英文:
Parse a log file remembering last run
问题
我有一个简单的脚本，它打开一个文件（日志文件），并解析其中的特定日志条目/关键字。对于每个匹配的条目，它会触发一个警报。
我想要解决的问题是，我希望修改脚本，以便在上次运行时记住已发送的警报，这样如果脚本重新运行，它就不会为已发送的警报再次发送警报。
编程语言是Golang，有哪些有效的方法可以实现这个功能？使用数据库似乎有点过头了，但我不知道还有其他什么选择？
英文:
I have a simple script that opens a file (log file), parses through it looking for specific log entries/keywords and for each entry that matches it triggers an alert.
The problem that I am trying to solve is that I would like to modify the script to remember the alarms that were already sent when it was last run, so that if the script re-runs it won't keep sending an alert for previously sent alerts.
The coding language is Golang, what are the a valid approach to do this? A database sounds like overkill, but I don't know what other alternatives are out there?

这取决于日志文件的性质：服务器日志（经典）还是事务日志。即使假设是前者，也要考虑其日志管理（长期保留、轮换等）。
假设是追加数据而不是覆盖的经典日志文件，一个简单的方法是在一个文件中生成找到警报的行。在下一次运行时，如果该行与存储在特殊的“标志”文件中的行匹配，那么警报将不会再次发送。
英文:
It depends on the nature of the log file: server log (classic) or transation log.
Even assuming the former, it depends on its Log Management (long term retention, rotation, ...)
Assuming a classic log files whose data are appended (not overwritten), a simple approach would be to generate in a file the line where the alert is found.
At the next run, if that line matches one stored in that special "flag" file, the alert would not be sent again.
