最终

str= this "'is shell'" script "'to learn'"

Answer 1

echo $str | perl -pe "s|'(.*?)'|\"'\1'\"|g"

Answer 2

尝试一下

<div class="table-responsive">
  <table id="http_response" class="table table-bordred table-bordred table-striped">
    <thead>
      <th>Response</th>
    </thead>
      <tr>
        <td>Mac</td>
        <td>Parameter Name</td>
        <td>Response</td>
      </tr>
      </table>
    </div>

   //JS FIle
    var tr;
  tr = $('<tr/>');
  tr.append("<td>" + mac + "</td>");
  tr.append("<td>" + result["response"].parameter_name + "</td>");
  tr.append("<td>" + result["response"].status + "</td>")    

$('#http_response').append(tr);
