I'm trying to avoid printing the "f's" that are printing for the fields
in red below, but for now is secondary that issue:
If you want, better please help me in extract the last sequences of interest to me and is at the end of the sub-block and begins with 84 0e, where 0e is the length, so is needed to extract the 84 and the next 14 bytes after 0e, separating each byte by "|". As is part of the same block, print as before in the same line.
I'm attaching and image showing in red the bytes I mention.
I've added 0x03, 0x84 at the end of the intrim_pat1, and it seems is pending add some other code.
PD: 84 0E will appear at the end of sub-block, won't appear after 0x03, but I've added in intrim_pat1 because is the way I see possible to do it for me.
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:

- formats that file to ext3

ATOMIC_INC(3) BSD Library Functions Manual ATOMIC_INC(3)NAME
atomic_inc, atomic_inc_32, atomic_inc_uint, atomic_inc_ulong, atomic_inc_ptr, atomic_inc_64, atomic_inc_32_nv, atomic_inc_uint_nv,
atomic_inc_ulong_nv, atomic_inc_ptr_nv, atomic_inc_64_nv -- atomic increment operations
SYNOPSIS
#include <sys/atomic.h>
void
atomic_inc_32(volatile uint32_t *ptr);
void
atomic_inc_uint(volatile unsigned int *ptr);
void
atomic_inc_ulong(volatile unsigned long *ptr);
void
atomic_inc_ptr(volatile void *ptr);
void
atomic_inc_64(volatile uint64_t *ptr);
uint32_t
atomic_inc_32_nv(volatile uint32_t *ptr);
unsigned int
atomic_inc_uint_nv(volatile unsigned int *ptr);
unsigned long
atomic_inc_ulong_nv(volatile unsigned long *ptr);
void *
atomic_inc_ptr_nv(volatile void *ptr);
uint64_t
atomic_inc_64_nv(volatile uint64_t *ptr);
DESCRIPTION
The atomic_inc family of functions increment (by one) the variable referenced by ptr in an atomic fashion.
The *_nv() variants of these functions return the new value.
The 64-bit variants of these functions are available only on platforms that can support atomic 64-bit memory access. Applications can check
for the availability of 64-bit atomic memory operations by testing if the pre-processor macro __HAVE_ATOMIC64_OPS is defined.
SEE ALSO atomic_ops(3)HISTORY
The atomic_inc functions first appeared in NetBSD 5.0.
