Shutting Down Through Command Line Interfaces

For power users and system administrators, shutting down a computer via the command line is a fundamental skill. This method is especially useful when working remotely or when the graphical user interface is unavailable.

Windows Command Line

Using the Command Prompt or PowerShell, the `shutdown` command can be employed to turn off the computer:

`shutdown /s /t 0` — Initiates an immediate shutdown.
`shutdown /r /t 0` — Restarts the computer immediately.
`shutdown /h` — Puts the computer into hibernation.

macOS Terminal

The `shutdown` command is available with options:

`sudo shutdown -h now` — Shuts down immediately.
`sudo shutdown -r now` — Restarts immediately.
`sudo halt` — Stops all processes and powers off.

Linux Terminal

The shutdown command varies slightly depending on the distribution but generally follows this format:

`sudo shutdown now` — Shuts down immediately.
`sudo shutdown -h now` — Halts the system and powers off.
`sudo poweroff` — Powers off the system directly.
`sudo reboot` — Reboots the system.

Operating System	Command	Description
Windows	shutdown /s /t 0	Shutdown immediately
Windows	shutdown /r /t 0	Restart immediately
macOS	sudo shutdown -h now	Shutdown immediately
macOS	sudo reboot	Restart the system
Linux	sudo shutdown -h now	Shutdown and power off
Linux	sudo reboot	Restart the system

Configuring Automatic Shutdown Settings

Automatic shutdown settings allow the computer to power off after a specified period of inactivity or at a scheduled time. This can be useful for energy saving, system maintenance, or security purposes.

On Windows, users can configure automatic shutdown using the Task Scheduler:

Open Task Scheduler and create a basic task.
Set the trigger to a specific time or event.
Choose the action to “Start a program” and enter `shutdown.exe` with arguments such as `/s /f /t 0` to force shutdown immediately.
Configure conditions and settings as needed.

macOS users can schedule shutdowns using the Energy Saver preferences or by leveraging the `pmset` command in Terminal:

Go to System Preferences > Energy Saver > Schedule.
Set the desired shutdown or startup times.
Alternatively, use `sudo pmset repeat shutdown MTWRFSU 23:00:00` to schedule a daily shutdown at 11 PM.
