What you need:

| int argc; | |
| char *argv[]; | |
| { | |
| int i; | |
| argc--; | |
| for(i=1; i<=argc; i++) | |
| printf("%s%c", argv[i], i==argc? '\n': ' '); | |

The normal controller/view flow is to display a view template corresponding to the current controller action, but sometimes we want to change that. We use render in a controller when we want to respond within the current request, and redirect_to when we want to spawn a new request.
The render method is very overloaded in Rails. Most developers encounter it within the view template, using render :partial => 'form' or render @post.comments, but here we'll focus on usage within the controller.
Cheat Sheets are greate but they are not a substitute for learning the framework and reading the documentation as we most certainly have not covered every potential example here. Please refer to the Rails Command Line Docs for more information.
You can get all of this information on the command line.
rails generate with no generator name will output a list of all available generators and some information about global options.
rails generate GENERATOR --help will list the options that can be passed to the specified generator.

When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.
To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.
Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.
The set lines
set -euxo pipefail is short for:set -e
set -u
You're taking your first steps into Ruby
A good introduction to programming in general. Easy on newer programmers.
