查找用下划线或破折号连接的小写字母序列的脚本

Question

我是 powershell 写脚本的新手，尤其对正则表达式了解甚少，请帮忙实现一下。

例子：

PS > .\test.ps1 "A Balrog is a powerful fictional monster in Middle-earth."
return: Middle-earth

或者

PS >.\test.ps1 "The symbol underscore, also called low_line or low dash."
return: low_line

当然，我尝试找到解决这个问题的方法，以下是我的解决方案：

#$data = $args[0]

$p = '\w*[-_]\w*'

Select-String -Path .\content.txt -Pattern $p | % {$_ -match $p; $matches.Value}

Write-Output $matches

============================================== 更新：找到解决方案

Answer 1

$data = $args[0]

$pattern = '\w*[-_]\w*'

$matches = [regex]::Matches($data, $pattern).Value

Write-Output $matches
