title: Print filename and columns with awk
body: <p>I would like to select the column 23,24 and 27 of the 8th row. </p>
  
  <p>Here is the way I have tried. </p>
  
  <pre><code>awk 'FNR == 8 {print $23,$24,$37}' file.txt
  </code></pre>
  
  <p>It works perfectly. 
  However, I'm wondering how to add the corresponding file name as the $0</p>
  
  <p>Then, the output should look like</p>
  
  <pre><code>file.txt colunm23 colunm24 colunm 27     &lt;---- The 8th row.    
  </code></pre>
  
  <p>I'm not using gawk. Please suggest based on the version before gawk 4.0.0
  Thank you. </p>
