Sorry my mistake that was due to a typo. I have edited and amended above as required.

The logic behing it is that the first csv (FILE1.CSV) file is produced but may have incorrect figures associated with it. Once the information is readily available the second csv (FILE2.CSV) is produced with the correct figures and any missing codes.

Once this has been done file 1 and file 2 need to be merged to have the correct figures from file 2 and also to include any missing codes that are on file 2 but not file 1.

I need to do this in Unix, my initial thoughts were to use the join command but not sure if this is possible but may be some use of lookup could be done... again i am a programming and unix newbie so would appreciate any assistance.

Thanks
