      update      - run freebsd-update in each jail
      audit       - run 'pkg audit' in each jail
      mergemaster - run mergemaster in each jail
      versions    - report versions of each runnning jail

      selfupgrade - upgrade this script

Enter each jail

jailmanage all

Upgrade FreeBSD version in every jail

jailmanage update

This runs a command like this command for each jail:

freebsd-update -b /jails/dns -f /jails/dns/etc/freebsd-update.conf install

If jailmanage detects that the jail is running an older major version of FreeBSD than the host (ex: host is running 10.2 and jail is running 10.1), then jailmanage will perform a binary upgrade of FreeBSD using these commands:

freebsd-update -b /jails/dns -f /jails/dns/etc/freebsd-update.conf -r 10.2-RELEASE upgrade install
freebsd-update -b /jails/dns -f /jails/dns/etc/freebsd-update.conf install
freebsd-update -b /jails/dns -f /jails/dns/etc/freebsd-update.conf install

Delete caches

jailmanage cleanup

This command empties /var/cache/pkg and /var/db/freebsd-update in every jail.
