ugen.sh

Run this in the directory where your *.log files are :)
or ugen.sh | grep -v " 0 hrs"
For me 192\.168\. matches my solo mining runs/test runs which I ignored for this

#!/bin/sh
#
numbers()
{
 m2="Runtime:|Pool:|] Average hashrate:"
 egrep "Utility \(accepted shares / min\)|$m2" "$1"
}
#
value()
{
 echo "$1" | grep "$2" | cut -d':' -f4-
}
#
nums()
{
 tr -dc "0123456789."
}
#
process()
{
 data="`numbers "$1" 2> /dev/null`"
 if [ "$data" ] ; then
    haspool="`echo "$data" | grep "Pool:" | grep -v 192\.168\.`"
    if [ "$haspool" ] ; then
        hasrun="`echo "$data" | grep "Runtime:"`"
        if [ "$hasrun" ] ; then

            utility="`value "$data" Utility | nums`"

            echo "$1,$runtime,$utility,$hash"
