Number of elements, average value, min & max from a list of numbers using awk
Hi all,
I have a list of numbers. I need an awk command to find out the numbers of elements (number of numbers, sort to speak), the average value the min and max value. Reading the list only once, with awk.
Any ideas?
Thanks!
