title: 'unknown option -W' error when running mysqldump
body: <p>I am trying to create a backup of a database.</p>
  
  <pre><code>mysqldump -u ost-v1-11-x -xWt1z0*8 ost-v1-11-x_ &gt; /master-db/ost-v1-11-x__.sql
  </code></pre>
  
  <p>But this results in an error:</p>
  
  <pre><code>mysqldump: unknown option '-W'
  </code></pre>
  
  <p>I have verified all of the paths / names / password.</p>
  
  <p>I can use the same code to successfully backup another database on the same server and within the same user account.</p>
  
  <p>I have tried Googling the '-W' error to no avail.</p>
