I'll add 'pv' to the list. Great way to watch progress if you are using zcat/cat to pipe something somewhere.

For example, got a database dump? 'cat db.sql | pv | yoursqlengine'

If you do that, pv does NOT know how big the input is, and you are wasting a pipe and a process. 'pv db.sql | yoursqlengine' on the other hand would work great.

You get a nice progress bar and estimation of time to complete, autoscaling speed. Lots of other options too.
