我使用crontab运行三个独立的python脚本，每个脚本的输出都通过管道输出到一个日志文件，这三个python脚本中只有一个运行时带有输出。
这是crontab文件：
# Edit this file to introduce tasks to be run by cron.
#
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
# and what command to run for the task
#
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use '*' in these fields (for 'any').
#
# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.
#
# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
#
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
#
# For more information see the manual pages of crontab(5) and cron(8)
#
# m h dom mon dow command
@reboot sleep 60 && sh /home/pi/GLaDOS/launcherCheck.sh >/home/pi/logs/check.log 2>&1

crontab文件打开三个不同的.sh文件(如下所示(，它们都配置有"chmod 755[name].sh"。

我没有收到错误消息，程序似乎没有运行——我知道这一点是因为我查看了每个日志文件的输出(https://i.stack.imgur.com/znqJh.png)，正如您所看到的，这两个脚本都有效，但emailCheck没有。
这些程序不在crontab中时都能工作。
还有一点值得注意的是，在重新格式化sd卡后，程序似乎可以工作(尽管这是通过rc.local实现的(，所以我开始怀疑sd卡有某种退化——但因为我对树莓pi知之甚少，我认为这可能是最好的地方。
欢迎所有和任何解决方案，
马修。
已解决！
程序正在运行，判断它是否正在运行的唯一方法是打印到shell——我没有查看shell。解决方案是使用(import-logger(将日志写入一个文件，这意味着我可以检查一个文件来查看脚本是否正在运行。
