title: How to execute a command for each loop in awk?
body: <p>I'm using awk to split a binary stream and I can get each part into a for loop like this.</p>
  
  <p><code>for(i=1;i&lt;=NF;i++)</code></p>
  
  <p>I don't want to convert each field to text or arguments, but simply pass it directly to a command.</p>
  
  <p>I'm trying to find something like this,</p>
  
  <p><code>for(i=1;i&lt;=NF;i++) system("decode")</code></p>
  
  <p>but this obviously doesn't work. decode receives no input.</p>
  
  <p>How do I get decode to receive each field in the loop?</p>
