Solaris 10 Zones

zonecfg -z ZONE_NAME info
Display configuration information for a Zone; useful when determining if a zone is Sparse/Full root.

zonecfg -z ZONE_NAME verify
Validate that the configuration for the zone is valid.

zoneadm list -vc
Display the current state of all the zones running on a system

zlogin ZONE_NAME = Login as root
zlogin -C ZONE_NAME = Login as root console
zlogin -S ZONE_NAME = Login safemode as root

zoneadm list|sed 1d|xargs -I {} zlogin -z {} "svcadm disable svc:/system/cron:default"
Good one-liner to run a command on all running non-global zones. In this example I am disabling CRON.
