i have the following three statements in  a perl script

as you can see they compute avg, min and max from the second column of a two digit column file...

can i somehow combine the statements into just 1 seems a bit stretched to ghave 3 statements processing the file 3 times....

$a=`nawk 'NR==1{k=0;Sum=0}{k=k+1; Sum=Sum+$2}END{print  k "  Records found" }' d
$avg = `nawk 'NR==1{k=0;Sum=0}{k=k+1; Sum=Sum+$2}END{print "<b>Avg</b> = "Sum/k
}' data`;
$min = `awk 'min=="" || $2 < min {min=$2} END{ print min}' data`;
$max = `awk 'max=="" || $2 > max {max=$2} END{ print max}' data`;

the file looks like this:

11111     8.77777
22222     98.0000

and so on
