Apologies in case i am disturbing you with my posts.
I am not much good with awk scripting but I do shell scripting and try to learn more with the issues i come across
But sincerely i need to know work around for this query.
I tried the below code, but it is not working as per my expectation.
It is working when column 2 contains unique value in every row, but if row 2 and row 5 contains same value, it prints "error".
Request if you can help to improve.
I need to have file suppose that contains duplicate values in column 1 then against those duplicate value in column 2 there should be unique values
In above sample file.
There wont' be 2 line per document number, there can be any number of duplicate values, it can be more than 5 or even 50
Yes, there should be non-identical number in column2(Line number) per Document number(column1) and there is no limit on number, they just has to be non duplicate.
if column 1 contain duplicate values in row then corresponding to those duplicate values in row column 2 should contain non duplicate values

I was reading this thread. It looks like a simpler way to say this is to only keep uniq lines based on field or column 1.
