This, however does produce correct output.
1. this emulates your approach - prepending "0x" to a hex number
2. it does produce correct output, I believe.
3. So, is it feasible to consider printf
sed or awk to pipe (or process substitution) prepended data to printf ?
data to printf?
Is there some reason we must only use awk to output

Hi all,
I have a small script to convert my HexaDecimal Input to Decimal as output.
#!/bin/ksh
hd=00208060
dec=`printf %d $hd`
echo $dec
Output of the above program:
printf: 00208060 not completely converted

But my expected output is "2130016".
How can i acheive this.

I have a text file of alphanumeric values listed one by one. I have to convert them to hexadecimal equivalents for each character seperated by ":" in Unix bash shell script. For example, 12345678 has to be converted to 31:32:33:34:35:36:37:38 (10 Replies)

tprintf
PRINTF(9) BSD Kernel Developer's Manual PRINTF(9)NAME
printf, uprintf, tprintf, log -- formatted output conversion
SYNOPSIS
#include <sys/types.h>
#include <sys/systm.h>
int
printf(const char *fmt, ...);
void
tprintf(struct proc *p, int pri, const char *fmt, ...);
int
uprintf(const char *fmt, ...);
#include <sys/syslog.h>
void
log(int pri, const char *fmt, ...);
DESCRIPTION
The printf(9) family of functions are similar to the printf(3) family of functions. The different functions each use a different output
stream. The uprintf() function outputs to the current process' controlling tty, while printf() writes to the console as well as to the log-
ging facility. The tprintf() function outputs to the tty associated with the process p and the logging facility if pri is not -1. The log()
function sends the message to the kernel logging facility, using the log level as indicated by pri.
Each of these related functions use the fmt parameter in the same manner as printf(3). However, printf(9) adds two other conversion speci-
fiers.
The %b identifier expects two arguments: an int and a char *. These are used as a register value and a print mask for decoding bitmasks.
The print mask is made up of two parts: the base and the arguments. The base value is the output base expressed as an integer value; for
example, 10 gives octal and 20 gives hexadecimal. The arguments are made up of a sequence of bit identifiers. Each bit identifier begins
with an integer value which is the number of the bit (starting from 1) this identifier describes. The rest of the identifier is a string of
characters containing the name of the bit. The string is terminated by either the bit number at the start of the next bit identifier or NUL
for the last bit identifier.
The %D identifier is meant to assist in hexdumps. It requires two arguments: a u_char * pointer and a char * string. The memory pointed to
be the pointer is output in hexadecimal one byte at a time. The string is used as a delimiter between individual bytes. If present, a width
directive will specify the number of bytes to display. By default, 16 bytes of data are output.
The log() function uses syslog(3) level values LOG_DEBUG through LOG_EMERG for its pri parameter (mistakenly called 'priority' here). Alter-
natively, if a pri of -1 is given, the message will be appended to the last log message started by a previous call to log(). As these mes-
sages are generated by the kernel itself, the facility will always be LOG_KERN.
RETURN VALUES
The printf() and the uprintf() functions return the number of characters displayed.
EXAMPLES
This example demonstrates the use of the %b and %D conversion specifiers. The function
void
printf_test(void)
{
printf("reg=%b
", 3, "102BITTWO1BITONE
");
printf("out: %4D
", "AAAA", ":");
}
will produce the following output:
reg=3<BITTWO,BITONE>
out: 41:41:41:41
The call
log(LOG_DEBUG, "%s%d: been there.
", sc->sc_name, sc->sc_unit);
will add the appropriate debug message at priority ``kern.debug'' to the system log.
