Well, there is nothing which mentions the end of each block. 0xff 0x33 represents the end of file, is that right?
Following code extracts the data from which you want, but there is no check for end of block as I am still confused. May be a larger file with expected output can clarify it.

Or is it that once we encounter 0xff 0x33, we should stop?

Hi all,
Does anybody know or guide me on how to remove the first N bytes and the last N bytes from a binary file? Is there any AWK or SED or any command that I can use to achieve this?
Your help is greatly appreciated!!

Hello,
I have come across the necessity for me to deal with binary sequences and I had a few questions.
1- Does any UNIX scripting language provide any tool or command for converting text data to binary sequences? Example of binary sequence: "0x97 0x93 0x85 0x40 0xd5 0xd6 0xd7"
2- If I want... (2 Replies)
Hi,
I have an one-line file consisting of a sequence of 660 letters. I would like to extract 9-letter blocks iteratively:
ASDFGHJKLQWERTYUIOPZXCVBNM
first block: ASDFGHJKL
1nd block: SDFGHJKLQ
What I have so far only gives me the first block, can anyone please explain why?

Hi,
This is part of a large text file I need to separate out.
I'd like some help to build a shell script that will extract the text between sets of dashed lines, write that to a new file using the whole or part of the first text string as the new file name, then move on to the next one and... (7 Replies)
The title is clear: why does ext3 allocate 8 blocks for files that are few bytes long?
If I create a file named "test", put a few chars in it, and then I run:
stat test
I get that "Blocks: 8"
I searched in the web and found that ext does that, it allocates 8 blocks even if It doesn't need... (4 Replies)
Hello guys. I really hope someone will help me with this one..
So, I have to write this script who:

err_error_string_n
ERR_error_string(3) OpenSSL ERR_error_string(3)NAME
ERR_error_string, ERR_error_string_n, ERR_lib_error_string, ERR_func_error_string, ERR_reason_error_string - obtain human-readable error
message
SYNOPSIS
#include <openssl/err.h>
char *ERR_error_string(unsigned long e, char *buf);
void ERR_error_string_n(unsigned long e, char *buf, size_t len);
const char *ERR_lib_error_string(unsigned long e);
const char *ERR_func_error_string(unsigned long e);
const char *ERR_reason_error_string(unsigned long e);
DESCRIPTION
ERR_error_string() generates a human-readable string representing the error code e, and places it at buf. buf must be at least 120 bytes
long. If buf is NULL, the error string is placed in a static buffer. ERR_error_string_n() is a variant of ERR_error_string() that writes
at most len characters (including the terminating 0) and truncates the string if necessary. For ERR_error_string_n(), buf may not be NULL.
The string will have the following format:
error:[error code]:[library name]:[function name]:[reason string]
error code is an 8 digit hexadecimal number, library name, function name and reason string are ASCII text.
ERR_lib_error_string(), ERR_func_error_string() and ERR_reason_error_string() return the library name, function name and reason string
respectively.
The OpenSSL error strings should be loaded by calling ERR_load_crypto_strings(3) or, for SSL applications, SSL_load_error_strings(3) first.
If there is no text string registered for the given error code, the error string will contain the numeric code.
ERR_print_errors(3) can be used to print all error codes currently in the queue.
RETURN VALUES
ERR_error_string() returns a pointer to a static buffer containing the string if buf == NULL, buf otherwise.
ERR_lib_error_string(), ERR_func_error_string() and ERR_reason_error_string() return the strings, and NULL if none is registered for the
error code.
SEE ALSO err(3), ERR_get_error(3), ERR_load_crypto_strings(3), SSL_load_error_strings(3)ERR_print_errors(3)HISTORY
ERR_error_string() is available in all versions of SSLeay and OpenSSL. ERR_error_string_n() was added in OpenSSL 0.9.6.
