify eight byte floating point output. The default output
|
|
format is eight byte floats. See also the
|
|
.Cm e
|
|
conversion provided by hexdump(1).
|
|
.Pp
|
|
.Cm d ,
|
|
.Cm o ,
|
|
.Cm u ,
|
|
or
|
|
.Cm x
|
|
select decimal, octal, unsigned decimal, or hex output respectively.
|
|
These types can optionally be followed by
|
|
.Cm C
|
|
or
|
|
.Cm 1
|
|
to specify one byte output,
|
|
.Cm S
|
|
or
|
|
.Cm 2
|
|
to specify two byte output,
|
|
.Cm I
|
|
or
|
|
.Cm 4
|
|
to specify four byte output, or
|
|
.Cm L
|
|
or
|
|
.Cm 8
|
|
to specify eight byte output. The default output format is in four
|
|
byte quantities. See also the
|
|
.Cm d ,
|
|
.Cm o ,
|
|
.Cm u ,
|
|
and
|
|
.Cm x
|
|
conversions provided by hexdump(1).
|
|
.\"(a|c|f[FLD]?|[doux][C1S2I4L8]?)*
|
|
.It Fl v
|
|
The
|
|
.Fl v
|
|
option causes
|
|
.Nm
|
|
to display all input data.
|
|
Without the
|
|
.Fl v
|
|
option, any number of groups of output lines, which would be
|
|
identical to the immediately preceding group of output lines (except
|
|
for the input offsets), are replaced with a line comprised of a
|
|
single asterisk.
|
|
.It Fl X
|
|
Same as
|
|
.Fl H .
|
|
.It Fl x
|

|
|
.El
|
|
.Pp
|
|
For each input file,
|
|
.Nm
|
|
sequentially copies the input to standard output, transforming the
|
|
data according to the options given. If no options are specified, the
|
|
default display is equivalent to specifying the
|
|
.Fl o
|
|
option.
|
|
.Pp
|
|
.Nm
|
|
exits 0 on success and >0 if an error occurred.

after he augmented the deprecated od syntax to include things he felt

had been missing for a long.
