title: Sed match exact
body: <p>I'm currently using <code>'s/string/new_string/g'</code> to go through some CSV files, however I'm running into difficulty in the following scenario:</p>
  
  <p>I want to replace instances of <code>'192.168.0.11'</code>, however it's also catching instances of <code>'192.168.0.111'</code>.</p>
  
  <p>How can I ensure sed only grabs <code>'192.168.0.11'</code> and not <code>'192.168.0.111'</code>? I'll obviously have to repeat this for many variables, so something easily scalable would be appreciated.</p>
  
  <p>Thanks! </p>
