The following seems to do what you want:

awk -v f1=first.txt -v f2=second.txt '
(NR - 1) % 12 <= 8 {print > f1}
(NR - 1) % 12 == 0 || (NR - 1) % 12 > 8 {print > f2}
' file1.txt

but the results don't quite match your sample files because you have different numbers of trailing spaces between lines 1 and 13 in file1.txt and what you said you want to see on lines 1 and 5 of the output to be placed in second.txt.

In the below line, why it was not considered as 94 ?

 
94yr 48yr  4hr  erhj  reh

Hi itkamaraj,
If you look back at message #1 in this thread, you'll see that the line you asked about is shown as:

94yr 48yr  4hr  erhj  reh

rather than

94yr 48yr  4hr  erhj  reh

(the 9 is in red, but the 4 is in black).

I assumed that the intent was that the numbers in red are line numbers (in repeating sets numbered from 1 through 12) used for discussion, but not actually present in the input file. Your code sample assumes that these numbers in red actually appear in the file.

i150371485 needs to clarify the intent for us to find out which assumption was correct.
