如何在每次启动时运行Python脚本？

Question

我有以下脚本：

#! /usr/bin/python

import glib
import re
import subprocess
import requests
import bs4
import datetime
import sys
import os
import time
from selenium import webdriver
from pyudev import Context, Monitor
from selenium.common.exceptions import NoSuchElementException

def demote():
    def result():
        os.setgid(100)
        os.setuid(1000)
    return result

def inotify(title, message):
    subprocess.call(['notify-send', '{}\n'.format(title), '{0}\n'.format(message)], preexec_fn=demote())
    #os.system('notify-send ' + title + ' ' + message)

def get_network_data(tout):
    """Scrapes balance data from ISP website."""

    if tout is not None:
        try:
        # Do some scraping
            if data_found:
                full_msg = '{0}\n{1}'.format(my_balance.capitalize(), airtime_balance.capitalize())
                inotify('My Balance', full_msg)
                #subprocess.call(['notify-send', 'My Balance', '\n{0}\n{1}'.format(my_balance.capitalize(), airtime_balance.capitalize())], preexec_fn=demote())

            else:
                print('Could not retrieve data from page...')
                full_msg = '{0}'.format('Error: Could not retrieve data from page.')
                inotify('My Balance', full_msg)
                #subprocess.call(['notify-send', 'My Balance', '\n{0}'.format('Error: Could not retrieve data from page.')], preexec_fn=demote())

        except NoSuchElementException:
            print('Could not locate element...')
            full_msg = '{0}'.format('Error: Could not locate element - acc.')
            inotify('My Balance', full_msg)
            #subprocess.call(['notify-send', 'iMonitor:get_network_data', '\n{0}'.format('Error: Could not locate element - acc.')], preexec_fn=demote())

    else:
        print('Could not find USB device...')
        full_msg = '\n{0}'.format('Error: Could not find USB device.')
        inotify('My Balance', full_msg)
        #subprocess.call(['notify-send', 'iMonitor', '\n{0}'.format('Error: Could not find USB device.')], preexec_fn=demote())

def identify_phone(observer, device):
    """Identifies if specific USB device (phone) is connected (tethered)."""

    global last_updated, initial_search, msg_count

    current_time = datetime.datetime.now()
    time_diff = current_time - last_updated

    if (time_diff.seconds > 300) or initial_search:
        try:
            time.sleep(0.25)
            tout = subprocess.check_output("lsusb | grep 1234:5678", shell=True)
        except subprocess.CalledProcessError:
            tout = None

        last_updated = datetime.datetime.now()
        initial_search = False

        get_network_data(tout)

    if time_diff.seconds > 10:
        msg_count = 1

    if not initial_search and msg_count == 1:
        wait_time = datetime.datetime.fromtimestamp(600 - time_diff.seconds)
        message = wait_time.strftime('You may have to wait %-M minute(s), %-S second(s) before another check is done.')
        print('Could not retrieve data from page...')
        full_msg = '\n{0}'.format(message)
        inotify('My Balance', full_msg)
        #subprocess.call(['notify-send', 'iMonitor:Identify Phone', '\n{0}'.format(message)], preexec_fn=demote())
        msg_count += 1

try:
    initial_search = True
    last_updated = datetime.datetime.now()
    msg_count = 1
    try:
        from pyudev.glib import MonitorObserver

    except ImportError:
        from pyudev.glib import GUDevMonitorObserver as MonitorObserver

    context = Context()
    monitor = Monitor.from_netlink(context)

    monitor.filter_by(subsystem='usb')
    observer = MonitorObserver(monitor)

    observer.connect('device-added', identify_phone)
    monitor.start()

    glib.MainLoop().run()

except KeyboardInterrupt:
    print('\nShutdown requested.\nExiting gracefully...')
    sys.exit(0)

我希望它在整个启动过程中运行，因此，我创建了一个服务来/etc/systemd/system调用脚本。然而，由于该脚本旨在显示桌面通知，因此我还没有设法使其工作，因为它以 root 身份运行；尽管我已经更改了 guid 和 uid，但还是如此。任何帮助，将不胜感激。

在我们的主目录下创建.xinitrc文件（如果不存在）。然后添加这个：

bash <absolute/path/to/your/script.py> &

这将使您的脚本在您的 X 服务器启动时启动（当您的桌面环境启动时）。
