title: How to split a string into an array in Bash?
body: <p>In a Bash script, I would like to split a line into pieces and store them in an array.</p>
  <p>For example, given the line:</p>
  <pre><code>Paris, France, Europe
  </code></pre>
  <p>I would like to have the resulting array to look like so:</p>
  <pre><code>array[0] = Paris
  array[1] = France
  array[2] = Europe
  </code></pre>
  <p>A simple implementation is preferable; speed does not matter. How can I do it?</p>
