Как выключить debian 11 через консоль
To shut down a running Debian GNU/Linux system, you must not reboot with the reset switch on the front or back of your computer, or just turn off the computer. Debian GNU/Linux should be shut down in a controlled manner, otherwise files might get lost and/or disk damage might occur. If you run a desktop environment, there is usually an option to “ log out ” available from the application menu that allows you to shutdown (or reboot) the system.
Alternatively you can press the key combination Ctrl + Alt + Del . If the key combinations do not work, a last option is to log in as root and type the necessary commands. Use reboot to reboot the system. Use halt to halt the system without powering it off [18] . To power off the machine, use poweroff or shutdown -h now . The systemd init system provides additional commands that perform the same functions; for example systemctl reboot or systemctl poweroff .
[18] Under the SysV init system halt had the same effect as poweroff , but with systemd as init system (the default since jessie) their effects are different.
