title: How can I make the list of letters from A to Z and iterate through them in the shell?
body: <p>Say I want to iterate from letter A to letter Z in csh shell. How do I succinctly do that?</p>
  
  <p>In bash I would do something like  </p>
  
  <pre><code>for i in 'A B C ...Z'; do echo $i; done
  </code></pre>
  
  <p>The point is I don't want to write A through Z, I want something like </p>
  
  <pre><code>[A-Z]
  </code></pre>
  
  <p>Can you suggest a one line suggestion in AWK or Perl?</p>
