You do not need to be running a window system, such as the OpenWindows environment, for the sys-suspend shell command to work. You also do not need to login as superuser.
At the prompt, type:
example% /usr/openwin/bin/sys-suspend |
The Suspend confirmation pop-up window is displayed, as shown in Figure 3-8. If a window system is not running, the command executes without displaying the confirmation pop-up window.
Click Suspend.
Wait for the system to power off.
Power off all external units.
External devices include disk drives, printers, or other serial or parallel peripherals. See the manual supplied with the external device for instructions.
