重启树莓派的 Python 脚本 [英] Python script to restart a Raspberry Pi

问题描述

我想我想要的很简单.

Python 脚本在 23 小时 59 分钟后重新启动我的 Raspberry Pi.我尝试这样做的原因，而不是使用 cron 作业设置时间，是 Pi 没有用于时钟的板载电池，所以我不在乎时间是什么(如果连接到互联网，它将获取当前时间)，从脚本开始倒计时 23 小时 59 分钟.

Python script to restart my Raspberry Pi after 23 hours and 59 minutes. The reason I am trying to do this, instead of set times with a cron job, is the Pi has no onboard battery for a clock so I don't care what the time is (if connected to internet, it will source current time), just a count down of 23 hours and 59 minutes from the script starting.

这是我所知道的；

def restart():
SendEmail = SendEmail "SYSTEM RESTART", "ncam.py auto restart initiated"      msg['Subject'], body)
command = "/usr/bin/sudo /sbin/shutdown -r now"
process = subprocess.Popen(command.split(), stdout=subprocess.PIPE)
output = process.communicate()[0]

我还想给自己发一封电子邮件，上面设置的参数如上.

Also I want to send an email to myself with the set parameters as above.

推荐答案

你会想要一些这样的变体:

You are going to want some variant of this:

 import time
 import os
 currentTime = time.time()
 tomorrow = currentTime + 86340000
 while time.time() < tomorrow:
     do.yourCode()
    
 os.system("poweroff")

在你的函数中加入类似的东西，它会做你想做的.

Put something like that in your function and it will do what you want.
