Hi,
I need to compare 2 files using awk, file1 & file2 line by line. Field 5 in everyline of file1 should be compared in whole file2 & if match is found then print that line in file2 & then print next 20 lines in file2. Continue the same process for all lines in file1. Can some one try this & send the script to me at the earliest.
Thx.

Try something like this...

awk -F: 'NR==FNR {a[$5]; next}

{
$5 in a
print $0
getline

for(i=1;i<=20;i++) {
print
getline
}
}' f1 f2

Can you provide your email ID?
I will provide you 2 files..you can test your code and then send that to me. I am novice on awk & Every time i run suggested code, i am not getting any o/p.
