powershell - 使用PowerShell重命名具有多个句点的文件

Question

我的文件夹中有一些文件，希望删除句点并替换为另一个符号。

我的文件命名如下:

filename 12.31.15.pdffilename 03.18.14.pdffilename 02.17.15.pdf

I have to run two PowerShell scripts, one for changing the symbols and the other one for renaming files with back to the .pdf extenstion.

Is there a way to use one command for this?

I'm using the commands below:

Get-ChildItem -Filter "*.pdf" | Rename-Item -NewName {$_.Name.Replace(".", "-")}
Get-ChildItem -Filter "*-pdf" | Rename-Item -NewName {$_.Name.Replace("-pdf", ".pdf")}

Answer 1

在基本名称上进行替换并添加扩展名:

... | Rename-Item -NewName { $_.Basename.Replace('.', '-') + $_.Extension }
