Taking a average of a column of numbers
Hey all, I am relatively poor at programming and unfortunately don't have time to read about programming at this current moment.

I wanted to be able to run a simple command to read a column of numbers in a file and give me the average of those numbers. In addition if I could specify the starting and ending line of the numbers to take an average of that would be great. I assume I would use some form of awk but like I said I don't have a lot of time to research this right now. I greatly appreciate any help.

Thank you

Thank you very much that was perfect, I just needed the skeleton. I was able to edit this to work exactly how I needed it to. Thank you again.
