title: sqlplus: password contains slash "/" is not accepted
body: <p>Maybe this is trivial for DB people but unfortunately not for me.</p>
  <p>I spent hours with this but the solutions that I have found did not help. My DB password contains a <code>/</code> character and I think this confuses <code>sqlplus</code> and that is the reason why I am not able to log in. Let's say my password is <code>pass/word</code>.</p>
  <p><strong>This is what I have tried so far:</strong></p>
  <pre><code>$ sqlplus MYUSER/pass/word@ABCDEF
  
  $ sqlplus MYUSER/pass\/word@ABCDEF
  
  $ sqlplus MYUSER/'pass/word'@ABCDEF
  
  $ sqlplus MYUSER/'pass\/word'@ABCDEF
  
  $ sqlplus MYUSER/&quot;pass/word&quot;@ABCDEF
  
  $ sqlplus MYUSER/&quot;pass\/word&quot;@ABCDEF
  
  $ sqlplus MYUSER/\&quot;&quot;pass/word\&quot;&quot;@ABCDEF
  </code></pre>
  <p>None of them above worked.</p>
  <p><strong>Then I tried this way:</strong></p>
  <pre><code>$ sqlplus MYUSER@ABCDEF

  <p>No result.</p>
  <p>Google did not help.</p>
  <p>What is the trick here that I need to use?</p>
