No time for commands? Scheduling tasks with cron means programs can run but you don't have to stay up late.
I have encountered situations where I need to run a job every two, three, or four hours. That can be accomplished by dividing the hours by the desired interval, such as */3 for every three hours, or 6-18/3 to run every three hours between 6 a.m. and 6 p.m. Other intervals can be divided similarly; for example, the expression */15 in the minutes position means "run the job every 15 minutes."
*/5 08-18/2 * * * /usr/local/bin/mycronjob.sh
This cron job runs every five minutes during every hour between 8 a.m. and 5:58 p.m.
I know how to do it with a script but I'm curious only about DirectAdmin's approach. I guess the settings in my screenshot are correct for what I'd like to do.
It'd be nice if there was a "Next Run:" feature on the page.
