Thanks Don- Will check the performance and update you.

I am also looking to write in one line code something like below..

Code:
cat test2.tlog | awk 'BEGIN { record_type=${record%"${record#????}"}; 
if (record_type == 1111) {a1=100; a2=0; a3=0; a4=0; a5=0; a6=0; a7=0;a8=0; a9=0} 
if (record_type == 2222) {a2=$(( a2 + 1 )); a3=$(( a3 + 2))} 
...
...
else printf $line_no$a1....$9;
printf $line_no$a1....$9
}' >> test1_all_data.log


Kindly let me know if you have any suggestions on this.
