Thanks Ahamed!
Is there any other way. I cannot use just tr to replace the newline chars with space while i read data. My source data also have some newline chars in it in each records.
Also the Source data has spaces all special char, binary data etc...
Is it possible to read file as one big blob and then use a loop somehow to remove every 3001th char?
Thanks

SCRIPT(1) BSD General Commands Manual SCRIPT(1)
NAME
script -- make typescript of terminal session
SYNOPSIS
script [-a] [-c COMMAND] [-f] [-q] [-t] [file]
DESCRIPTION
Script makes a typescript of everything printed on your terminal. It is useful for students who need a hardcopy record of an interactive
session as proof of an assignment, as the typescript file can be printed out later with lpr(1).
If the argument file is given, script saves all dialogue in file. If no file name is given, the typescript is saved in the file typescript.
Options:
-a Append the output to file or typescript, retaining the prior contents.
-c COMMAND
Run the COMMAND rather than an interactive shell. This makes it easy for a script to capture the output of a program that behaves
differently when its stdout is not a tty.
-f Flush output after each write. This is nice for telecooperation: One person does `mkfifo foo; script -f foo' and another can super-
vise real-time what is being done using `cat foo'.
-q Be quiet.
-t Output timing data to standard error. This data contains two fields, separated by a space. The first field indicates how much time
elapsed since the previous output. The second field indicates how many characters were output this time. This information can be used
to replay typescripts with realistic typing and output delays.
The script ends when the forked shell exits (a control-D to exit the Bourne shell (sh(1)), and exit, logout or control-d (if ignoreeof is not
set) for the C-shell, csh(1)).
Certain interactive commands, such as vi(1), create garbage in the typescript file. Script works best with commands that do not manipulate
the screen, the results are meant to emulate a hardcopy terminal.
ENVIRONMENT
The following environment variable is utilized by script:
SHELL If the variable SHELL exists, the shell forked by script will be that shell. If SHELL is not set, the Bourne shell is assumed. (Most
shells set this variable automatically).
SEE ALSO
csh(1) (for the history mechanism), scriptreplay(1).
HISTORY
The script command appeared in 3.0BSD.
BUGS
Script places everything in the log file, including linefeeds and backspaces. This is not what the naive user expects.
AVAILABILITY
The script command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
