Cron: Every minute
Runs the job once every minute, 60 times an hour.
* * * * *Every minute of every hour, every day.
Field breakdown
| Minute | Hour | Day of month | Month | Day of week |
|---|---|---|---|---|
| * | * | * | * | * |
The five fields are, in order: minute (0–59), hour (0–23), day of month (1–31), month (1–12), and day of week (0–6, Sunday = 0).
Common use case
Near-real-time work like processing a job queue, health checks, or polling for new messages.
Watch out for
A job that occasionally takes longer than 60 seconds will overlap with the next run. Add a lock (e.g. flock) so two copies never run at once.
