问题描述

我正试图提出一个正则表达式表达式，该表达式匹配包含"mobile"但不包含"video"的所有字符串.我一直在努力在单个表达式中执行此操作，希望对您有所帮助./p>

I'm trying to come up with a single regex expression that matches all strings that contain "mobile" and do not contain "video" I've been struggling to do this in a single expression and would appreciate any help.

推荐答案

使用否定的前瞻断言:

^(?!.*video).*mobile

示例:

$ cat 1.txt
audio-mobile
mobile-video
mobile-video
video-mobile
videomobile
mobile
audio-mobile
audio

$ grep -P '^(?!.*video).*mobile' 1.txt
audio-mobile
mobile
audio-mobile
