title: Setting path for rails 3.2.8 in Ubuntu 12.10
body: <p>I am completely new to Ubuntu, I am trying to complete my installation of Ruby On Rails, so far I have installed both Ruby 1.9.3 and set it as the default and I installed Rails 3.2.8, when I open a new terminal it doesn't recognise my Rails install and I understand from looking for help that I need to set a path in a bashrc file. </p>
  
  <p>2 problems I have is trying to understand what my path is and how I input this to the bashrc file(how can I find the file or do I use a command in the terminal to do set the path)</p>
  
  <p>Here is the location of my Ruby and Rails install</p>
  
  <pre><code>andrew@andrew-laptop:~$ sudo updatedb
  [sudo] password for andrew: 
  andrew@andrew-laptop:~$ locate rails|grep -e "bin/rails$"
  /home/andrew/.rvm/gems/ruby-1.9.3-p286/bin/rails
  /home/andrew/.rvm/gems/ruby-1.9.3-p286/gems/railties-3.2.8/bin/rails
  </code></pre>
  
  <p>I tried this but nothing changed</p>
  
  <pre><code>andrew@andrew-laptop:~$ export PATH=$PATH:/home/andrew/.rvm/gems/ruby-1.9.3-p286/bin
  </code></pre>
