如何将两个搜索词与"grep"组合(和) [英] How to combine two search words with "grep" (AND)

问题描述

使用grep，我可以在本地文件夹的50个文件中找到一个单词，即:

With grep, I can find a word within 50 files in a local folder, i.e.:

grep -i "hello" *.html

但是如何查找包含两个单词的文件?示例:我想查找所有包含单词"hello"和单词"peter"的文件.如何合并两个grep?

But how can I find files that contain TWO words? Example: I would like to find all files, that contain Word "hello" AND word "peter". How can I combine two grep's?

推荐答案

要查看包含两个单词的文件(可能在不同的行上)，请使用-l和xargs:

To see the files containing both words (possibly on different lines), use -l and xargs:

grep -il "hello" *.html | xargs grep -il "peter"

修改

如果文件名中包含空格，则我们需要多加注意.为此，我们可以对grep和xargs使用特殊选项:

If your files have spaces in their names, then we need to be a little more careful. For that we can use special options to grep and xargs:

grep -ilZ "hello" *.html | xargs -0 grep -il "peter"
