PowerShell:过滤字符串列表 [英] PowerShell: filter string list

问题描述

这似乎是一件非常基本的事情，但我是 PowerShell 的新手，无法弄清楚这一点，也无法在网上找到示例...

This seems like a very basic thing to do, but I am new to PowerShell and can't figure this out or find an example online...

我正在尝试过滤字符串列表.此字符串列表是svn list"命令(存储库文件的 Subversion 列表)的结果，例如:

I am trying to filter a list of strings. This list of strings is the result of a "svn list" command (Subversion list of repository files), like:

svn list -R PATHTOREPOSITORY

我试过了

svn list -R PATHTOREPOSITORY | where {$_ -like "stringtomatch"}

这不起作用.我该如何解决?

and this does not work. How can I fix it?

推荐答案

您可以考虑使用 -match 而不是 -like.-Match 更强大(基于正则表达式)并且会像您最初期望的那样工作:

You might consider using -match instead of -like. -Match is more powerful (regex based) and will work like you were initially expecting:

svn list -R PATHTOREPOSITORY | where {$_ -match 'stringtomatch'}
