title: sourcing a file containing env variables from ksh
body: <p>I have the following snippet of code:</p>
  
  <pre><code>#!/bin/ksh
  
  source /users/some_user/.cshrc
  </code></pre>
  
  <p>However, running this gives the <code>source:  not found</code> error.</p>
  
  <p>I have also tried using the <code>dot</code> operator like:</p>
  
  <pre><code>#!/bin/ksh
  
  . /users/some_user/.cshrc
  </code></pre>
  
  <p>However, this does not fix the issue either, though it no longer gives me the <code>source: not found</code> error.</p>
  
  <p>What is the correct way to source the <code>.cshrc</code> file?</p>
