title: how to send a mail with a message in unix script
body: <p>New to unix and learning the talk and walk of it.
  I am writing a script in .ksh and have a requirement of sending a mail with a message.
  Currently using this command in my script:</p>
  
  <pre><code>    mailx -s"File not found" abc@def.com
  </code></pre>
  
  <p>This command helps me having a subject and the recipient name.
  My question is how can I write a message along with it. Cause every time i run the script it pauses and asks me to enter the message and then executes, I want to pre-include the message so the script would not pause in between. </p>
