Introduction

Now that you’ve planned your project, it’s time to start coding! This lesson will guide you through the steps of creating, testing, and finalizing your command-line tool.

Learning Objectives

  • Write and test your command-line tool.
  • Debug and refine your script.
  • Finalize and document your project.

Writing Your Script

Using your project plan, start coding your script. Focus on getting the basic functionality working first. Use the skills you’ve learned throughout this course, such as:

  • File management (cp, mv, rsync).
  • Process management (ps, kill).
  • Networking (ssh, scp).
  • Scripting constructs (variables, loops, conditionals).

Testing and Debugging

After writing your script, test it thoroughly:

  1. Test in different scenarios: Ensure your script works as expected in various conditions.
  2. Check for errors: Use echo to print variables and messages at different points in the script to help debug issues.
  3. Handle edge cases: Consider what might go wrong and how your script should handle such situations.

Finalizing Your Project

Once your script is working, finalize it by:

  1. Adding comments: Explain what each part of your script does to make it easier to understand.
  2. Documenting usage: Create a README.md file that explains how to use your tool.
  3. Testing again: Run final tests to ensure everything is working correctly.

Summary

In this lesson, you wrote, tested, and finalized your command-line tool. Congratulations on completing your final project! This project is a testament to the skills you’ve learned in this course.
