To reboot or shutdown a FreeBSD or other BSD system, you can use the shutdown command. The shutdown command allows you to reboot or shut down the system in a controlled manner, giving users time to save their work and allowing system processes to be terminated gracefully.
To reboot the system, you can use the -r option:
shutdown -r now
This will reboot the system immediately.
To shut down the system, you can use the -p option:
shutdown -p now
This will shut down the system immediately.
You can also specify a delay before the reboot or shutdown occurs by using the -h option followed by the number of minutes to wait. For example:
shutdown -r +10
This will reboot the system in 10 minutes.
It's a good idea to use the shutdown command instead of just turning off the power, as it allows the system to properly terminate processes and clean up before shutting down.
