<H2>DESCRIPTION</H2>
|
|
|
|
|
|
<P>
|
|
|
|
Write an unambiguous representation, octal bytes by default,
|
|
of FILE to standard output. With more than one FILE argument,
|
|
concatenate them in the listed order to form the input.
|
|
<P>
|
|
|
|
With no FILE, or when FILE is -, read standard input.
|
|
<P>
|
|
|
|
If first and second call formats both apply, the second format is assumed
|
|
if the last operand begins with + or (if there are 2 operands) a digit.
|
|
An OFFSET operand means <B>-j</B> OFFSET. LABEL is the pseudo-address
|
|
at first byte printed, incremented when dump is progressing.
|
|
For OFFSET and LABEL, a 0x or 0X prefix indicates hexadecimal;
|
|
suffixes may be . for octal and b for multiply by 512.
|
|
<P>
|
|
|
|
Mandatory arguments to long options are mandatory for short options too.

SIZE is a number. For TYPE in [doux], SIZE may also be C for
|
|
sizeof(char), S for sizeof(short), I for sizeof(int) or L for
|
|
sizeof(long). If TYPE is f, SIZE may also be F for sizeof(float), D
|
|
for sizeof(double) or L for sizeof(long double).
|
|
<P>
|
|
|
|
Adding a z suffix to any type displays printable characters at the end of
|
|
each output line.
