Another Idea for the same solution..
Hi
Thanks for the solution.. We had come up with a solution for comparing the huge data..
Since we are comparing huge data of flat file records, the follwing can be done
A hash function may be used like you mentioned below for each rows on the flat files, making the comparison easier.
But Is there a utility hash function in unix same as that of orahash in oracle that wud encrypt each new row uniquely within a few set of characters or numbers.
Then we cud use only those hashed codes to compare with the old hash codes of the prev day file and which wud make processing faster too...

diffpdf
DIFFPDF(1) General Commands Manual DIFFPDF(1)
NAME
diffpdf - compare two PDF files textually or visually
SYNOPSIS
diffpdf [file1] [file2]
DESCRIPTION
This manual page very briefly documents the diffpdf command. (Click the GUI's Help button or press F1 for more information.)
DiffPDF is a GUI application used to compare two PDF files.
By default the comparison is of the words on each pair of pages, but comparing character by character is also supported (e.g., for logo-
graphic languages). And there's also support for comparing the pages by appearance (for example, if a diagram is changed or if a paragraph
is reformatted, or a font changed). It is also possible to compare particular pages or page ranges. For example, if there are two versions
of a PDF file, one with pages 1-12 and the other with pages 1-13 because of an extra page having been added as page 4, they can be compared
by specifying two page ranges, 1-12 for the first and 1-3, 5-13 for the second. This will make DiffPDF compare pages in the pairs (1, 1),
(2, 2), (3, 3), (4, 5), (5, 6), and so on, to (12, 13).
If the program is passed two PDF filenames on the command line it will start up and compare those files in Text mode (or in Appearance mode
if the filenames are preceded by -a or --appearance).
