title: Extract a line with a string with double quote by using findstr
body: <p>First of all thank you for this site, I'm a terrible coder and so i need your help with making a batch script, i try to extract only lines that contains Copy " in that line from a text file by using findstr which actually works without that whitespace and double quote. But it will extract the line with "Copy and Help" too which i don't need.</p>
  
  <p>Example:</p>
  
  <p>My text contains (source.txt)</p>
  
  <pre><code>a
  asd Copy and help with these command prompt:
  a
    asd Copy "c:\.." a b c(white space)
  a
   asd Copy and help with these command prompt:
  Copy "d:\.." a c c(tab space)
  avs
      Copy "e:\.." a a c
  vvddf</code></pre>
  
  <p>Output file (op.txt) (should be)</p>
  
  <pre><code>Copy "c:\.." a b c
  Copy "d:\.." a c c
  Copy "e:\.." a a c</code></pre>
  
  <p>After my original code I tried to use<pre><code>findstr /c:"Copy ^"" > op.txt</code></pre>but this doesn't work. To let the findstr know to search a line containing <pre><code>Copy "</code></pre> Copy[whitespace][double quote]</p>
  
  <p><em><strong>Updated section</em></strong></p>
  
  <p>First off my required batch script is working from help by foxidrive. There is still some tweak to do, but i will post it as another question. This question is answered.</p>
  
  <p>This is my updated code for now.</p>
  
  <pre><code>@ECHO OFF
  SETLOCAL ENABLEDELAYEDEXPANSION
  SET source="details.txt"
  IF EXIST %source% (
    FIND /i "copy " &lt;%source% |FIND "\" &gt;op.txt
  ) ELSE (
    Exit
  )
  </code></pre>
  
  <p>Thanks foxidrive for the start off and solving my first issue.</p>
