Hey guys,

I have a huge file that needs to be edited using a hex editor. Right now
i'm using khexedit. The only problem is that this is a multiuser
environmnet and every time the file is loaded it uses 80 to 90% of
memory. It loads the "whole" file into memory. Everyone else's processes
suffer because of it.

The section of the file that needs to be edited is the first 2k. To
extract this section and read it into the editor, make the changes is
not a problem. The challenge comes in now that I want to put it back at
the begining of the file.

to extract,
$ dd if=pathtoverybigfile of=pathtosectionoffile bs=2k count=1

How to reverse this so that a put the changed section back into the orig
file?

Thanks guys.

Rafael.
