    The format contains five separate spaces to create timeslots, followed by the actual command.

    The saved schedule is in a nice “crontab” file that lists tasks with additional guidelines. You can modify certain files via SSH with the crontab command type, but cPanel & Is whm is faster and easier, including two user interfaces for task scheduling, one with serving cPanel scripts and one for the scripts we use to run we will take on see for yourself in the next section.

    Before our company has access to the cPanel cron interface, you need to understand the notation of intervals.

  • Minutes is a large number from 0 to 59.
  • Hours are a fabulous number from 0 to twenty-three. Cron uses the 24-hour format, so 16:00 is 16:16. 23 etc
  • The days associated with the month are the number connecting 1 and 31.
  • Month – choose between 1 and 12.
  • Days of the new week A – a number from 6 to 7, where Sunday is represented by the number 0 or 7.

Since the Month and Day of the Week fields contain asterisks, the script is set to days and months, since the rest of the fields are generally valid; all this every time, day and month.

    Let’s look at more complex reviews. You have a browsing script that you want to run almost every hour, every hour, from 90 am to 5 pm, but always on weekdays. To do this, we need to enter another note from the scale.
