Question

我对linux比较新，所以希望这很简单，虽然我无法通过搜索找到答案。我正在使用cron（Debian Jessie在Raspberry pi上）每天凌晨1点运行一个脚本，它会在不到一天的时间内休眠一段时间，然后运行另一个脚本。它工作正常，但我也尝试实现一个日志，以便我可以看到脚本运行的时间列表，并注意它是否没有按时启动。当我手动运行脚本时，日志写得很好，但是当我通过cron触发它时，不会创建任何日志。有人有建议吗？代码如下：

#!/usr/bin/python

from random import randint
import os
from time import sleep
import logging
import datetime

now = datetime.datetime.now()

time = now.hour*3600 + now.minute*60 + now.second # current time in seconds

logging.basicConfig(filename='script.log',level=logging.DEBUG)

sleep_time = randint(0,70000)

total_sec = sleep_time + time
hours = total_sec/3600
minutes = (total_sec%3600)/60
seconds = total_sec%60
if minutes < 10:
    minutes = "0" + str(minutes)
if seconds < 10:
    seconds = "0" + str(seconds)


logging.info(" Job started at " + str(now) + ". Will sleep for " + str(sleep_time) + " seconds. Script will begin at " + str(hours) + ":" + str(minutes) + ":" + str(seconds) + ".")

if time < 3500 or time > 3700:
    logging.warning(" Script did not start at specified time. Script began at " + str(now))

sleep(sleep_time)
os.system("/path/to/program.py")

Python日志模块在cron中运行时不写
