bcron is a cron scheduling system designed with an emphasis on secure operation. It executes commands according to recurring schedules while maintaining a familiar interface for users accustomed to traditional Unix cron implementations.
The principal difference between bcron and conventional cron systems is its internal architecture. Rather than concentrating scheduling, configuration management, and execution responsibilities within one large daemon, bcron separates these functions into several cooperating programs.
Each component performs a specific task, and communication between components is deliberately controlled. This arrangement is intended to reduce the privileges required by individual processes and provide clearer separation between operations performed on behalf of users and those requiring elevated permissions.
The system retains compatibility with conventional crontab workflows, making it possible to use familiar scheduling configurations while benefiting from its alternative internal design.
This is free and open source software.
Key Features
- Execute scheduled commands using familiar cron-style configuration files.
- Separate scheduling, command execution, and configuration management into distinct components.
- Use controlled communication channels between cooperating processes.
- Provide bcron-sched for handling scheduled execution.
- Use bcron-exec to manage the execution of scheduled jobs.
- Provide bcron-spool for receiving and managing user crontab submissions.
- Use bcron-update to monitor and incorporate changes to system crontab configurations.
- Maintain user crontab files in a protected spool directory.
- Support integration with process supervision systems.
- Allow configuration through environment variables and configuration directories.
- Provide a familiar interface for administrators migrating from Vixie cron-style systems.
