Rename-Item 没有替换文件名

Question

in following PowerShell code:

dir "D:\Test\New folder" | Rename-Item -NewName {$_.Name -replace 'PP&C Test (Bank), Ltd.','PP&C Test (Bank) Ltd.'}

what I am trying to do is replace all files within D:\Test\New folder that have PP&C Test (Bank), Ltd. in their filename with PP&C Test (Bank) Ltd. So basically just to remove the comma before Ltd.

When executing the script in PowerShell nothing gets renamed. Any idea why? I believe it is something to do with & and Brackets () as when I'm doing the same for filenames without those chars it works fine.

Thanks!

Answer 1

Or backslash the parens for the regex. I wonder if -replace should give a warning. The parens are used for grouping.

'PP&C Test (Bank), Ltd.' -replace 'PP&C Test \(Bank\), Ltd.',
                                  'PP&C Test (Bank) Ltd.'

PP&C Test (Bank) Ltd.

What escape() returns. I don't see why the spaces are escaped. . means any character.

[regex]::escape('PP&C Test (Bank), Ltd.')

PP&C\ Test\ \(Bank\),\ Ltd\.
