body: <p>My file is mentioned below:</p>
  
  <pre><code>[Suresh

  adsfafa
  sdfasdfa
  asdfas
  asdfasdfasd
  [Sala
  sdfadsf
  adsfasd

  </code></pre>
  
  <p>Based on the delimiter <code>"["</code>, I want to separate the lines. I want an output like:</p>
  
  <pre><code>[Suresh asdfala adsfafa sdfasdfa asdfas asdfasdfasd
  
  [Sala sdfadsf adsfasd asdfa wewet
  </code></pre>
