@Yoda : that might be dangerous as might remove single lines that could be duplicates of other records. I have to admit this is a remote possibility. Still, you can make it safer adding sth like RS="\n\n\n" to your proposal

The occurrences are just random number of times.. all I need is just print the 1st occurrence of the start pattern match..

awk '!A[$0]++' RS="\n\n\n" test.txt # works great .
Have a good day
