binary2ascii - Convert binary numbers to textual representation
binary2ascii [flags]
binary2ascii reads input consisting of binary numbers and converts them
to their textual representation. Command line flags specify the type and size
of the binary numbers and provide control over the format of the output.
Unsigned integers may be written out in binary, octal, decimal, or
hexadecimal. Signed integers may be written out only in binary or decimal.
Floating point numbers may be written out only in decimal, either in standard
or scientific notation. (If you want to examine the binary representation of
floating point numbers, just treat the input as a sequence of unsigned
characters.)
Long options may not be available on some systems.
- -b,--base <base>
- Base for integer conversions: b(binary),d(ecimal),
h(exadecimal), o(ctal), or 2,8,10, or 16.
- -d,--delimit
- Delimit the output as per the locale. This is the default
on systems in which printf(3) supports delimitation. If
delimitation is not enabled, floating point numbers will have a decimal
point and no separation of groups, integers no delimiters at all. With
this option, the decimal separator will be chosen according to the locale
(which, for example, may make it a comma), and non-fractional digits will
be grouped and separated according to the rules for the locale in force.
For American English, this means groups of three digits separated by
commas, whereas for German in Germany it means groups of three digits
separated by periods.
- -D,--do-not-delimit
- Do not delimit the output as per the -d option.
- -e,--exponential
- Use exponential (scientific) notation.
- -h,--help
- print help message
- -l,--linefeed
- add a linefeed after every 0x0A value if the size is char,
short, int, or long, that is, the sizes that might represent a
character.
- -L,locale <locale>
- Set the LC_NUMERIC facet of the locale to
<locale>.
- -n,--number <number>
- number of items to print per line.
- -o,--offset <offset>
- byte offset at which to start.
- -p,--precision <precision>
- the precision to use when printing floating point
numbers.
- -s,--sizes
- print sizes of types on current machine and related
information
- -t,--type <type>
- set type and size of input
- -x,--no-hex-mark
- do not mark hexadecimal output with the prefix 0x.
- -V,--verbose
- be verbose.
- -v,--version
- print version information.
- -w,--width
- minimum field width.
- -X,--explain-exit-codes
- print a summary of the exit status codes.
- -z,--zero-pad-integers
- zero pad on left.
- -Z,--do-not-zero-pad-integers
- do not zero pad on left
The following are the possible input types. Note that some types may not be
available on some machines.
d double
f float
q long double
sc signed char
ss signed short
si signed int
sl signed long
sq signed long long
uc unsigned char
us unsigned short
ui unsigned int
ul unsigned long
uq unsigned long long
The following values are returned on exit:
- 0 SUCCESS
- The input was successfully converted.
- 1 INFO
- The user requested information such as the version number
or usage synopsis and this has been provided.
- 2 SYSTEM ERROR
- An error resulted from a failure of the operating system
such as an i/o error or inability to allocate storage.
- 3 COMMAND LINE ERROR
- The program was called with invalid or inconsistent command
line flags.
- 5 INPUT ERROR
- This means that the input was ill-formed, that is that it
could not be interpreted as a number of the required type. For example, if
the input is 0x2A and a decimal value is called for, an INPUT ERROR will
be returned since 0x2A is not a valid representation of a decimal integer.
