Convert audio file to m4a through ffmpeg + shell script

[frank]

Hi KM community,

I was trying to do make a macro to batch convert multiple .wav file into m4a using ffmpeg but don't know why it didn't work.
I tried to run it in terminal and it execute perfectly.

Here is what I got in shell script

In that case you probably need to provide the full path the ffmpeg in the shell script.
KM Shell Scripts are NOT aware of your Terminal path or environment.
