If you don’t want users to be notified or send custom shutdown messages, the you can add command options..
To prevent user notifications, run the reboot command with the –no-wall option..
sudo systemctl --no-wall reboot
The command above will shutdown the system without notifying any logged in users..
If you want to send custom message that the system is going down for a particular reason, run the command with the –message=” “ option:
sudo systemctl --message="System Maintenance" reboot
The commands above will display a message to all logged in users that the system is going reboot with a message that reads:
This is how to reboot Ubuntu
Option 2: Reboot | Restart using the shutdown Command
You can accomplish the same goals as above using the shutdown command… The shutdown command is the oldest way to shutdown or reboot Linux systems, including Ubuntu..
To reboot Ubuntu using the shutdown command, run the command with the -r option:
sudo shutdown -r
The -r option tells the command to reboot….
By default the system will reboot after 1 minute.. However, if can use other command options to specified how long to wait before going to reboot the system..
For example, to reboot the system after 5 mins, run the commands below:
sudo shutdown -r +5
That will reboot the system after 5 mins…
To specify an exact time to reboot, use the format hh:mm for hours and minutes..
Example, shutdown at 11:15am, run the command below
sudo shutdown -r 11:15
To immediately shutdown the system without waiting, run the commands with the now option:
sudo shutdown now
That will start the shutdown immediately!
If you scheduled a shutdown and want to cancel, run the command with option -c
sudo shutdown -c "Canceling scheduled reboot"
That’s it! This is how one can reboot using system from the command line.
