How to Pass Variables and Execute the Shell Script

[ying]

Hi, All~

I want to create a macro using ffmpeg to convert videos to mp3 audio files.

I built my macro upon the post Run Single Command on Finder Selection - Macro Library - Keyboard Maestro Discourse

Below is the screenshot of the macro

When I ran the macro, the notification said:

So I tried to run the command directly in iTerm2, and it worked. See screenshots below.

When I ran ``which ffmpeg`` it showed as ``/usr/local/bin/ffmpeg``

I wonder what I did wrong. Any feedback or suggestions would be greatly appreciated. Thanks!

Ah....
Never mind! I think I figured it out.

I find this post: Can I commit files from Git from KM? - Questions & Suggestions - Keyboard Maestro Discourse

So I added
export PATH=/usr/local/bin:$PATH;
at the beginning of the script, and it now works!

In the Execute Shell Script action that failed, if you select Help from the gear menu, you will be taken to the Execute a Shell Script action documentation. In the Path in Shell Scripts section is the details of the solution.
