Thks for the help. I finally applied it succesfully today.
But, here comes another seperate but related problem. This time, I tried to convert from a Hex to Deci number by creating a new script with "%d" on the hex number, but it failed.
for file in `seq 1 256`; do printf "\x$file -- $file" ; done ; printf "\n"
produces the wrong output.
I want to show the ascii codes but need to output
a hexidecimal number sequence.
I know I should use awk to do this but i'm not sure how cause I forget.
what is the awk equivelant of seq... (5 Replies)
Hi All,
My main intension of is to convert the Hexstring stored in a char* into hex and then prefixing it with "0x" and suffix it with ','
This has to be done for all the hexstring char* is NULL.
Store the result prefixed with "0x" and suffixed with ',' in another char* and pass it to... (1 Reply)
Hi,
Is there really a difference between these two, std::hex and ios::hex??
I stumbled upon reading a line, "std::ios::hex is a bitmask (8 on gcc) and works with setf(). std::hex is the operator". Is this true?
Thanks (0 Replies)
Hi All,

I have a binary (hex) file I need to parse to get some data which are encoded this way:
.* b4 . . . 01 12 .* af .* 83 L1 x1 x2 xL 84 L2 y1 y2 yL
By another words there is a stream of hexadecimal bytes (in my example separated by space for better readability). I need to get value stored in... (3 Replies)

Result is not correct.
Looks like the number is too big.
Any idea?
Thx!

Hi guys,
First off, i'm a complete noob to UNIX and LINUX so apologies if I don't understand the basics!
I have a file which contains a hex value of '0D' at the end of each line when I look at it in a hex viewer.
I need to change it so it contains a hex value of '0D0A0A'
I thought... (10 Replies)

authbind-helper
AUTHBIND-HELPER(8) Debian Linux manual AUTHBIND-HELPER(8)NAME
authbind-helper - helper program to bind sockets to privileged ports without root
SYNOPSIS
/usr/lib/authbind/helper addr4-hex port-hex <socket
/usr/lib/authbind/helper addr6-hex port-hex 6 <socket
DESCRIPTION
helper is the program used by libauthbind, which is in turn used by authbind to allow programs which do not or should not run as root to
bind to low-numbered ports in a controlled way. See authbind(1).
It may also be used standalone, i.e. without assistance from authbind. Its standard input should be a TCP/IP socket, and it should be
passed two or three arguments.
The arguments are the address and port number, respectively, to which the caller desires that the socket be bound, and the address family
(ommitted for IPv4; the fixed string 6 for IPv6). addr4-hex and port-hex should be hex strings, without leading 0x, of exactly the right
length (8 and 4 digits, respectively), being a pair of hex digits for each byte in the address or port number when expressed in host byte
order. For example, the port argument is the result of something like sprintf(arg, "%04X", sin.sin_port). addr6-hex should be a string of
32 hex digits, being a pair for each byte in the address, in network byte order.
EXIT STATUS
helper will exit with code 0 on success.
If possible, helper will return an appropriate errno value as its exit status. If this is not possible it may exit with status 255 or with
an exit status corresponding to ENOSYS (Function not implemented).
ACCESS CONTROL
See authbind(1) for details of the access control regime implemented by helper.
