title: How to remove linebreaks and replace them with a comma in Notepad++
body: <p>I need some help in Notepad++ and regular expressions.</p>
  
  <p>Example how it looks at the moment:
  </p>
  
  <pre class="lang-none prettyprint-override"><code>aaaaa
  bbbb
  cccccc
  </code></pre>
  
  <p>How I want it (remove breakpoints and replace them with a comma and a blank space):</p>
  
  <pre class="lang-none prettyprint-override"><code>aaaaa, bbbb, cccccc
  </code></pre>
  
  <p>I was told that I can do it by checking "Regular expression" and "matches newline" and;</p>
  
  <pre class="lang-none prettyprint-override"><code>Find what: "[\r\n]+"
  
  Replace with:","
  
  -&gt; Replace All
  </code></pre>
  
  <p>However I can't find the "matches newline" in my Replace window. Do I need any plugins for it? The version of my Notepad++ is 5.7 (UNICODE). </p>
