title: Couple questions about using Rsync?
body: <p>I can't find any reliable file syncing program for my Mac, so I have been using the command line Rsync between two folders.</p>
  
  <p>I have been using "rsync -r source destination".</p>
  
  <p>-Does this sync files both ways, or only sync the source to the destination?
  -If a file was previously synced between the two folders, but deleted because it is no longer needed, does it get deleted on both the source and destination, or will it just always get copied to where it is missing from?</p>
