You could create an alias with all the names, for instance, and mail to that. If they're in /etc/passwd, then cat /etc/passwd|cut -d: -f1|while read user do mail -s "Downtime Scheduled" $user < message.txt done would do it (put your message in message.txt). You'd also send mail to the non-user users like daemon, but you'd cover everybody. If you're using NIS, then "ypcat passwd" instead of "cat /etc/passwd".
