title: How let cmd output less info
body: <p>I have a batch file, for example: <code>test.bat</code>, there is only one command in it:</p>
  
  <pre><code>echo Hello
  </code></pre>
  
  <p>Then I run it:</p>
  
  <pre><code>D:\cmd\test.bat
  </code></pre>
  
  <p>Then it outputs the result:</p>
  
  <pre><code> //output begin
                       -- This is a blank line, I don't want this
   D:\cmd\echo Hello   -- This is not what I want
   Hello               -- I only want to print this line
                       -- This is a blank line, I don't want neither.
   //output end
  </code></pre>
  
  <p>I only want to print the output of  commands run in the batch file, here is the <code>echo</code> command.</p>
  
  <p>But, there are two blank lines, one is at the head of the result, and the other one is at the end of the result. And the <code>D:\cmd\echo Hello</code> in the result is neither not what i want.</p>
  
  <p>What should I do?  Any help would be great, thanks in advance.</p>
