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. I don't want to run the app as root so how should I allow the app to read the file. The read function is actually built... (2 Replies)

console.handlers
console.handlers(5) System Administrator's Manual console.handlers(5)NAME
console.handlers - file specifying handlers of console lock and unlock events
DESCRIPTION
/etc/security/console.handlers determines which programs will be run when an user obtains the console lock at login time, and when the user
loses it on log out. It is read by the pam_console module.
The format is:
handler-filename lock|unlock [flag ...]
Where handler-filename is a name of the executable to be run, lock or unlock specifies on which event it should be run, and flags specify
how should pam_console call it.
Additionally there should be a line which specifies glob patterns of console devices.
The format of this line is: console-name consoledevs regex [regex ...]
Where console-name is a name of the console class - currently ignored - and regexes are regular expression patterns which specify the name
of the tty device. Only the first such line is consulted.
FLAGS
logfail
The pam_console module should log error to the system log if the return value of the handler is not zero or if the handler can not
be executed.
wait The pam_console should wait for the handler to exit before continuing.
setuid The handler should be executed with uid/gid of the user which obtained the console lock.
tty The handler will get a tty name as obtained from PAM as a parameter.
user The handler will get an user name as obtained from PAM as a parameter.
Anything else will be added directly as a parameter to the handler executable.
