cli utility that shows the speed of data moving from input to output
pipemeter can be inserted in a shell command between two programs passing data via pipe, or between a file and a program reading from stdin, and show the speed and amount of data that has passed through. If reading from a regular file, or passed a size, a progress meter is also shown.
Command line switches allow tuning of block size and display interval. Size parameters have support for dd style block size specification.
Pipemeter is intended to be very lightweight, with no dependencies.
