title: SHELL add double quotes at the beginning and end of specific variable
body: <p>I have variable in shell script which takes a value in variable $var1.
  If I do <code>echo $var1</code> I will get for example value Boston.
  My desired value is <code>"Boston"</code></p>
  
  <p>I tried couple of cases:</p>
  
  <pre><code>var1=""$var1""
  var1="""$var1"""
  </code></pre>
  
  <p>But in both cases I am getting as result <code>'$var1'</code> but I want <code>"Boston"</code>
  Please for solution do not mention solution which contains Boston in it. I would appreciate if you can use only <code>var1</code> in the whole script so it can be more clear! "Boston" just needs to be output of the script execution and for initiliztion for the variable var1.</p>
  
  <p>Thanks</p>
