求和与平均值

cat client.log | grep 耗时 | awk '{print $NF}' | awk -F'耗时' '{sum+=$NF;count+=1} END{print "SUM="sum,"AVG="sum/count}'

求最小值

cat client.log | grep 耗时 | awk '{print $NF}' | awk -F'耗时' 'BEGIN {min = 9999999999}{if ($NF+0 < min+0) min=$NF} END {print "MIN="min}'

求最大值

cat client.log | grep 耗时 | awk '{print $NF}' | awk -F'耗时' 'BEGIN {max = 0}{if ($NF+0 > max+0) max=$NF} END {print "MAX="max}'
