title: Golang: extract data with Regex
body: <p>I'm trying to extract whatever data inside <code>${}</code>.</p>
  
  <p>For example, the data extracted from this string should be <code>abc</code>.</p>
  
  <pre><code>git commit -m '${abc}'
  </code></pre>
  
  <p>Here is the actual code:</p>
  
  <pre><code>re := regexp.MustCompile("${*}")
  match := re.FindStringSubmatch(command)
  </code></pre>
  
  <p>But that doesn't work, any idea?</p>
