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(7D) Devices console(7D)NAME
console - STREAMS-based console interface
SYNOPSIS
/dev/console
DESCRIPTION
The file /dev/console refers to the system console device. /dev/console should be used for interactive purposes only. Use of /dev/console
for logging purposes is discouraged; syslog(3C) or msglog(7D) should be used instead.
The identity of this device depends on the EEPROM or NVRAM settings in effect at the most recent system reboot; by default, it is the
``workstation console'' device consisting of the workstation keyboard and frame buffer acting in concert to emulate an ASCII terminal (see
wscons(7D)).
Regardless of the system configuration, the console device provides asynchronous serial driver semantics so that, in conjunction with the
STREAMS line discipline module ldterm(7M), it supports the termio(7I) terminal interface.
SEE ALSO syslog(3C), termios(3C), ldterm(7M), termio(7I), msglog(7D), wscons(7D)NOTES
In contrast to pre-SunOS 5.0 releases, it is no longer possible to redirect I/O intended for /dev/console to some other device. Instead,
redirection now applies to the workstation console device using a revised programming interface (see wscons(7D)). Since the system console
is normally configured to be the work station console, the overall effect is largely unchanged from previous releases.
See wscons(7D) for detailed descriptions of control sequence syntax, ANSI control functions, control character functions and escape
sequence functions.
