Recently I found a very useful utility called `pv` (for "pipe viewer"). [Here](http://www.ivarch.com/programs/pv.shtml) is its home page, and it can be easily installed with `brew`. According to its man page,
> `pv` shows the progress of data through a pipeline by giving information such as time elapsed, percentage completed (with progress bar), current throughput rate, total data transferred, and ETA.
