title: Linux/Bash: How to unquote?
body: <p>Following command</p>
  
  <pre><code>echo 'a b' 'c'
  </code></pre>
  
  <p>outputs</p>
  
  <pre><code>a b c
  </code></pre>
  
  <p>But the following</p>
  
  <pre><code>X="'a b' 'c'"
  echo $X;
  </code></pre>
  
  <p>will outout</p>
  
  <pre><code>'a b' 'c'
  </code></pre>
  
  <p>I am searching a way to unquote $X , so that it will output "a b c" , but without losing the merged 'a b' argument. (= 2 arguments instead of 3, makes no difference for command 'echo', but for other commands like 'cp')</p>
