title: Merging CSV files : Appending instead of merging
body: <p>So basically i want to merge a couple of CSV files. Im using the following script to do that : </p>
  
  <pre><code>paste -d , *.csv &gt; final.txt
  </code></pre>
  
  <p>However this has worked for me in the past but this time it doesn't work. It appends the data next to each other as opposed to below each other. For instance two files that contain records in the following format</p>
  
  <pre><code>CreatedAt   ID
  Mon Jul 07 20:43:47 +0000 2014  4.86249E+17
  Mon Jul 07 19:58:29 +0000 2014  4.86238E+17
  Mon Jul 07 19:42:33 +0000 2014  4.86234E+17
  </code></pre>
  
  <p>When merged give </p>
  
  <pre><code>CreatedAt   ID CreatedAt    ID

                                              Mon Jul 07 15:34:13 +0000 2014  4.86176E+17
  </code></pre>
  
  <p>Would anyone know what the reason behind this is? Or what i can do to force merge below records? </p>
