title: How to grep exact literal string (no regex)
body: <p>Is there a way to <code>grep</code> (or use another command) to find exact strings, using NO regex?</p>
  
  <p>For example, if I want to search for (literally):</p>
  
  <pre><code>/some/file"that/has'lots\of"invalid"chars/and.triggers$(#2)[*~.old][3].html
  </code></pre>
  
  <p>I don't want to go through and escape every single "escapable". Essentially, I want to pass it through, like I would with <code>echo</code>:</p>
  
  <pre><code>$ echo "/some/file\"that/has'lots\of\"invalid\"chars/and.triggers$(#2)[*~.old][3].html"
  /some/file"that/has'lots\of"invalid"chars/and.triggers$(#2)[*~.old][3].html
  </code></pre>
