用grep在一行中匹配两个字符串 [英] Match two strings in one line with grep

问题描述

我正在尝试使用grep来匹配包含两个不同字符串的行.我已经尝试了以下操作，但这与包含 string1 或 string2 的行匹配，这不是我想要的.

I am trying to use grep to match lines that contain two different strings. I have tried the following but this matches lines that contain either string1 or string2 which not what I want.

grep 'string1\|string2' filename

那么我如何只将同时包含两个字符串的行与grep匹配?

So how do I match with grep only the lines that contain both strings?

推荐答案

您可以使用grep 'string1' filename | grep 'string2'

或者，grep 'string1.*string2\|string2.*string1' filename
