title: Declaring User Defined Variable in Shell Scripting (csh shell)
body: <p>I am trying to learn shell scripting and trying to create a user defined variable within the script, <code>first</code>:</p>
  
  <pre><code>howdy="Hello $USER !"
  echo $howdy
  </code></pre>
  
  <p>However, when I execute the script (<code>./first</code>) I get this:</p>
  
  <pre><code>howdy=Hello aaron!: Command not found.
  howdy: Undefined variable.
  </code></pre>
  
  <p>What am I doing wrong?</p>
