I think you can use logger(1) in the action, like: action "logger -p kern.crit Loading firmware to cua$ttyname ; /usr/local/bin/gobi_loader etc etc" The 'kern.crit' should be a high enough priority to ensure it comes out on the console, but it depends on syslog.conf of course. If gobi_loader outputs a nice message it could be piped to logger(1) instead of putting the message in the command. -- Ian _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "[email protected]"
