Ideally you may not have a requirement to schedule a job every minute. But understanding this example will will help you understand the other examples mentioned below in this article.

* * * * * CMD

The * means all the possible unit — i.e every minute of every hour through out the year. More than using this * directly, you will find it very useful in the following cases.

  • When you specify */5 in minute field means every 5 minutes.
  • When you specify 0-10/2 in minute field mean every 2 minutes in the first 10 minute.
  • Thus the above convention can be used for all the other 4 fields.
