killport is a command-line utility that simplifies the process of terminating active processes and containers that are listening on specified ports. With support for both single and multiple port operations, this tool enhances system management across various platforms including Linux, macOS, and Windows. Developed in Rust, killport seamlessly combines flexibility with exceptional performance in process management tasks.

Key Features

• Efficient Termination: Quickly kill processes or containers on specified ports, accommodating both single and multiple port requests.
• Flexible Modes of Operation: Choose to target processes, containers, or both, depending on specific needs.
• Safe Dry-Run Option: Preview actions with the dry-run feature, allowing for safe assessments before actual termination commands are executed.
• Customizable Verbosity: Adjust the verbosity of logs with options for detailed output or quiet operation for minimal display.
• Comprehensive Signal Support: Use a variety of termination signals to exercise precise control over how processes or containers are terminated.
• Cross-Platform Compatibility: Fully functional on Linux, macOS, and Windows, providing versatile management capabilities.

Usage Examples

The command structure for killport is straightforward:

killport [OPTIONS] <ports>...

Example Commands

• To kill a single process running on port 8080:

  killport 8080
  

• To terminate processes on multiple ports with a specific signal:
