工具介绍

Cron uses five fields to describe when a Linux command should run. This generator turns familiar recurring schedule choices into a ready-to-copy expression.

人们为何使用此工具

  • Useful when cron syntax is difficult to remember.
  • Creates standard five-field Linux crontab expressions.
  • Copy the result directly into a crontab file or deployment script.

如何使用

  1. Choose how often the job repeats.
  2. Select the time and calendar values shown for that schedule.
  3. Copy the generated expression and place it before your shell command.
