title: Check if file exists on remote machine. If not, then copy it
body: <p>I am very new to powershell and was wondering if anyone could point me in the right direction.</p>
  
  <p>I was looking to write a script that would help me with the following:</p>
  
  <ol>
  <li>I have a file that I need to push to remote machines.</li>
  <li>I have a list of remote computer names that I wish to check to see if the file exsists.</li>
  <li>If the file exists and the size and date are the same, then do nothing.</li>
  <li>If the file does not exist, or the date/size are different, then copy the file.</li>
  <li>I would also possibly like to write to some sort of log/text file to indicate the status, such as "PC1 - no file found. Copying" or "PC2 - exact file found, nothing copied"</li>
  </ol>
