title: Reading data from a file using awk
body: <p>I am new at shell scripting and I am trying to read data from a txt file which is in the following format.</p>
  
  <pre><code>A: 1, 2, 3, 4
  
  B: 1,2; 3, 4
  </code></pre>
  
  <p>Here is my code:</p>
  
  <pre><code>awk -F':/,/;/ ' '{ echo $2 $3 $4 $5 $5 }' -f 'testread.txt'
  </code></pre>
  
  <p>I just need the numbers from the text file. 
  Thanks.</p>
