title: What do the numbers in rsync's output mean?
body: <p>When I run <code>rsync</code> with the <code>--progress</code> flag, I get information about the transfers as follows.</p>
  
  <pre><code>path/to/file
            16 100%    0.01kB/s    0:00:01 (xfer#10857, to-check=427700/441502)
  </code></pre>
  
  <p>What do the numbers in the second row mean? I know what some of them are, but what do the others mean (marked with ??? below)?</p>
  
  <blockquote>
    <p>16 ???</p>
    
    <p>100% amount of transfer completed in this file</p>
    
    <p>0.0.1kB/s speed of current file transfer</p>
    
    <p>0:00:01: time elapsed in current file transfer</p>
    
    <p>10857 count of files transferred</p>
    
    <p>427700 ???</p>
    
    <p>441502 ???</p>
