The
utility is a filter which displays the specified files, or standard
input if no files are specified, in a user specified format.
The options are as follows:
-A base
Specify the input address base.
The argument
base
may be one of
dox
or
n
which specify decimal, octal, hexadecimal
addresses or no address, respectively.
-a
Output named characters.
Equivalent to
-t a
-B , o
Output octal shorts.
Equivalent to
-t o2
-b
Output octal bytes.
Equivalent to
-t o1
-c
Output C-style escaped characters.
Equivalent to
-t c
-D
Output unsigned decimal ints.
Equivalent to
-t u4
-d
Output unsigned decimal shorts.
Equivalent to
-t u2
-e , F
Output double-precision floating point numbers.
Equivalent to
-t fD
-f
Output single-precision floating point numbers.
Equivalent to
-t fF
-H , X
Output hexadecimal ints.
Equivalent to
-t x4
-h , x
Output hexadecimal shorts.
Equivalent to
-t x2
-I , L , l
Output signed decimal longs.
Equivalent to
-t dL
-i
Output signed decimal ints.
Equivalent to
-t dI
-j skip
Skip
skip
bytes of the combined input before dumping.
The number may be followed by one
of
b , k
or
m
which specify the units of the number as blocks (512 bytes), kilobytes and
megabytes, respectively.
-N length
Dump at most
length
bytes of input.
-O
Output octal ints.
Equivalent to
-t o4
-s
Output signed decimal shorts.
Equivalent to
-t d2
-t type
Specify the output format.
The
type
argument
is a string containing one or more of the following kinds of type specifiers:
a
Named characters
(ASCII
)
Control characters are displayed using the following names:
"000 NUL001 SOH002 STX003 ETX004 EOT005 ENQ"
"006 ACK007 BEL008 BS009 HT00a NL00b VT"
"00c FF00d CR00e SO00f SI010 DLE011 DC1"
"012 DC2013 DC3014 DC4015 NAK016 SYN017 ETB"
"018 CAN019 EM01a SUB01b ESC01c FS01d GS"
"01e RS01f US020 SP0ff DEL"
c
Characters in the default character set.
Non-printing characters are
represented as 3-digit octal character codes, except the following
characters, which are represented as C escapes:
NUL
\0
alert
\a
backspace
\b
newline
\n
carriage-return
\r
tab
\t
vertical tab
\v
Multi-byte characters are displayed in the area corresponding to the first
byte of the character.
The remaining bytes are shown as
`**'
[d | o | u | x
]
[C | S | I | L | n
]
Signed decimal
(d
)
octal
(o
)
unsigned decimal
(u
)
or
hexadecimal
(x
)
Followed by an optional size specifier, which may be either
C
(Vt char
)
S
(Vt short
)
I
(Vt int
)
L
(Vt long
)
or a byte count as a decimal integer.
f
[F | D | L | n
]
Floating-point number.
Followed by an optional size specifier, which may be either
F
(Vt float
)
D
(Vt double
)
or
L
(Vt long double
)
-v
Write all input data, instead of replacing lines of duplicate values with a
`*'
Multiple options that specify output format may be used; the output will
contain one line for each format.
If no output format is specified,
-t oS
is assumed.
ENVIRONMENT
The
LANG , LC_ALL
and
LC_CTYPE
environment variables affect the execution of
as described in
environ(7).
EXIT STATUS
Ex -std
COMPATIBILITY
The traditional
-s
option to extract string constants is not supported; consider using
strings(1)
instead.
