Jobber

Jobber is a lightweight utility for Unix-like systems that can run arbitrary commands, or "jobs", according to a schedule. It is meant to be a replacement for the classic Unix utility cron. Job execution history: you can see what jobs have recently run, and whether they succeeded or failed. Sophisticated error handling: you can control whether and when a job is run again after it fails. For example, after an initial failure of a job, Jobber can schedule future runs using an exponential backoff algorithm. Sophisticated error reporting: you can control whether Jobber notifies you about each failed run, or only about jobs that have been disabled due to repeated failures.
