grep日志文件大于时间戳 [英] Grep log file greater than time stamp

问题描述

我有一个unix日志文件（application.log），它有起始日志和时间戳记。我需要在这个日志文件中搜索发送模式的时间大于时间2014-03-20 14:05:54。

I have a unix log file(application.log), that has logs with timestamp at the starting. I need to search for a pattern "sent" in this log file greater than time 2014-03-20 14:05:54.

2014-03-20 14:05:54,038 [NfxAgent....
2014-03-20 14:05:54,164 [NfxAgent....
2014-03-20 14:05:54,298 [NfxAgent....
2014-03-20 14:05:54,414 [NfxAgent....
2014-03-20 14:05:54,787 [NfxAgent....

推荐答案

我为测试数据添加了2条记录，以确保它真的有效：

I added 2 more records to the test data to ensure this is really working:

2014-03-19 14:05:53,999 [NfxAgent....
2014-03-20 14:05:53,164 [NfxAgent....

但我不认为你可以使用 grep 来达到这个目的。这是一个awk解决方案：

But I don't think you can use grep for this. Here is an awk solution:

$ grep sent  grepTest_20140321.txt|  awk '$0 > "2014-03-20 14:05:54"' 
2014-03-20 14:05:54,038 [NfxAgent....
2014-03-20 14:05:54,164 [NfxAgent....
2014-03-20 14:05:54,298 [NfxAgent....
2014-03-20 14:05:54,414 [NfxAgent....
2014-03-20 14:05:54,787 [NfxAgent....

编辑

如果我们需要使用相同格式指定结束时间，例如2014-03-21 10:04:140018？

"What if we need to specify the end time in the same format like 2014-03-21 10:04:14,018?"

我已经添加了三行测试数据来确认第二种情况：

And I've added 3 lines of test data to confirm the 2nd case:

2014-03-21 10:04:14,017 [NfxAgent....
2014-03-21 10:04:14,018 [NfxAgent....
2014-03-22 10:04:14,999 [NfxAgent....

结果显示您指定范围内的一条新记录。

Result shows one new record in the range you've specified.

2014-03-20 14:05:54,038 [NfxAgent....
2014-03-20 14:05:54,164 [NfxAgent....
2014-03-20 14:05:54,298 [NfxAgent....
2014-03-20 14:05:54,414 [NfxAgent....
2014-03-20 14:05:54,787 [NfxAgent....
2014-03-21 10:04:14,017 [NfxAgent....
