如何去掉不需要的线条？ while 循环？

2024-5-27 • tag-icon

我写了这段代码：

#!/bin/bash
filter(){

grep -Ev "INFO" /app/me/logs/$1

}

filter "$1" > /app/me/logs/${1}.filtered

cat /app/me/logs/${1}.filtered

所以它的作用是消除所有包含 INFO 一词的行。但同时它输出以下内容：

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

正如您所看到的，它工作正常，但顶部有一些不需要的行，不包含诸如“ERROR|FATAL|WARN”之类的单词。我不需要这些行，但同时我想要缩进的行及其前面的行。我希望它看起来像：

有什么帮助吗？谢谢，

要过滤掉所有行，直到以数字开头的第一行，请sed像这样使用 GNU：

sed '1,/^[0-9]/{/^[0-9]/!d}' logfile

该sed编辑脚本将/^[0-9]/!d“删除所有不以数字开头的行”，应用于从 1 到以数字 ( 1,/^[0-9]/) 开头的第一行（含）范围内的所有行。

要另外过滤掉任何 INFO 行：

sed -e '1,/^[0-9]/{/^[0-9]/!d}' -e '/INFO/d' logfile

所以你的脚本变成

#!/bin/bash

function filter {
    sed -e '1,/^[0-9]/{/^[0-9]/!d}' -e '/INFO/d'
}

filter <"/app/me/logs/$1" >"/app/me/logs/$1.filtered"

还要注意的是，我使filter函数与文件名或路径无关。它的唯一目的是获取输入流并输出过滤后的流。

为什么不是以下内容：

grep -Ev "INFO|SLF4J|201[0-9]
