If you have some output lined up in columns, use awk to average the columns. Here’s some sample output (from a NetApp “toaster> stats show -p flexscale-access”)

    
# cat sample.txt

And the column averages:

# cat sample.txt | awk '{for (i=1;i<=NF;i++){a[i]+=$i;}} END {for (i=1;i<=NF;i++){printf "%.0f", a[i]/NR; printf "\t"};printf "\n"}'
73      5371    19      1241    81      10      4       43      0       0       0       0       405
#

Here awk loops through each field in a row, and adds the value to an array (a[i]) with the key being the field number. Then at the end, it takes the total, and divides by the number of rows (NR) and prints that (without decimals). It separates each field by a tab (\t) and after the end record prints a newline (\n).

You could make it print totals, as well as averages. You could also make it print out the original data, or a field header to know what each column represents...
