title: shell to filter prohibited words on a file
body: <p>Good day shell lovers!</p>
  
  <p>basically i have two files:</p>
  
  <p><strong>frequency.txt:</strong> (multiple lines, space separated file containing words and a frequency)</p>
  
  <pre><code>de 1711
  a 936
  et 762
  la 530
  les 482
  pour 439
  le 425
  ...
  </code></pre>
  
  <p>and i have a file containing "prohibited" words:</p>
  
  <p><strong>stopwords.txt:</strong> (one single line, space separated file)</p>
  
  <pre><code> au aux avec le ces dans ...
  </code></pre>
  
  <p>so i want to delete from <em>frequency.txt</em> all the lines containing a word found on <em>stopwords.txt</em></p>
  
  <p>how could i do that? i'm thinking that it could be done with awk.. something like</p>
  
  <pre><code>awk 'match($0,SOMETHING_MAGICAL_HERE) == 0 {print $0}' frequency.txt &gt; new.txt
  </code></pre>
  
  <p>but i'm not really sure... any ideas?? thxs in advance</p>
