tcl.power-off
Performs orderly system shutdown sequence.
Syntax
power-off {(u}
Description
brings the system to an 'orderly shutdown' by logging off all users, flushing memory to disk, and parking the disk heads prior to halting the system.
This is used prior to system shutdown to ensure that all work spaces are returned to overflow and all updated frames in memory are written to disk. 'power-off' puts the machine in a HALT state.
The status of the Spooler is displayed and an option to continue is offered . If 'y' is entered to continue, any user still logged on is logged off, all process work spaces are released, all printers are stopped, and all updated memory frames are written to disk. The system is shut down.
If the 'u' option is not specified and any port, other than the port executing 'power-off', is logged on, the system prompts for each port to be logged off.
If the port is not logged off by the time the 'power-off' reaches its final phase, the port is automatically logged off.
Options
u Unconditionally logs all ports off.
Example

and the process stops, and returns to TCL:

If the response to the question is 'y', it attempts to log the port

This question is repeated for all ports which are still active.

and the process stops, and returns to TCL:

If the response to the question is 'y', the following messages appear:
