How to execute a Ruby script in Terminal?

 

I've set everything up that I need on my Mac (Ruby, Rails, Homebrew, Git, etc), and I've even written a small program. Now, how do I execute it in Terminal? I wrote the program in Redcar and saved it as a .rb, but I don't know how to execute it through Terminal. I want to run the program and see if it actually works. How do I do this?

Just call: ruby your_program.rb

or

  • start your program with #!/usr/bin/env ruby ,
  • make your file executable by running chmod +x your_program.rb
  • and do ./your_program.rb some_param

    • 假设红宝石解释器在你的PATH中（它应该是），你只需运行

    ruby your_file.rb

    Open your terminal and open folder where file is saved.
    Ex /home/User1/program/test.rb

  • Open terminal
  • cd /home/User1/program
  • type: ruby test.rb

    • format or test.rb 

    class Test 
  def initialize
   puts "I love India"
  end
end

# initialize object
Test.new

    output 

    I love India
