cronic

cronic is a command line tool designed to help manage and troubleshoot the output of command-line programs running in cron jobs. Cron is a time-based job scheduling program found in Unix-like operating systems.

The purpose of cronic is to capture the output of a command run by cron and send it via email only if the command produces any output on stderr. This is useful for automated tasks that run in cron jobs, as it allows administrators to receive email notifications only when there is an error or unexpected output.

When a command is executed with cronic, it captures any output on stderr and only sends an email if there is non-empty stderr output. If the command produces no output or only output on stdout, no email is sent. This helps to reduce unnecessary emails and ensures that administrators are alerted only in case of errors.

Cronic also prefixes the output of the command with a timestamp, making it easier to track when the command was executed and troubleshoot any potential issues.

Overall, cronic is a handy tool for managing cron job outputs, as it helps streamline notifications and ensures that administrators are informed only when necessary.
