title: Where do I put my ruby program on mac when opening with terminal
body: <p>I'm following this guide:</p>
  
  <p><a href="http://www.math.umd.edu/~dcarrera/ruby/0.3/chp_01/programs.html" rel="nofollow noreferrer">http://www.math.umd.edu/~dcarrera/ruby/0.3/chp_01/programs.html</a></p>
  
  <p>and I'm trying to create my first ruby program. So I wrote it in a text editor, but now I dont know how to open through terminal. Rather, where should I be saving the program to (directory).</p>
  
  <p>Thanks!</p>
  
  <p>(I'm new to programming on mac) :(</p>
