Thanks for the immediate response. Here are the details.
The File name would be the same in both the directories and both the files are expected to carry the same no of records with same value. My intention is just to reconcile both the files cell by cell and ofcourse write the difference if any to a new file.
File 1 in Directory A has some $value in 10 columns. The $value in this file is mixed - meaning some in scientific representation and some just whole numbers.
File 1 in Directory B has some $value in 10 columns. The $value in this file has all values upto 5 decimal places.
I intend to select the rows to compare by key identifiers. But I am just a beginner in Bash scripting and not sure of executing this.
Thanks.

I have two arrays I need to compare against a third, looking for matches, not differences. I think I'm going to have to convert the arrays to files and grep them, but I'm not too sure if there's a tool to enable me to matches specifically, instead of differences.
Thanks in advance!

apache::session::store::file
Apache::Session::Store::File(3pm) User Contributed Perl Documentation Apache::Session::Store::File(3pm)
NAME
Apache::Session::Store::File - Store persistent data on the filesystem
SYNOPSIS
use Apache::Session::Store::File;
my $store = new Apache::Session::Store::File;
$store->insert($ref);
$store->update($ref);
$store->materialize($ref);
$store->remove($ref);
DESCRIPTION
This module fulfills the storage interface of Apache::Session. The serialized objects are stored in files on your filesystem.
OPTIONS
This module requires one argument in the usual Apache::Session style. The name of the option is Directory, and the value is the full path
of the directory where you wish to place the files. Example
tie %s, 'Apache::Session::File', undef,
{Directory => '/tmp/sessions'};
NOTES
All session objects are stored in the same directory. Some filesystems, such as Linux's ext2fs, have O(n) performance where n is the
number of files in a directory. Other filesystems, like Sun's UFS, and Linux's reiserfs, do not have this problem. You should consider
your filesystem's performance before using this module to store many objects.
AUTHOR
This module was written by Jeffrey William Baker <jwbaker@acm.org>.
