title: how can I get sed to quit after the first matching address range?
body: <p>I have a file:</p>
  
  <pre><code>header
  trigger
  text1
  text2
  trigger
  text5
  trigger
  ...
  trigger
  ...
  </code></pre>
  
  <p>I want sed to only match between the first two occurrences of 'trigger'. So I tried:</p>
  
  <pre><code>sed -n '/trigger/,/trigger/p'
  </code></pre>
  
  <p>But as the man page for sed says, that matches all occurrences within two lines with 'trigger'. I want sed to quit after the first match, so the output would be:</p>
  
  <pre><code>trigger
  text1
  text2
  trigger
  </code></pre>
  
  <p>How do I accomplish this?</p>
