I am trying to get some lines from a file i did it with while-do-loop. since the files are huge it is taking much time. now i want to make it faster.
The requirement is the file will be having 1 million lines.
The format is like below.
What i know from the file is transnum in a set. I want to copy the ##transaction to till the next EOT for the particular transnum.
Also my requirement is from that file i want to copy only one set because my process will know only one transnum only.
So my output file will have only 10 to 15 lines (Only 1 transaction)
So please help me thanks.
