AWK to get columns with non zero values
<p>Any better idea to get columns / fields having non zero values.</p>

<p>Data</p>

<pre><code>      col1 col2 col3 .... col50
      1      0   1         1
</code></pre>

<p>so output should be</p>

<pre><code>    col1  col3 .... col50
    1       1         1
</code></pre>

<p>Edit: Example was wrong, so edited it.</p>
