Command for shutdown

Support
1

The shutdown menu in KDE plasma 6 (when clicking on shutdown in the task manager) is really neat. It opens a GUI with options to shutdown, sleep, log out, restart or cancel, and start a 30 second cooldown before shuting down. In the meantime, it doesn’t close anything. I love it.

What is the command for it though? I would love to make a keyboard shortcut for it (instead of the command poweroff which can be risky)

The commands used by the gui is the systemctl commands

 $ file /usr/bin/poweroff
/usr/bin/poweroff: symbolic link to systemctl

poweroff is just the short version and not risky at all

systemctl poweroff

 $ systemctl --help

Try any of these:

qdbus org.kde.LogoutPrompt /LogoutPrompt promptLogout

qdbus org.kde.LogoutPrompt /LogoutPrompt promptReboot

qdbus org.kde.LogoutPrompt /LogoutPrompt promptShutDown

You can also skip this Log out Screen… so when you click on this buttons it can do all this options without any delay.

I like the gui and wonder if there is a command to open the gui.

I had set a shortcut to poweroff which worked well but I find it risky - if I enter it by mistake I can lose what I am currently working on. So I removed it.

Ahh - that ‘risky’ - I thought it had something to do with the system.

Then you are correct - the wayland shell command is the way to go - I simply misunderstood you initial topic.
