Crontab Entries

Not sure what to enter?

Add one line per scheduled job - timing, command and an optional comment - and copy the finished crontab.

What is a crontab?

A crontab is the list of scheduled commands for one user on a Linux server. Each line has a schedule (five time fields) and the command to run, and lines starting with # are comments. This generator lets you add jobs one by one and gives you the finished crontab to paste in.

How to generate a crontab

Enter the schedule for the first job (for example 0 3 * * * for 3 AM daily).
Enter the full command, with absolute paths, and an optional comment.
Add more entries if you need them, then click Generate.
Run crontab -e on the server and paste the result.

Related checks

To understand or double-check a schedule, use the Cron Expression Builder.
To make sure your site stays up after server changes, use the Website Status Checker.

Keep the comments: in six months they are the only record of why each job exists. If a job maintains your website (backups, cache warm-up, renewals), add the site to JustChecker monitoring so a broken job shows up as an alert instead of a surprise.
