How can I direct messages from mac console.app to a log file?
I'm trying to complete a bash script to capture if an external webcam is active in a video conference session. Some users will switch the camera to the built-in MAC camera. When this happens I want to trigger a set of events.
Things tried: reviewed the console.app to look for patterns on when the switch occurs in a user test & discovered messages indicating when the facetime camera changes state. I found this
I thought I could simply grep these message from the console.app but it seems to be easier said than done. I thought i could find the msgs in one of the console report files but When I look at the various reports on the console, i'm not finding a report that contains the messages above. How can I direct messages from console.app to a log file versus manually copying and pasting the info from the console?or point me to a direction? Am I missing something?

What is the best practice to allow a 3rd party health monitoring app to read the messages file. Since messages is a system file and is owned by root the app cannot read the file.
