how do i edit the crontab in the plesk Control panel?

Cron is a Unix utility which allows tasks to be automatically run in the background at regular intervals. Such tasks are usually called cronjobs. Crontab (cron table) is a file which contains the schedule of the specific tasks to be run at certain intervals.

Here is how you can access the Crontab tool in your Plesk Control Panel:

1. Login to your Plesk Control Panel. Use the information provided to you when the server was setup.
2. Click on Domains from the navigation bar on the left.

3. Select the domain name you'd like to manage.
4. Click the Crontab icon in the Hosting section.

5. You will see a list of System users (includes FTP users and Web users setup on the server). Click the System user you'd like to setup a task for.
6. Click the Schedule a Task icon.

7. Now, you have to specify when to run your command.

• Minute - enter a value from 0 to 59.
• Hour - enter a value from 0 to 23.
• Day of the Month - enter a value from 1 to 31.
• Month - enter a value from 1 to 12, or select the month from the drop-down box.
• Day of the Week - enter the value from 0 to 6 (0 for Sunday), or select the day of the week from the drop-down box.

  You can schedule the time using the UNIX crontab entry format. In this format, you can:

• enter several values separated by commas. Two numbers separated by a hyphen mean an inclusive range. For example, to run a task on the 4th, 5th, 6th, and 20th of a month, type 4-6,20.
• insert an asterisk to specify all values allowed for this field. For example, to run a task daily, type * in the Day of the Month text box.

  To schedule the task to run every Nth period, enter the combination */N, where N is the legal value for this field (minute, hour, day, month). For example, */15 in the Minute field schedules the task to start every 15 minutes.

8. Type your command in the Command text field.
9. Click the OK button.
10. Now, click the Preferences icon.

11. Enter an email address where you want to receive crontab messages.
12. Finally, click OK.
