Python代码如下所示：

#!/usr/bin/env python
# -*- coding:utf-8 -*-
__author__ = '40kuai'
li = [0 for i in range(1440)]
with open('/root/access_log.2017-11-06-00_00_00') as file:
    for line in file:
        hour = line.split(':')[1]
        mins = line.split(':')[2]
        haha =  int(hour)*60+int(mins)
        li[haha] +=1


for index,i in enumerate(li):
    try:
        a,b=divmod(index,60)
        print '%s:%s' % (a, b), i
    except ZeroDivisionError as e:
        print '00:00', i

又用Shell编了一个简单Shell脚本，脚本如下：

#!/bin/bash
for i in {00..23} ;do
  for j in {00..59} ;do 
    echo $i:$j  `awk '{print $4}' /root/access_log.2017-11-06-00_00_00|awk -F ':' '{print $2$3}'|grep $i$j|wc -l`>>/lines.txt
  done
done

两个脚本的效率差别很大。。。哪位大神可以帮忙看看能不能优化一下Shell脚本，Shell主要问题为循环读文件进行过滤
