How to Execute a Ruby Script in Terminal? 💎💻

So, you've set up your Mac with all the necessary tools, written a fabulous Ruby script, and saved it as a .rb file. Now, you're eager to see the magic happen by executing it in the Terminal. I totally get it! In this guide, we'll go over the steps to execute your Ruby script seamlessly in Terminal. Let's dive in! 🚀

Step 1: Open Terminal 🖥️

To execute your Ruby script, you need to open the Terminal app on your Mac. You can find it by using Spotlight Search or by navigating to the "Applications" folder → "Utilities" folder → "Terminal" app. Got it? Great! Let's move on.

Step 2: Navigate to the script's directory 📂

First things first, you need to navigate to the directory where your Ruby script is saved. For example, let's say your .rb file is saved on your desktop. To navigate to the desktop directory, use the cd command followed by the path of your desktop directory. You can copy and paste the following command into your Terminal:

cd ~/Desktop

Step 3: Check your Ruby version 🔍

Before executing the Ruby script, it's always a good idea to double-check your Ruby version. This step ensures compatibility and avoids any potential issues. To check your Ruby version, enter the following command:

ruby --version

This will display the installed Ruby version on your system. If you see the desired version, awesome! If not, make sure you have Ruby installed correctly.

Step 4: Execute the Ruby script 🚀

Now, it's time for the magical moment! To execute your Ruby script, simply enter the following command in Terminal:

ruby your_script_name.rb

Make sure to replace your_script_name.rb with the actual name of your Ruby script. Press Enter, and voilà! Your Ruby script will be executed, and any output will be displayed directly in Terminal. That's it! 😎

Troubleshooting Tips ⚠️

Encountered some bumps along the way? Don't worry, we've got you covered! Here are some common issues and their easy solutions:

1. "Command not found" error: If you see this error, it means the ruby command is not recognized. Ensure that Ruby is installed correctly and try running the ruby --version command again.

2. "No such file or directory" error: If you receive this error, double-check the path to your Ruby script. Make sure you properly navigated to the script's directory using the cd command.

3. Script not executing as expected: If your script isn't behaving as expected, carefully review your code for syntax errors or logical flaws. Sometimes, a small typo can cause unexpected behavior.
