Thank you RudiC. I tried it but the output is nothing, which I dont think is wrong. The answer is there, its just that whether the answer are spaces or tabs, these are not being printed as " " or "t". In other words, for the file
which is ABCDtabAspacespacespaceL
I would expect awk to print these separators, something like:

io::pipe
IO::Pipe(3pm) Perl Programmers Reference Guide IO::Pipe(3pm)NAME
IO::Pipe - supply object methods for pipes
SYNOPSIS
use IO::Pipe;
$pipe = new IO::Pipe;
if($pid = fork()) { # Parent
$pipe->reader();
while(<$pipe>) {
...
}
}
elsif(defined $pid) { # Child
$pipe->writer();
print $pipe ...
}
or
$pipe = new IO::Pipe;
$pipe->reader(qw(ls -l));
while(<$pipe>) {
...
}
DESCRIPTION
"IO::Pipe" provides an interface to creating pipes between processes.
CONSTRUCTOR
new ( [READER, WRITER] )
Creates an "IO::Pipe", which is a reference to a newly created symbol (see the "Symbol" package). "IO::Pipe::new" optionally takes two
arguments, which should be objects blessed into "IO::Handle", or a subclass thereof. These two objects will be used for the system call
to "pipe". If no arguments are given then method "handles" is called on the new "IO::Pipe" object.
These two handles are held in the array part of the GLOB until either "reader" or "writer" is called.
METHODS
reader ([ARGS])
The object is re-blessed into a sub-class of "IO::Handle", and becomes a handle at the reading end of the pipe. If "ARGS" are given
then "fork" is called and "ARGS" are passed to exec.
writer ([ARGS])
The object is re-blessed into a sub-class of "IO::Handle", and becomes a handle at the writing end of the pipe. If "ARGS" are given
then "fork" is called and "ARGS" are passed to exec.
handles ()
This method is called during construction by "IO::Pipe::new" on the newly created "IO::Pipe" object. It returns an array of two objects
blessed into "IO::Pipe::End", or a subclass thereof.
