25 0.4
........

........



I want to get output as

If there are no missing values in file 2 you could try:
Code:
awk 'NR==FNR{A[$1]=$2; next}{t=0; for(i=$2; i<=$3; i++)t+=A[i]; print $0, t/($3-$2+1)}' file2 file1

Unfortunately if i am running this its showing that the process is been killed i tried with the small dataset it gives the desired output.

Are you saying it works correctly for a small file, but does not finish (crashes) with a large file?

Old 04-22-2013
Ya exactly dividing the file would be more hectic due do my large data set

Old 04-22-2013
I'm not suggesting you divide the file. I'm asking if it crashes on the large file. If yes, how long does it run before crashing? And is there any error message? Copy and paste what's going on so we can see. Smilie
