Get daily averages from sar

Is there a way to just display a given days averages using sar. I currently do something like the following: sar -u -s 00:00:00 -e 23:59:59 -f /var/log/sysstat/sa10 And just take the last (average) line to add to a report. But it would be nice and easy to just gen my report if I could pass an argument to just spit-out the average. I could not find such an option in the sar documentation. So, unless I am missing it, I am guessing the option is no. However, It's very possible I'm missing it or there might be another tool other than sar that might expose this functionality.
