Summary:

On Mojave 10.14 (18A389) the screencapture command incorrectly throws an error when I try to record my screen with audio.

Steps to Reproduce:

1. Open Terminal
2. Try to run the screencapture command configured like so: 

screencapture -v -A ~/Desktop/out.mov

Expected Results:

My screen should begin recording video with audio included

Actual Results:

I get this error: "screencapture: illegal option -- A"

Even though the command manual shows "-A" as a valid option:

"  -A<id>    captures audio during a video recording using default input. Optional specify the id of the audio source"
