title: How to delete everything before a variable number with Perl/Regex
body: <p>I'm cleaning a file with Perl and I have one line that is a bit tough to work with.</p>
  
  <p>It looks something like:</p>
  
  <pre><code>^L#$%@@$^%^3456 [rest of string]
  </code></pre>
  
  <p>but I need to get rid of everything before the <code>3456</code></p>
  
  <p>the issue is that the <code>3456</code> change every single time, so I need to use a sed command that is non specific. I should also add that the stuff before the <code>3456</code> will never be numbers</p>
  
  <p>now <code>s/^.*$someString/$someString/</code> works when i'm working with strings, but the same line doesn't work when it's not a string.</p>
  
  <p>anyway, please help!</p>
