Pipe Viewer - is a terminal-based tool for monitoring the progress of data through a pipeline. It can be inserted into any normal pipeline between two processes to give a visual indication of how quickly data is passing through, how long it has taken, how near to completion it is, and an estimate of how long it will be until completion.
Additional support is available for multiple instances working in tandem, to given a visual indicator of relative throughput in a complex pipeline
The README explains how to compile and install pv for cygwin.
Know issues: pv can't lock mintty terminal. However it works when running pv from cmd.exe
@shaman4ik pv.exe requires cygwin installed, it's not a native windows app. You can open a ticket or a new discussion.
Thanks for Pvforcygwin, it's good!
pvforcygwin works great
