如何查找缺少必需字符串的文件？ [英] How to find file that is missing a required string?

问题描述

在我的OS X命令行，我想找到所有以.per结尾的文件，它们缺少字符串'connection_id'。

On my OS X command line, I would like to find all files ending in .per that are missing the string 'connection_id'.

这样做。找到具有给定字符串的文件很容易，但是如果字符串丢失，我不知道如何做。

How do I go about doing this. Finding the files that have a given string is easy but am not sure how to do this if the string is missing.

谢谢！

推荐答案

find . -name '*.per' \! -exec grep -q 'connection_id' {} \; -print
