title: Using awk to print characters of specific index on a line
body: <p>Alright, so I know it is quite simple to print specific arguments of a line using $: </p>
  
  <pre><code>$ cat file
  hello world
  
  $ awk '{print $1}' file
  hello
  </code></pre>
  
  <p>But what if I want to print chars 2 through 8? or 3 through 7? Is that possible with awk? </p>
