       sys-suspend - suspend or shutdown the system and power off

       /usr/bin/sys-suspend [-fnxh][-d displayname]

       sys-suspend provides options to suspend or shutdown the whole system.

       A  system  can  be suspended to conserve power or to prepare the system for transport. The
       suspend should not be used when performing any hardware reconfiguration or replacement.

       In case of suspend, the current system state is preserved either by keeping memory powered
       (Suspend to RAM), or by saving the state to non-volatile storage (Suspend to Disk) until a
       resume operation is performed by power on or a wake-up event.

       On a resume in the windows environment, the system brings up  lockscreen  to  ensure  that
       only  the  authorized  person  has access to the system. In a non-windows environment, the
       user is prompted for password.

       It is possible that when devices or processes are performing critical  or  time	sensitive
       operations  (such  as real time operations) the system fails to suspend. When this occurs,
       the system remains in its current running state. Messages reporting the failure	are  dis-
       played on the console or system log. Once the system is successfully suspended, the resume
       operation always succeed barring external influences such as hardware  reconfiguration  or
       the like.

       In case of shutdown, the system responds as if poweroff(1M) was performed.

       This  command  enforces	the  solaris.system.power.suspend.  authorizations.  On a default
       install these are associated with the console user. Other  users  need  to  include  these
       authorizations or include the Suspend profile.

       The following operands are supported:

       -d displayname	 Connect to the X server specified by displayname.

       -f    Force suspend. Causes a poweroff(1M) to occur if the suspend fails. System state are
	     not be saved, and a normal boot follows.

       -h    Change the default from suspend to shutdown.

       -n    Do not display messages or request user intervention.

       -x    Disable lockscreen. This flag disables the execution of lockscreen at resume time.
