pv: pv ("Pipe Viewer")
pv:
pv: Pipe Viewer is a tool for monitoring the progress of data through a
pv: pipeline.  It can be inserted into any normal pipeline between two
pv: processes to give a visual indication of how quickly data is passing
pv: through, how long it has taken, how near to completion it is, and an
pv: estimate of how long it will be until completion.
