Powershell 在 bat 文件中关闭控制台

Question

我有一个 bat 文件，可以规范几个文件夹音频。

我需要从 txt 文件中删除一些行，这些行将用于消除音频文件中的自定义标签。

我使用以下命令通过 bat 文件运行 powershell:\

"%systemroot%\system32\windowspowershell\v1.0\powershell.exe" -ExecutionPolicy Bypass -WindowStyle Hidden -Command "gci *.txt | foreach { (cat $_.fullname | ? { $_ -match 'METADATA|title|encoder' }) | set-content $_.fullname  }"

我使用-WindowStyle Hidden选项，这样powershell控制台就不会出现，但是当执行powershell命令时，bat控制台屏幕关闭并终止。

代码：

md "C:\Users\%username%\Desktop\Temp_normalizing_lufs"    ------> temp folder audio files being normalized   
pushd "%Userprofile%\Desktop\µudios LUFS"                 ------> folder with the original audio files

                                                                                                      __

如何运行 powershell 而不出现 powershell 控制台屏幕并保留 bat 文件控制台屏幕？

注意：
powershell 命令位于 SETLOCAL ENABLEDELAYEDEXPANSION 内执行的 for 循环内
