title: Reducing logfiles to just strings of interest
body: <p>I have logfiles containing strings of interest:</p>
  
  <pre><code>ANYTHING*"tested:/DD.MM.YY/directory/FILENAME:worked"ANYTHING*
            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  </code></pre>
  
  <p>How could I select everything besides the strings of interest (including the <code>"</code>s) and delete it?</p>
  
  <p>In the end, I <em>just</em> want lines with the strings of interest, reduced to <em>just</em> the strings of interest.</p>
