title: How to merge specific columns from many files in one file
body: <p>I have 100+ tab separated files in one directory and i want to merge 2nd column from each file to one file.
  I was trying to use <code>paste</code> like this:</p>
  
  <pre><code>paste -d" " *.tsv &gt;&gt; result.tsv
  </code></pre>
  
  <p>It appends everything, i can't figure out how to apply <code>awk '{print $2}'</code> to it. Can anyone suggest how to approach such a task?
  Example input:</p>
  
  <blockquote>
    <p>file1</p>
  </blockquote>
  
  <pre><code>1 2 3 4
  2 3 4 5
  </code></pre>
  
  <blockquote>
    <p>file2</p>
  </blockquote>
  
  <pre><code>3 4 5 6
  5 6 7 8
  </code></pre>
  
  <blockquote>
    <p>file 3</p>
  </blockquote>
  
  <pre><code>7 6 5 6
  2 3 4 4
  </code></pre>
  
  <p>Desired output file:</p>
  
  <pre><code>2 4 6
  3 6 3
  </code></pre>
