Linux关闭与dbus发送 [英] Linux Shutdown with dbus-send

问题描述

我正在编写一个Java应用程序来远程关闭我的Linux文件夹。

I am writing a Java app to shutdown my Linux box remotely.

桌面应用程序就位，并等待发送命令。我已经尝试使用shutdown -h，但这需要sudo权限，不是一个选项。然后我找到了一种方法，使用下面的dbus-send解决方案关闭没有sudo：

The desktop app sits and waits for a command to be sent to it. I have tried using "shutdown -h" but this requires sudo privileges and is not an option. I then found a way to shutdown without sudo using the following dbus-send solution:

dbus-send --print-reply --system --dest=org.freedesktop.Hal /org/freedesktop/Hal/devices/computer org.freedesktop.Hal.Device.SystemPowerManagement.Shutdown

这工作正常，但我想弄清楚，使用dbus-send，如果它可能做一个定时关机类似于关闭3600，这将关闭电脑在1小时？

This works fine but I am trying to figure out, using dbus-send, if its possible to do a timed shutdown similar to "shutdown 3600" which would shut the computer down in 1 hour?

干杯

推荐答案

HAL，您正在呼叫的功能，不提供此功能。但是你可以随时用这样的东西，如果你正在启动一个外部命令：

HAL, which function you are calling, does not provide this feature. But you can always go with something like this, if you are launching an external command anyway:

sh -c "sleep 1h; dbus-send --print-reply --system --dest=org.freedesktop.Hal /org/freedesktop/Hal/devices/computer org.freedesktop.Hal.Device.SystemPowerManagement.Shutdown"
