Pipe viewer

Monitor progress of previously opaque unix commands! If that didn’t get you filled with bile and steam, wait ’til you see this! “Additional support is available for multiple instances working in tandem, to given a visual indicator of relative throughput in a complex pipeline:”

Yep. You know what to do. Download pipe viewer.

pv – 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.

Of course, if you don’t feel like doing it that way, you can just script the function in your favourite shell..
