  3. what shell is being used.
If the OP is unwilling to provide a small set of sample input files, corresponding desired sample output, and a clear explanation of the processing to be performed to produce that desired output from the input files; there isn't a high likelihood that a working solution will be provided here. (Nor is there much incentive for the volunteers here to download 150Kb of data to try to guess at what needs to be done.)

Furthermore, when asked "what have you tried and where are you stuck?", the response was two repeated demands for us to provide working code.

The UNIX & Linux Forums is here to help people learn how to use the great tools available on UNIX and Linux systems to perform wondrous computing tasks. We are not here to work as unpaid programming staff for someone who is unwilling to demonstrate any attempt to do any work to get the job done.
