title: Awkward: Combine two awk statements
body: <p>I have a set of data that looks like this:</p>
  
  <pre><code>foo:123 bar baz
  oof:2983 rab zdo 
  mor:8 eoinn uiemdh
  </code></pre>
  
  <p>and what I'd like to have as result is:</p>
  
  <pre><code>123
  2983
  8
  </code></pre>
  
  <p>Assuming the data is in a file called test.txt, what I currently have is: </p>
  
  <pre><code> awk '{print $1}' test.txt | awk -F: '{print $2}'
  </code></pre>
  
  <p>How can I combine those two statements?</p>
