title: awk partly string match (if column/word partly matches)
body: <p>My dummy file looks like this:</p>
  
  <pre><code>C1    C2    C3    
  1     a     snow   
  2     b     snowman 
  snow     c     sowman
  </code></pre>
  
  <p>I want to get line if there is string <code>snow</code> in $3. I can do this like this:  </p>
  
  <pre><code>awk '($3=="snow" || $3=="snowman") {print}' dummy_file
  </code></pre>
  
  <p>But there should be more simpler way.</p>
