使用 powershell 查找与两个单独的正则表达式匹配的文件 [英] Using powershell to find files that match two seperate regular expressions

问题描述

我想找到任何可以匹配两个正则表达式的文件，例如所有文件至少具有bat、hat、cat 以及词名词.这将是可以匹配正则表达式 [bhc]at 和 noun 的任何文件.

I want to find any file that can match two regular expressions, for example all files that have at least one of bat, hat, cat as well as the word noun. That would be any file that can match both regular expressions [bhc]at and noun.

select-string 的正则表达式参数似乎只能逐行工作.似乎您可以传入以逗号分隔的多个模式(select-string -pattern "[bhc]at","noun")，但它匹配一个，而不是两个.

The regex parameter to select-string only seems to work on a line-by-line basis. It seems you can pass in multiple patterns delimited by commas (select-string -pattern "[bhc]at","noun") but it matches either, rather than both.

推荐答案

将@mjolinor 的单个 get-content 与@JNK 的优化过滤合并提供:

Merging @mjolinor's single get-content with @JNK's optimised filtering gives:

dir | ?{ [string](gc $_) | ?{$_ -match "[bhc]at"} | ?{$_ -match "noun"} }

如果您不介意重复，您可以通过管道将结果选择字符串以查看这些匹配的上下文:

If you don't mind the repetition, you can pipe the results to select string to view the contexts of these matches:

    | select-string -pattern "[bhc]at","noun" -allmatches
