How to Shutdown Ubuntu Server [Beginner's Tip]

To shutdown Ubuntu server immediately, you can use the shutdown command like this:

sudo shutdown now

Yes. You need to be a sudo user or root to shut down a Linux server because it is an administrative task.

Some people prefer to use shutdown -h now but that's not required as both refer to power-off.

Keep in mind that you must have a way to power it on back again otherwise prefer to reboot remote Ubuntu servers.

How to shutdown Ubuntu server

Linux shutdown command is not the only way to shut down Ubuntu or other Linux from the terminal. There are other commands that can be used to shutdown Linux from the shell.

But first let's take another look at it this command.

1. Poweroff Ubuntu using shutdown command

You can use the shutdown command without any options. This will schedule a shutdown a minute from your current time.

sudo shutdown

You can cancel the scheduled shutdown with option -c:

sudo shutdown -c

No message is displayed when the shutdown is cancelled.

Here's a screenshot of what it looks using the above commands. I have used Debian server in the image below but it should be the same for Ubuntu as well.

2. Shutdown Ubuntu using systemd

You can use systemd command to shutdown i.e. power off an Ubuntu server or desktop.

sudo systemctl poweroff

3. Immediately shutdown Ubuntu server using poweroff

Can't wait for the shut down? You always have the shutdown now for that. Another way to shut down immediately is by using the poweroff command:

sudo poweroff
