title: How to append contents of multiple files into one file
body: <p>I want to copy the contents of five files to one file as is. I tried doing it using cp for each file. But that overwrites the contents copied from the previous file. I also tried </p>
  
  <pre><code>paste -d "\n" 1.txt 0.txt
  </code></pre>
  
  <p>and it did not work.</p>
  
  <p>I want my script to add the newline at the end of each text file.</p>
  
  <p>eg. Files 1.txt, 2.txt, 3.txt. Put contents of 1,2,3 in 0.txt</p>
  
  <p>How do I do it ?</p>
