如何从 0 分钟以外的时间开始每 5 分钟运行一次 cron 作业? [英] How can I run a cron job every 5 minutes starting from a time other than 0 minutes?

问题描述

我想每 5 分钟运行一个脚本，假设从 13:02 开始，这样我可以每 5 分钟运行另一个脚本，但从 13:04 开始，所以第二个脚本在第一个脚本开始后两分钟运行工作.我怎样才能做到这一点?

I would like to have a script run every 5 minutes let's say starting from 13:02 so I can have another script runs every 5 minutes but starting from 13:04 so the second script runs two minutes after the start of the first job. How can I achieve this?

推荐答案

语法 1

*/5+2 * * * * 1st-script
*/5+4 * * * * 2nd-script

为了将来参考，请查看此在线Cron Job Generator.

由于有多个报告称 + 语法在 Ubuntu 14.04 上不起作用，这里有一个变体:

Since there are several reports that the + syntax is not working on Ubuntu 14.04, here's a variation:

2-59/5 * * * * 1st-script
4-59/5 * * * * 2nd-script

这将导致第一个脚本每 5 分钟运行一次，在每小时开始时的偏移量为 2 分钟，而第二个脚本的行为相同，偏移量为 4 分钟.

This will result in the 1st script to run every 5 minutes starting with an offset of 2 minutes at the beginning of each hour and the 2nd script to behave the same with an offset of 4 minutes.
