[*NIX] audio file conversion using ffmpeg - deletes after conversion

convert.sh

#!/bin/bash
find . -name "*.wav" | xargs -I % sh -c 'ffmpeg -hide_banner -y -i "%" -acodec libvorbis -f ogg "%_"; rm "%";' && find . -name "*.mp3" | xargs -I % sh -c 'ffmpeg -hide_banner -y -i "%" -acodec libmp3lame -f mp3 "%_"; rm "%";'

Using this script left me with all the files renamed with the _ at the end. So I asked ChatGTP for some help. Here's what he/she/it said about the script:

Problematic Part:
"%_":
The output file name "%_" is intended to modify the file name but doesn't work as expected. Instead of producing a properly named .ogg file, this results in a file with the original name plus an underscore (.wav_ or .mp3_).
The script then deletes the original file, leaving you with the renamed file (.wav_ or .mp3_), which is still in the original format (not converted to .ogg or a new .mp3).
Why .wav Files Are Renamed but Not Converted:
The incorrect naming ("%_") causes the file to simply be renamed rather than properly converted to the new format. Since ffmpeg does not recognize the underscore as a file extension, it doesn't change the format.

Thought I let you all know what issue I ran in to. I'm not specifically looking for a solution. Since my knowledge on scripts is very limited, I decided to copy the files to my desktop computer and used a .bat file to achieve our goal. Then I copied everything back to the server. This workaround did the job for me.
