title: redirection bash: content from variable, not from file
body: <p>i am using mutt to create and send mails from a bash script.</p>
  
  <p>like this:</p>
  
  <blockquote>
    <p>$ mutt -s SUBJECT MAIL_TO_ADDRESS  &lt; BODY_CONTENT_FILE </p>
  </blockquote>
  
  <p>So i always have to write a file before calling mutt, is there a solution to pass information directly from script or shell variable ? </p>
