MYTTL

MYTTL, which stands for "My Time To Live," is a lightweight and open-source tool designed to manage and enforce time-based access control for files and directories in Unix-like operating systems. It operates by dynamically adjusting file permissions based on predefined expiration rules, ensuring sensitive or temporary data is automatically restricted after a specified duration.

Developed as a command-line utility, MYTTL allows users to set expiration times for files and directories, after which access permissions are revoked. This functionality is particularly useful in environments where temporary access to files is required, such as shared workspaces, collaborative projects, or secure data handling scenarios. The tool integrates with standard Unix file permissions, making it a seamless addition to existing workflows without requiring significant infrastructure changes.

MYTTL is written in Python and relies on the system’s underlying file permission mechanisms. It supports both individual files and entire directory trees, enabling granular control over access expiration. The tool can be configured via command-line arguments or configuration files, allowing administrators to define expiration policies for different use cases. For example, a directory containing draft documents might be set to expire after 7 days, while a temporary log file could be configured to self-destruct after 24 hours.

The project emphasizes simplicity and security, avoiding complex dependencies while ensuring reliability. MYTTL is distributed under an open-source license, permitting free use, modification, and distribution. It is maintained by a small community of developers focused on improving file security and automation in Unix environments.

While MYTTL is not widely adopted outside niche use cases, it serves as a practical solution for users seeking automated permission management. Its ease of use and compatibility with existing systems make it a valuable tool for developers, system administrators, and security-conscious individuals managing temporary or sensitive data.
