如何在Linux中查看日志文件并在查看时应用自定义过滤器？ [英] How can I view log files in Linux and apply custom filters while viewing?

问题描述

我需要通读Linux系统上的一些巨大的日志文件。日志里有很多混乱的东西。目前我正在做这样的事情：

  cat logfile.txt | grep -vIgnoreThis \ | IgnoreThat|减去
  

但是很麻烦 - 每次我想添加另一个过滤器时，我需要退出 less 并编辑命令行。有些过滤器比较复杂，可能是多行的。

我想通过日志读取过滤器，保存这些过滤器的地方。

有没有一个工具可以为我做这个？我不能安装新的软件，所以希望它已经被安装 - 例如，更少，vi，Python或Perl lib中的某些东西等。

更改生成日志生成更少的代码不是一个选项。

试试 multitail 工具 - 让您一次查看多重日志，我敢肯定它可以让您以交互方式应用正则表达式过滤器。

I need to read through some gigantic log files on a Linux system. There's a lot of clutter in the logs. At the moment I'm doing something like this:

cat logfile.txt | grep -v "IgnoreThis\|IgnoreThat" | less

But it's cumbersome -- every time I want to add another filter, I need to quit less and edit the command line. Some of the filters are relatively complicated and may be multi-line.

I'd like some way to apply filters as I am reading through the log, and a way to save these filters somewhere.

Is there a tool that can do this for me? I can't install new software so hopefully it's something that would already be installed -- e.g., less, vi, something in a Python or Perl lib, etc.

Changing the code that generates the log to generate less is not an option.

解决方案

Try the multitail tool - as well as letting you view multile logs at once, I'm pretty sure it lets you apply regex filters interactively.
