title: powershell: compare specific columns of CSV files and return entire row of differences
body: <p>I have 2 CSV files I'd like to compare. They both have multiple columns of different data but they also both have a column with IP addresses. Call them $log1 and $log2</p>
  
  <p>I am trying to compare the files. If an IP from $log1 is found in $log2 I would like an output file that has the <em>entire row</em> of data from the match of $log2...  </p>
  
  <p>When I use:</p>
  
  <p><code>Compare-Object -Property 'IP address' -ReferenceObject $log1 -DifferenceObject $log2</code></p>
  
  <p>It returns only the 'IP address' column and the SideIndicator. </p>
  
  <p>I think I'm barking up the wrong tree here, can anyone offer some advice?</p>
