将 cron 选项卡设置为工作日的特定时间

我试图在 Ubuntu 服务器上安装 cron 作业。我们希望 cron 作业在一天中的特定时间和一周中的特定日子运行脚本。例如，我们希望设置一个 cron 作业，它按照以下顺序运行脚本:

在工作日，从上午9点到下午2点，每2分钟执行一次脚本。

这就是我目前所能做到的:

*/209-14 * * */path _ to _ script

平日我应该做什么？

最佳答案

Same as you did for hours:

*/2 09-18 * * 1-5 /path_to_script

0 and 7 stand for Sunday
6 stands for Saturday
so, 1-5 means from Monday to Friday

You state 2pm in your requirement, hour range should end at 14 instead of 18 (which is 6pm).

*/2 9-14 * * 1-5 /path_to_script

man crontab

In fact the last hour you want the script to run is 13:00 to 13:59, so you want:

*/2 9-13 * * 1-5 /path_to_script

meaning the first runtime will be 9:00, then 9:02, and so on until 13:58 which will be the last run as 14:00 is not included.
