Shell Programming and Scripting

Don,

I apologise for that, I just gave the part of my file as sample file, My whole file is of around 2 GB, This was quite unusual, dint expected.
Can you plz help with this?

My code is working perfectly for the criteria you gave. I have repeatedly asked you to clearly state the criteria that specifies when field 1 is similar to field 2. You have repeatedly ignored that request. I clearly stated the assumptions I used to determine when my code would consider field 1 similar to field 2. Saying that my code produces the wrong results without clearly explaining what rules need to be followed to get the answer that you will consider correct doesn't tell us what we have to do to satisfy you.

Don,

To tell u frankly even i was not aware of the same until i ran your script that it won't work on that part of data.
Can you plz check and help on the same ?

My file is of huge size and it is impossible to share that huge data here. I really apologise for all the chaos caused.

Nikhil,
As I have repeatedly stated. We don't need to see all of your data. (Even if we did see all of your data, we apparently have no idea what the results are supposed to be.) There is nothing for me to check. The code I supplied is working exactly as I intended it to work based on your varying descriptions of the results you want. If you won't describe what needs to be done differently (instead of just repeating that my code is not working), I have nothing to check and I cannot help you.

Unless you post precise directions that we can follow that accurately describe what steps need to be taken to get the results you want, there is no possible way for any of us to help you. I could make some more wild guesses that would change the results that you say are wrong, but doing so would change results in previous posts that you seem to believe are correct as they now stand.

PLEASE post precise directions that we can follow to accurately determine what results you want to be produced based on the contents of input fields 1 and 2! If you haven't done that in the next 72 hours, this thread will be closed. (I am allowing 72 hours instead of 24 since we are rapidly approaching a weekend.)
