title: Awk if lower than 0
body: <pre><code>awk -F, '$2&gt;0 {print $1}' file.csv
  </code></pre>
  
  <p>This return nothing.</p>
  
  <pre><code>awk -F, '$2&lt;0 {print $1}' file.csv
  </code></pre>
  
  <p>This returns everything.</p>
  
  <p>What I want is if $2 has a value lower than 0, I want the name in $1.
  Same for if higher than 0.</p>
  
  <p>To sum up, I want to split my list in two; higher and lower than zero.</p>
