In lines like:
require "./hello.rb"
What does the single period do? I know that using 2 periods is going back a directory from current location.
Also, is there a difference in the following:
require_relative "../file.rb"
require "../file.rb"

2. Is the current directory, basically it's the same as `hello.rb` – Sami Kuhmonen Jun 27 '15 at 21:02

Cool, thank you. Another question: Is `require "./hello.rb"` the same as using `require_relative "hello.rb"` ? – philip yoo Jun 27 '15 at 21:03

In Unixy systems, the dot refers to the current working directory. The two dots in your second and third examples, refer to the parent of your working directory.
As for require_relavive vs require see this question: What is the difference between require_relative and require in Ruby?
Short answer: If your ruby script lives in /scripts/bin/, and you run it from /home/work :
require "./file.rb"pulls in/home/work/file.rbrequire_relative "./file.rb"pulls in/scripts/bin/file.rb
