I would like to find the maximum value in the column no. 5 (Determine) for every 10 rows and then print the corresponding entire row. For eg. in the first 10 rows, the maximum value in the 5th column is '1.1824' and the corresponding entire row is "10_M62 6: 3.0561 405.69 1.1824". I want to find the maximum value in the 5th column for every 10 rows and then print the entire column like show above.

I tried the following command, it works for first 30 rows after which it gives wrong answers. I am not sure what I am missing. Kindly help me.

awk 'm<$10{m=$10;n=$5" "$2$3 $4" "$6" "$7" "$8" "$9} !((NR+2)%10){print $1,n,m;m=n=""}'

Please let me know if I am not clear. I have given the sample list below.

This will work using any awk in any shell on every UNIX box even if your input values are all negative and/or your input is not an exact multiple of 10 lines and no matter how many blank lines are between your header line and your data:

$ cat tst.awk
NR==1 { print; next }
!NF { next }
(++numLines) % 10 == 1 {
    printf "%s", maxLine
    maxVal = $5
    maxLine = ""
}
$5 >= maxVal {
    maxVal = $5
    maxLine = $0 ORS
}
END { printf "%s", maxLine }

.

$ awk -f tst.awk file
Name      No.           Value1   Value2   Determine
10_M62    6:            3.0561   405.69   1.1824
11_M63    2:            2.3544   526.62   1.8099
