Frequently Asked Questions
A cron job is a scheduled task that runs automatically at specified times on Unix-like systems. The name comes from "chronos" (Greek for time). Cron is used for backups, log rotation, report generation, cache clearing, and any repetitive task.
*/n means "every n units". So */5 in the minute field means every 5 minutes (0, 5, 10, 15…). */2 in the hour field means every 2 hours (0, 2, 4, 6…).Both 0 and 7 represent Sunday in cron. Monday is 1, Tuesday 2, … Saturday 6. Some systems only accept 0–6, others accept 0–7. Using 0 is the safest for maximum compatibility.
