How can I shut down or reboot Ubuntu using terminal commands?
Appendix: If your keyword is "lockup" 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/
Open your terminal with CTRL+ALT+T and do these following commands
To shutdown the system:
sudo shutdown -h now
& one more command for restart:
sudo shutdown -r now
Another way as one of the user mentioned.
sudo init 0
sudo init 6
You can get more info on the
shutdown command by using one of the following:
Hate passwords (sudo) and love one-liners?
For Ubuntu 14.10 or earlier:
/usr/bin/dbus-send --system --print-reply --dest="org.freedesktop.ConsoleKit" /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Stop
/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:
/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
For Ubuntu 15.04 and later:
(This is due to Ubuntu's shift in using
systemd instead of
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: https://askubuntu.com/a/617254/101985
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 brodcast 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 shuting it down and halting it, you will restart your computer once it's shutdown. :) Best of luck
