-replace操作符有三种实现方式,其它文本操作符也类似地有三种实现方式,像-replace,-ireplace,-creplace,i前缀表示字符串大小写不敏感(insensitive),c前缀表示字符串大小写敏感(case sensitive)。 #下面的例子没有完成替换,因为当前大小写敏感: 第三类i前缀,表示大小写不敏感,和没有前缀的命令逻辑一样(PowerShell中默...
运算符实际上只能在其输入中找到最多一个匹配项,这是故意的,而-replace总是找到并替换所有匹配项。 对于PowerShell7.2.x,您需要直接使用底层的.NETAPI来查找多个匹配项,即[regex]::Matches()-matchall操作符来提供PowerShell-native实现——虽然该建议一直是green-lit,但还没有人加快实现它。 [regex]::Matches(...
$newText = $text.Replace($substring, $editedText) 通过这种方法,可以在PowerShell中编辑特定符号之间的文本。 当然,以上只是一种处理特定符号之间文本的示例方法。实际上,PowerShell提供了丰富的字符串处理和文本编辑功能,可以根据具体的需求采用不同的方法和技术。 腾讯云相关产品推荐:在腾讯云上进行云计算开发和运维...

RegEx is used widely in PowerShell: -split, -replace, Select-String, etc. RegEx excels at parsing string patterns out of text with speed. Take some time to learn it today (Get-Help about_Regular_Expressions). The new Convert-String and ConvertFrom-String cmdlets were i...
I really wish Microsoft actually supported the PCRE regex code. Sadly, it does not. Your request (pretty easily handled in other languages) could be done like this: Copy $s -replace '^([a-z])(.+)([a-z])(\d\d)$', '\U$1\E$2\U$3\E$4' Where "/U" says to ...
