您好，我需要从文件中提取：

Hi, I need to extract from the file:

first
second
third

使用grep命令，下面一行：

using the grep command, the following line:

second
third

应该如何grep命令样子？

How should the grep command look like?

推荐答案

而不是的grep ，您可以用 pcregrep 支持多行模式

Instead of grep, you can use pcregrep which supports multiline patterns

pcregrep -M 'second\nthird' file

-M 允许模式来匹配多个行。

-M allows the pattern to match more than one line.
