C
结尾，文件类型为
f
（标准文件，而不是目录，目录的类型符号为
d
）。你应该会看到输出
许多匹配的文件名。下面，我们将这些文件通过管道传递给
grep
命令：
find . -name "*.txt" -type f | xargs grep neat
这里我们让
bash
做的是，“找到与上面相同的文本文件，然后在这些文件中搜索单词
neat
”。我们用到了
xargs
命令（
https://en.wikipedia.org/wiki/Xargs
），这样才能将
find
的输
出通过管道正确地传递给
grep
。不是所有的管道操作都需要用到
xargs
，但当
find
命令的
输出结果不完全相同时，这一命令十分有用。
你已经学会搜索和查找的一些实用技巧，特别是你要处理的代码和项目越来越庞大、越来
越复杂时，这些技巧尤其有用。关于这一话题，我们还为你提供了更多资源和阅读材料。
