我希望所有记录直到文件末尾，这些记录大于unix中的给定日期

标签： unix

我希望所有记录直到日志文件的末尾，这些记录大于给定日期... 假设给定日期是2015年12月14日22:00:03那么我希望日志文件中的所有行直到第一次出现大于此日期时结束。

ex：awk'{if（$ 0＆gt;“Tue Dec 15 08:00:00 2015”）print}'file.out

  • 只打印大于日期的行，但我希望匹配后的所有行直到文件结尾..

请注意 1.我不能使用正则表达式，因为我不知道该日期的日志文件中是否存在条目，即H：M：S所以我必须使用大于日期的功能。

  1. 日期不存在于lg文件的每一行。它介于两者之间，但在新行

    2. 请帮助

    示例日志文件:::

You have following choices to free up space from flash recovery area:
1. Consider changing RMAN RETENTION POLICY. If you are using Data Guard,

2. Back up files to tertiary device such as tape using RMAN
   BACKUP RECOVERY AREA command.
3. Add disk space and increase db_recovery_file_dest_size parameter to

4. Delete unnecessary files using RMAN DELETE command. If an operating

带有硬编码日期时间和输入文件的简单python 2解析器。使用您给定的日志进行测试。它有足够的优化空间，但我认为这是一个开始。

#/usr/bin/env python

import re
from datetime import datetime

# year, month, day, hour, minute
filter_from = datetime(2015, 12, 13, 23, 40)

with open("tmp.log") as log:
    match = False
    for line in log:
        if (match):
            print line
        else:
            candidate = re.match(r'[A-Z][a-z][a-z] [A-Z][a-z][a-z] \d\d \d\d:\d\d:\d\d \d\d\d\d', line)
            if candidate:
                parsed_date = datetime.strptime(candidate.group(0), "%a %b %d %X %Y")
                if parsed_date > filter_from:
                     match = True
                     print line
