title: Delete Special Characters From File- Unix
body: <p>I have a file that is supposed to be formatted like this:</p>
  
  <pre><code>   ID     QTY 
  xxxxxxxxx,xxx 
  xxxxxxxxx,xxx 
  xxxxxxxxx,xxx 
  xxxxxxxxx,xxx 
  xxxxxxxxx,xxx 
  </code></pre>
  
  <p>Sometimes comes formatted like this though with the special characters separating the first 9 digits.</p>
  
  <pre><code>xxx,xx,xx,xx,xxx
  xxx/xx/xx/xx,xxx
  xx.xxx.xxxx,xxx
  </code></pre>
  
  <p>I would like to know how to delete any special characters from the entire ID.    </p>
