I have a bat file that normalizes several folder audios.
I need to delete some lines from a txt file that will be used to eliminate custom tags in audio files.
I use the command below to run powershell via bat file:\
"%systemroot%\system32\windowspowershell\v1.0\powershell.exe" -ExecutionPolicy Bypass -WindowStyle Hidden -Command "gci *.txt | foreach { (cat $_.fullname | ? { $_ -match 'METADATA|title|encoder' }) | set-content $_.fullname }"I use the -WindowStyle Hidden option so that the powershell console does not appear, but when the powershell command is executed, the bat console screen closes and it is terminated.
Code:

Note:
The powershell command is inside a for loop that is executed inside SETLOCAL ENABLEDELAYEDEXPANSION
