There&#x27;s also the pv(1) utility on Linux and OS X Homebrew:<p><pre><code>  DESCRIPTION
  
       pv  shows the progress of data through a pipeline by giving infor-
       mation such as time elapsed, percentage completed  (with  progress
       bar), current throughput rate, total data transferred, and ETA.

       To use it, insert it in a pipeline between two processes, with the
       appropriate options.  Its standard input will be passed through to
       its  standard output and progress will be shown on standard error.
</code></pre>
