title: Match string and one or more numbers with grep
body: <p>I've got a file <code>myfile</code>. I want to find lines that includes following pattern:</p>
  
  <pre><code>MyWebsite/1234
  </code></pre>
  
  <p>or more general</p>
  
  <p><strong>somecharactersstringswhitespaces</strong>MyWebsite/987<strong>somecharactersstringswhitespaces</strong></p>
  
  <p>There can be 1 or more numbers after <code>MyWebsite</code>.
  I have tried following:</p>
  
  <pre><code>grep ".*MyWebsite[0-9]\{1,\}" myfile
  grep "MyWebsite[0-9]\{1,\}" myfile
  grep MyWebsite"[0-9]\{1,\}" myfile
  grep -E ".*MyWebsite/[0-9]\{1,\}.*" myfile
  </code></pre>
  
  <p>None of them worked, even if intuition and logic says that should be good.</p>
