Remove duplicates in flat file

Hi all,
I have a issues while loading a flat file to the DB. It is taking much time.
When analyzed i found out that there are duplicates entry in the flat file.
There are 2 type of Duplicate entry.
1) is entire row is duplicate. ( i can use sort | uniq) to remove the duplicated entry.
2) the PK which are forming the composite columns are same for 2 records , but the other columns are different which is also rejected and only one is getting loaded. PFB an example for the same.
My Pk are 1 , 4, 6, 8 from the flat file which is going to be loaded into the DB.
Column names : 1 2 3 4 5 6 7 8 9 10
Records 1 a b c d e f g h i j
records 2 a k l d m f n h o p
So since my PK are alone same and the rest is also different the Loader is ommiting those records. Can you tell me a script by which i can omit the record 2.
Please help.. We are in brink of issues to be fixed before tomorrow evening.
Thanks in advance
Sam

XML2(1) 						      General Commands Manual							   XML2(1)

NAME
xml2 - convert xml documents in a flat format 2xml - convert flat format into xml html2 - convert html documents in a flat format 2html - convert flat format into html csv2 - convert csv files in a flat format 2csv - convert flat format into csv SYNOPSIS
<xml2|2xml|html2|2html|csv2|2csv> > outfile < infile DESCRIPTION
There are six tools. Except csv2 and and 2csv they don't take any command-line arguments. They are all simple filters which can be used to read files from standard input in one format and output it to standard output in another format. The flat format used by the tools is specific to these tools. It is a syntax for representing structured markup in a way that makes it easy to process with line-oriented tools. The same format is used for HTML and XML; in fact, you can think of html2 as converting HTML to XHTML and running xml2 on the result; likewise 2html and 2xml. (Of course, this isn't how the implementation works.) SEE ALSO
This program does normally not include any documentation in form of manpages. However it has a real excellent documentation online with a lot of example. In fact this manpage was based on this documentation. Please find it on: http://dan.egnor.name/xml2/ref Examples can be found here: http://dan.egnor.name/xml2/examples AUTHOR
xml2 was written by Dan Egnor. This manpage was written by Patrick Schoenfeld <schoenfeld@in-medias-res.com> for the Debian project, but may be used by others under the same terms as xml2 is distributed. BUGS
Bugs can be reported through the Debian Bug tracking system. 7h february 2008 XML2(1)
