title: How to read mainframe file from unix sed command?
body: <p>I am trying to read a mainframe file thru' 'sed' but it's not able to.
  This script is being invoked from mainframe JCL so it has tcsh inbuilt.</p>
  
  <pre><code>sed -n '1,10p' mainframeFile 
  </code></pre>
  
  <p>will yield nothing as it can't read.</p>
