title: Fuse two csv files
body: <p>I am trying to fuse two csv files this way using BASH.</p>
  
  <p>files1.csv :</p>
  
  <pre><code>Col1;Col2
  a;b
  b:c
  </code></pre>
  
  <p>file2.csv</p>
  
  <pre><code>Col3;Col4
  1;2
  3;4
  </code></pre>
  
  <p>result.csv</p>
  
  <pre><code>Col1;Col2;Col3;Col4
  a;b;0;0
  b;c;0;0
  0;0;1;2
  0;0;3;4
  </code></pre>
  
  <p>The '0's in the result files are just empty cells.
  I tried using paste command but it doesn't fuse it the way I want.</p>
  
  <pre><code>paste -d';' file1 file2 
  </code></pre>
  
  <p>Is there a way to do it using BASH?</p>
  
  <p>Thanks.</p>
