How to Execute Ruby Files and Commands in Console

1. Execute a Ruby Program in the Console
2. Install Ruby in Your System

You may be found some online interpreters to code, compile and run Ruby codes online, but if you are willing to have Ruby in your system terminal, you need to install it first.

In this article, we will discuss how we run a Ruby program in the system console and install Ruby in our system if necessary.

We will see an example relevant to the topic to make the topic easier. Also, we are going to see the installation process of Ruby in local systems so that you can take a look at it if Ruby is not present in your system.

Execute a Ruby Program in the Console

To execute a Ruby program in your console, follow the example below. In our below example, we are going to run a Ruby file named example.rb, and the command will look like this:

ruby example.rb

And it will show you the output of the example.rb file.

Interactive Ruby Environment

If you want to code directly in the console, then you can start the Interactive Ruby Environment by the following command:

irb

Now you can run the Ruby command directly in your console like the below:

irb(main):001:0> puts "DelftStack"
DelftStack
=> nil
irb(main):002:0>

Install Ruby in Your System

You cannot run the Ruby commands or files in your system if your system doesn’t contain Ruby. To install Ruby in your system environment, follow the below steps.
