title: Add content of the file as body in mail unix
body: <p>I want to add contents of file in body part of the mail in unix,
  Also before the file I want to add some text.</p>
  <p>Now I'm using this</p>
  <pre><code>echo &quot;Text is here&quot; &gt;&gt; Filename
  mailx -s &quot;subject&quot; zzz@z.com  &lt; Filename.
  </code></pre>
  <p>It edited the file.
  So,I want my mail body to be like this.</p>
  <blockquote>
  <p>Text is here</p>
  <p>Content of file.</p>
  </blockquote>
  <p>I want to do this without editing the file.</p>
