Tip of the Day - freebsd-update
In FreeBSD 6.2 and later, the freebsd-update command allows you to update binaries of your base operating system.
It has four commands:
fetch - Inspects current system and downloads available needed updates.
install - After a fetch is run, this installs the downloaded updates.
rollback - Rollback the most recent update.
cron - Sleeps a random amount of time from 1 second to an hour, inspects the current system and downloads the available needed updates. If you have set an email address in the configuration file /etc/freebsd-update.conf it will email you with a list of needed updates (by default this email it sent to root locally). As its name depicts this is ideal for running freebsd-update in cron.
