  1. Best Answer

    For shutdown:

    sudo poweroff

    For restart:

    sudo reboot

    Appendix: If your keyboard is "locked up", so you can't enter a command like "reboot" which would run from "su" anyway, use the keyboard: hold down Alt + PrintScreen/SysRq, buttons and type "REISUB". It doesn't have to be capital letters. It will restart your computer gently. http://blog.kember.net/articles/reisub-the-gentle-linux-restart/

  2. Open your terminal with CTRL+ALT+T and do these following commands

    To shutdown the system:

    sudo shutdown -h now

    To restart:

    sudo reboot

    & one more command for restart:

    sudo shutdown -r now

    Another way as one of the user mentioned.

    For shutdown:

    sudo halt

    or:

    sudo init 0

    For restart:

    sudo init 6

    You can get more info on the shutdown command by using one of the following:

    • shutdown --help
    • man shutdown

  3. Hate passwords (sudo) and love one-liners?

    For Ubuntu 15.04 and later

    This is due to Ubuntu's shift in using systemd instead of Upstart

    systemctl poweroff
systemctl reboot
systemctl suspend
systemctl hibernate
systemctl hybrid-sleep

    Since hibernate is normally disabled by default in Ubuntu systems, you can enable this by checking this answer.

    For Ubuntu 14.10 or earlier

    Shutdown:

    /usr/bin/dbus-send --system --print-reply --dest="org.freedesktop.ConsoleKit" /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Stop

    Restart:

    /usr/bin/dbus-send --system --print-reply --dest="org.freedesktop.ConsoleKit" /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Restart

    Other commands you may like:

    Suspend:

    /usr/bin/dbus-send --system --print-reply --dest="org.freedesktop.UPower" /org/freedesktop/UPower org.freedesktop.UPower.Suspend

    Hibernate: (if enabled on your system)

    /usr/bin/dbus-send --system --print-reply --dest="org.freedesktop.UPower" /org/freedesktop/UPower org.freedesktop.UPower.Hibernate

  4. On 16.04 no need of sudo

    To shutdown/poweroff:

    poweroff

    To reboot:

    reboot

  5. Use

    sudo shutdown -h (time) (message)

    This will shutdown your computer and halt it. That is what the -h is for. Then, in the time area you can choose the shutdown delay (in minutes) and if you want you can send a broadcast message in the message area (like goodbye, or I'm shutting the thing down :P).

    To restart the computer, type

    sudo shutdown -r (time) (message)

    Now, instead of shutting it down and halting it, you will restart your computer once it's shutdown. :)
