我正在试图弄清楚如何在每个星期天运行crontab作业。我认为以下应该可以工作，但我不确定我是否理解正确。以下内容正确吗?
5 8 * * 6

下面是对crontab格式的解释。
# 1. Entry: Minute when the process will be started [0-60]
# 2. Entry: Hour when the process will be started [0-23]
# 3. Entry: Day of the month when the process will be started [1-28/29/30/31]
# 4. Entry: Month of the year when the process will be started [1-12]
# 5. Entry: Weekday when the process will be started [0-6] [0 is Sunday]
#
# all x min = */x
所以根据这个，你的5 8 * * 0会在每周日8:05运行。
crontab网站提供了实时结果显示:https://crontab.guru/#5_8_*_*_0
以人类可读的方式使用crontab构建器的Cron作业表达式
* * * * 0
you can use above cron job to run on every week on sunday, but in addition on what time you want to run this job for that you can follow below concept :
* * * * * Command_to_execute

@每周工作对我更好! 例如，添加crontab -e，它将在每个周日0:00 AM工作 @weekly /root/fd/databasebackup/week.sh >> ~/test.txt
