pv - monitor the progress of data through a pipe

This can be used in place of dd or dcfldd in some cases, such as copying disks or files. It's also useful for including with nc so you can see stats about the flow of that pipe.

Examples

Show the average growth rate of logs

xtail /nail/scribe/buffer/some_service_gnerated | pv -a > /dev/null

Write a disk image to usb

This can be used in place of dd if=file of=/dev/disk

# As root
pv ~hoherd/Downloads/ubuntu-16.04.1-desktop-amd64.iso > /dev/rdisk4
