title: mutt command with multiple attachments in single mail unix
body: <p>My requirement is to attach all the .csv files in a folder and send them in a single mail.</p>
  
  <p>Here is what have tried,</p>
  
  <pre><code>mutt -s "subject" -a *.csv -- abc@gmail.com &lt; subject.txt
  </code></pre>
  
  <p>The above command is not working (It's not recognizing multiple files) and throwing the error </p>
  
  <pre><code>Error sending message, child exited 67 (User unknown.).
  Could not send the message.
  </code></pre>
  
  <p>Then I tried using multiple <code>-a</code> option as follows,</p>
  
  <pre><code>mutt -s "subject" -a aaa.csv -a bbb.csv -- abc@gmail.com &lt; subject.txt
  </code></pre>
  
  <p><strong>This works as expected.</strong> 
  But this is not feasible for 100 files for example. I should be able use it with file mask (as like *.csv to take all csv files). Is there is any way we can use like *.csv in single command? </p>
  
  <p>Thanks</p>
