我试图找到用户使用我的系统多长时间，有3个用户A @ x.com，B @ x.com和C@x.com。我有session.log，其中所有记录都存在，就像一个人登录然后登出。
使用Grep和Awk命令我可以得到像
这样的结果07:50:00:942 A@x.com Login
07:50:19:612 A@x.com Login
07:52:14:697 A@x.com Logout
08:12:41:591 A@x.com Login

这一切都在result.log文件中。
现在我想终于找到A，B和C使用系统的时间。
请指导我如何遍历此文件以提取时间列，同时还要查找登录时间和退出时间。
请建议！
为了更好地理解，我正在分享我为解压result.log -
而编写的代码#! bin/bash

答案 0 :(得分：0)
以下是使用Python的解决方案：
import collections
import datetime
import sys
login = {} # { username : logintime }
state = collections.defaultdict(int) # { username : refcount }
def parse_time(text):
"""Return timedelta since midnight given input as hh:mm:ss:fff."""
hh, mm, ss, fff = text.split(':')
total_seconds = int(hh)*3600 + int(mm)*60 + int(ss) + int(fff)/1000
return datetime.timedelta(seconds=total_seconds)
for line in open(sys.argv[1]):
tokens = line.split()
if tokens:
time, user, action = tokens
if action == 'Login':
state[user] += 1
if state[user] == 1:
login[user] = time
elif action == 'Logout' and state[user] > 0: # ignore redundant logouts
state[user] -= 1
if state[user] == 0:
duration = parse_time(time) - parse_time(login[user])
print user, "logged in at", login[user], "for", duration
来自OP的样本输入的输出：
