toprocess=$(top -b -n 1 | tail -n +8 | awk '{a[$NF]+=$10}END{for(k in a) print a[k],k}' | sort -gr | head -10)
cpunum=`cat /proc/cpuinfo | grep "processor" | sort | uniq | awk -F":" '{print $2}' | wc -l`
count=$(echo "$toprocess" | wc -l)
index=0

echo "CpuUsedTop10"
echo "$toprocess" | while read line; do
proname=`echo $line | awk '{print $2}'`
provaluetemp=`echo $line | awk '{print $1}'`
provalue=`echo "scale=2;${provaluetemp}/${cpunum}"|bc`
echo -n ' "'$proname'":"'$provalue'" '
index=`expr $index + 1`
if [ $index -lt $count ]; then
echo ','
fi
done

输出：
