We have all come to terms with the age of computers and technology. There is no stopping it but at the same time, we can’t live without it either. We find ourselves using computers for almost everything. From checking our email to doing our taxes, we use our computers for everything. One of the reasons why we use our computers so much is because of the power they have and the fact they are fast. One of the best things about computers is that they can be customized to do what we want and also to do things our way. One of the best ways to do this is to change the startup messages and shutdown messages. The messages that appear when the computer starts up and when it shuts down. ~~
The Linux operating system is an open source software that is freely available and has a massive community of users and developers. Linux is an alternative to the proprietary such as Windows and Mac. Linux can be installed on a computer either as an operating system or as a virtual machine. Linux and other Unix-like operating systems are widely used in servers, mainframes and supercomputers. As a desktop operating system, Linux is one of the most popular operating systems. A GUI (Graphical user interface) is not needed to use and administer Linux systems. You can access the Linux shell using the keyboard for all system administration. The main method for shutdown the Linux system is by using the shutdown command.
The Linux terminal is a pretty powerful tool. You can do just about anything with it, including shutting down your computer, of course.
In this article we will see how to use the Linux terminal to shut down or reboot your system.
To shut down a Linux machine, you must use the shutdown command. The basic syntax is as follows.
shutdown [flags] [time] [message, if any]
- Flags : These are settings that can be specified when the computer is shut down. This can be a shutdown, a power-down (default) or a simple reboot of the system.
- Time: This argument specifies the downtime.
- Message: Sends a message to all users for disabling.
In many recent Linux distributions, the shutdown command is simply an alias of the systemctl command and is therefore only available on the system for compatibility reasons.
If the command is used without arguments, the system simply schedules a shutdown one minute after the command is entered.

How do I schedule a shutdown under Linux?
If you want to schedule your Linux machine to shut down, use the shutdown command followed by a time.
sudo shutdown 10:00
In the example above, the unit would shut down at 10:00.
sudo shutdown +10
If you use this method, the system schedules a shutdown ten minutes after the command is executed.
To shut down the system immediately, run the following command.
sudo close now

How do I cancel a scheduled stop?
To cancel an already programmed stop, use the -c flag.

You cannot specify a time argument when using the -c option, but it is possible to name a custom message.
sudo shutdown -c shutdown interrupted

Frequently Asked Questions
What is the command to shutdown Linux server?
The shutdown command is used to bring down a system and end all user sessions, when the system is running Linux or other Unix systems. It can be used with or without the -h option or the -r option, to either halt the system or reboot it. The shutdown command can be used to gracefully shut down a Linux server. By default, the command will give users 10 seconds to log out of their session before powering them off. Users can cancel the shutdown by typing “shutdown –c” (or “shutdown –cancel”). They can also type “shutdown –h” (or “shutdown –h now”) to power off the server immediately. To shutdown a Linux server, enter:
How do I shutdown from command prompt?
If you’re a Linux user, you are used to typing commands at a terminal to perform actions. The same is true for shutting down your computer. To shut down your computer via a command line, use the shutdown command, which is built into most modern Linux distributions (including Ubuntu). Simply run the command from a terminal window and your computer will shut down. A computer will not deliver information by itself. There are two ways to send a message to a computer. One is to use a mouse and type the message into the keyboard. The other one is to use the command prompt. The command prompt is a little window with a blinking cursor that waits for the user to type a command into it.
