title: Using Awk to remove whitespace
body: <p>I have a file in the form of:</p>
  
  <pre><code>Firstname LastName; 123-4567; Job Title
      Firstname LastName;   123-4567;      Job Title
  Firstname LastName;      123-4567; Job Title
  ...
  </code></pre>
  
  <p>I am trying to use awk to parse the file into a form readable by makedbm (to make a custom NIS map).  Field separator is a semicolon.  I need to be able to remove all leading whitespace from each field on each line, but leave the spaces in the name field and the title field.  Thanks.</p>
