folding a string
is there any otherway to break into 80 byte per line with putting a line break...
As fold does not fit in the current schema .
here is the document which says
breaking the lines to have a maximum of width column positions
(or bytes, if the -b option is specified). The fold command breaks
lines by inserting a newline character so that each output line is the
maximum width possible that does not exceed the specified number of
column positions (or bytes). A line cannot be broken in the middle of
a character. If no files are specified or if a file name of - is
specified, the standard input is used.

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!!

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)

FOLD(1) BSD General Commands Manual FOLD(1)
NAME
fold -- fold long lines for finite width output device
SYNOPSIS
fold [-bs] [-w width] [file ...]
DESCRIPTION
The fold utility is a filter which folds the contents of the specified files, or the standard input if no files are specified, breaking the
lines to have a maximum of 80 columns.
The options are as follows:
-b Count width in bytes rather than column positions.
-s Fold line after the last blank character within the first width column positions (or bytes).
-w width
Specify a line width to use instead of the default 80 columns. The width value should be a multiple of 8 if tabs are present, or the
tabs should be expanded using expand(1) before using fold.
ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of fold as described in environ(7).
SEE ALSO
expand(1), fmt(1)
STANDARDS
The fold utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
BUGS
If underlining (see ul(1)) is present it may be messed up by folding.
