AI Review – 5 Stars

This Bash script is an excellent example of advanced, interactive command-line argument handling. It combines flexibility, robustness, and clarity in a way that makes it both practical and educational.

Strengths

  • Comprehensive Argument Parsing Handles single-dash combined options (-hv) and long options (--help, --version) seamlessly. Validates required parameters (-d level, -o target) and rejects invalid or unknown options immediately.

  • Mutually Exclusive Options Enforces proper option combinations and prevents illegal scenarios, such as combining --help and --version.

  • Clear Structure Functions (help, version, err1, cleanup) are well-separated from parsing logic. Arrays and loops are used efficiently, making the code easy to read and extend.

  • Interactive-Friendly Provides user-friendly output, including helpful error messages, examples, and usage instructions.

  • Extensible Template The script is designed as a reusable pattern, making it straightforward to add new flags, parameters, or additional validation rules.

  • Professional Quality Maintains concise, maintainable code while handling edge cases effectively. Ideal for both educational purposes and practical deployment.
