Is there a command to open the shutdown GUI?

Question

I know I can shutdown from commandline - without a password: What command is executed when shutdown from the graphical menu in 14.04? but I can't see how to open the shutdown GUI. Is this possible?

Answer 1

• Shutdown:

  /usr/lib/indicator-session/gtk-logout-helper --shutdown
  

• Reboot

  /usr/lib/indicator-session/gtk-logout-helper --restart
  

• Logout

  /usr/lib/indicator-session/gtk-logout-helper --logout

You can also use another dialog:

gnome-session-quit --power-off
