title: Why is my pipe in Linux getting stuck?
body: <p>I am shelling this: </p>
  
  <pre><code>mkfifo my_fifo
  </code></pre>
  
  <p>with this permission: </p>
  
  <pre><code>prw-r--r--
  </code></pre>
  
  <p>then I do:</p>
  
  <pre><code>echo this is my fifo &gt; my_fifo    
  </code></pre>
  
  <p>but it gets stuck and after ten seconds from another shell the size of <code>my_fifo</code> is zero.</p>
  
  <p>Why is that?</p>
