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
