DHeisenberg - Thanks for suggestion. I wrote a program on similar patter in java and it is working perfectly fine.


RudiC - Thanks for your suggestion, Below one worked fine. (got some error in 2nd suggestion with live data)
Code:
awk     '/\*\*\*/               {if (CNT>4) for (i=1;i<=CNT;i++) print T[i]; CNT=0}
                                {T[++CNT]=$0}
         END                    {if (CNT>4) for (i=1;i<=CNT;i++) print T[i]}
        '  file

I have couple of question to understand it better and use it for other future requirement as well.

1. /\*\*\*/ is extracting the paragraph based on *** pattern and then based on number of line/rows count result is getting printed.
Instead of counting the number of lines if i want to check in this paragraph if any line starts with a number(.) then print it (kind of true or false logic) then how to do

2. I couldn't understand the logic of print 2 times (one before end and other after end with similar logic) even though final output is only once.

Thanks
