how to run a ruby file in terminal

To run a Ruby file in the terminal, follow these steps:

1. Open your terminal application. You can find it in the Applications folder on macOS or by searching for "Terminal" in the Start menu on Windows.

2. Navigate to the directory where your Ruby file is located. Use the cd command followed by the directory path. For example, if your file is located in the "Documents" folder, you can use the following command: cd Documents

3. Once you are in the correct directory, you can run the Ruby file using the ruby command followed by the file name. For example, if your file is named "example.rb", you can use the following command: ruby example.rb

4. Press Enter to execute the command. The Ruby file will be executed, and any output or errors will be displayed in the terminal.

That's it! You have successfully run a Ruby file in the terminal.

Please note that you need to have Ruby installed on your computer for this to work. If you don't have Ruby installed, you can download it from the official Ruby website: https://www.ruby-lang.org/
