HP-UX version 11.00.03 Starting and Stopping the System 3-25
Changing to Single-User State
To change to a single-user state, do the following:
1. Change to the / (root) directory. To do this, enter
cd /
2. Shut down the system. To do this, enter
shutdown
The system prompts you to send a message informing users how much time
they have to end their sessions and when to log off.
3. At the prompt for sending a message, enter y.
4. Enter a message.
5. When you finish entering the message, press
<Return> and then <Ctrl>-<D>.
The system shuts down to a single-user state after the default 60-second grace
period.
CAUTION
Do not run shutdown from a remote system. You will be logged out and
control will be returned to the system console. For more information, see
the shutdown(1M) man page.
Broadcasting a Message to Users
You can use the wall command to send a message to all users that are logged on
before you shut it down. For more information, see the wall(1M) man page.
Rebooting the System
When you finish performing necessary system administration tasks, you can boot
the system without turning off any equipment.
■ If the system is in single-user state (run-level s), enter
reboot
The system returns a series of messages similar to the following:
Shutdown at 16:47 (in 0 minutes)
