Installation

Using Bundler (recommended)

Add RubyShell to your Gemfile:

gem 'rubyshell'

Then run:

bundle install

Or add it directly with:

bundle add rubyshell

gem install rubyshell

require 'rubyshell'

This extends Kernel with the sh method, making it available everywhere in your Ruby code.

require 'rubyshell'

sh do
  puts pwd
end

If you see your current directory printed, RubyShell is working correctly.
