GNOME 的关机命令

我使用 GNOME Shell 右上角的图标来关闭我的系统。

哪个命令用于关闭系统？

  • shutdown -h now
  • 完全不同的东西？

关机的命令是：

dbus-send --system --print-reply --dest=org.freedesktop.login1 /org/freedesktop/login1 "org.freedesktop.login1.Manager.PowerOff" boolean:true

为了理解

man systemd-logind

systemd-logind is a system service that manages user logins. It is
       responsible for:

       ·   Keeping track of users and sessions, their processes and their idle
           state

       ·   Providing PolicyKit-based access for users to operations such as
           system shutdown or sleep

       ·   Implementing a shutdown/sleep inhibition logic for applications

       ·   Handling of power/sleep hardware keys

       ·   Multi-seat management

       ·   Session switch management

       ·   Device access management for users

       ·   Automatic spawning of text logins (gettys) on virtual console
           activation and user runtime directory management
