If you don't know what you want, I have no idea whether what I suggest will succeed. I am guessing that the intent of the pipeline:
is to extract the first 10000*1000 bytes from /var/dump.log and then extract the first 6000*1000 bytes from that. That is equivalent to extracting the first 6000*1000 bytes from /var/dump.log. If you had specified 10000kB and 6000kB, that is what would be done according to the Linux head man page. If you had used 10000K and 6000K, the multiplier would be 1024 instead of 1000 according to the Linux head man page. If the count had been negative in the 2nd call to head, the command line would make more sense since it would then be getting the last 6000*(1000 or 1024) bytes from the first 10000*(1000 or 1024) bytes. But, I can only work with the command line you supplied and guess at the multiplier (or block size) you want. So:
might do what you want. If you want a block size of 1024 instead of 1000, change the bs=1000 to bs=1024.
If wanted the last 6000 blocks of the first 10000 blocks from the file, you could try:

I'm doing a bit of hex editing with dd and I can replace values fairly simply. However, I've run across a situation where I need to delete bytes in the file and I'm not sure how to do that. For example:
Input file has:

Output needs to be:
123abc90
I tried this:

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!!

What is the easiest way to inspect the bytes stored in a file?
Ideally, If my file was 10 bytes each of which had only the high bit set, I'd be able to browse for it and get output like this:
01 - 10000000
02 - 10000000
03 - 10000000
04 - 10000000
05 - 10000000
06 - 10000000
07 -... (7 Replies)

While running script I am getting an error like
Few lines in data are not being processed.
After googling it I came to know that adding such line would give some memory to it

Is that memory limit is based on RAM we have on... (1 Reply)
Hi,
If I want to copy a 1024 byte data stream in to the target location in 3-bytes chunk, I guess I can use the following script.
dd bs=1024 count=3 if=/src of=/dest
But, I would like to know, how to do it via a C program. I have tried this with memcpy(), that did not help. (3 Replies)
Hello guys. I really hope someone will help me with this one..
So, I have to write this script who:

Graphics::Primitive::Insets - Space between things
DESCRIPTION
Graphics::Primitive::Insets represents the amount of space that surrounds something. This object can be used to represent either padding
or margins (in the CSS sense, one being inside the bounding box, the other being outside)
SYNOPSIS
use Graphics::Primitive::Insets;
my $insets = Graphics::Primitive::Insets->new({
top => 5,
bottom => 5,
left => 5,
right => 5
});
METHODS
Constructor
new Creates a new Graphics::Primitive::Insets.
Instance Methods
as_array
Return these insets as an array in the form of top, right, bottom and left.
bottom
Set/Get the inset from the bottom.
equal_to
Determine if these Insets are equal to another.
left
Set/Get the inset from the left.
right
Set/Get the inset from the right.
top Set/Get the inset from the top.
zero
Sets all the insets (top, left, bottom, right) to 0.
