title: Escape single and double quote using sed. geed, find, xargs
body: <p>I have a command similiar this this one:</p>
  
  <pre><code>find ./ -type f | xargs gsed -i -r 's/[$][A-Za-z_\'"]/testing
  </code></pre>
  
  <p>I would like put this command to work. Unfortunally the single and double quotes breaks the command. How can I escape this strings and put this command to work?</p>
  
  <p>This question isnt the same as this <a href="https://stackoverflow.com/questions/7517632/how-do-i-escape-double-and-single-quotes-in-sed-bash">one</a> because I have a single quote inside the <strong>[</strong>. But if a littler modification solves the problem works I would like to know.</p>
  
  <p>I had tried several different ways using @, #, \, but no success yet.</p>
