Shell脚本，查找时差并遍历文件
我试图找出一个用户使用我的系统的时间，比如说3个用户A@x.com, B@x.com及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注销的时间一样 使用Grep和Awk命令，我可以得到如下结果Shell脚本，查找时差并遍历文件,shell,unix,time,scripting,Shell,Unix,Time,Scripting,我试图找出一个用户使用我的系统的时间，比如说3个用户A@x.com, B@x.com及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注销的时间一样 使用Grep和Awk命令，我可以得到如下结果 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 08:53

下面是一个使用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

示例文件中没有足够的数据生成有意义的结果。似乎用户可以打开多个会话，并且没有办法区分它们。因此，无法确定哪个“注销”事件对应哪个“登录”事件。找到识别会话的方法。接下来，约会会很好，而不仅仅是时间。这并不是那么简单。你也需要记录下你的疗程。例如，
