📝 Notes

• Tools prefixed with ls* follow a consistent pattern for listing system information
• Python versions (when available) offer enhanced features over shell versions
• Most tools include --debug and --help options for detailed information
• Many tools require root privileges for full functionality

🏗️ Architecture

This toolset includes both original shell scripts and enhanced Python rewrites:

• Enhanced Python versions: Improved error handling, debug output, and additional features
• Original shell versions: Preserved for compatibility and reference
• Consistent interface: Similar command-line options across related tools
