title: Append text to the beginning of each line
body: <p>I need to modify a server activity report that I send out to remote users.  Instead of them looking up their clients' license numbers, I now have to append this information to the report sent out each morning.  I know POSH can do this, but I haven't had any formal training with it and I'm only familiar with what I've had to create for specific tasks.</p>
  
  <p>I have a csv file with 2 headers LIC, and CLIENT.  The log file begins each line with a 5-digit number that corresponds to a value in the LIC column.  I need to append the value for CLIENT in the column before it's LIC value.  Does anyone have any ideas about where to start building a function that queries the csv file and creates another log file for my report processor to send out?  Thanks in advance for your time!</p>
  
  <p>The csv looks like:</p>
  
  <pre><code>LIC,CLIENT
  12345,Client1
  54321,Client2
  34251,Client3
  </code></pre>
  
  <p>The log currently looks like:</p>
  
  <pre><code>12345_file.txt,9/11/18,08:15:45
  54321_file.txt,9/10/18,11:46:55
  </code></pre>
  
  <p>I would like the log to look like:</p>
  
  <pre><code>Client1,12345_file.txt,9/11/18,08:15:45
  Client2,54321_file.txt,9/10/18,11:46:55
  </code></pre>
