In this context processes are programs that print output and handle
input. They can be connected with pipe and "pv" can be in the middle:
program1 | pv | program2
The data goes unchanged through "pv" but it shows progress information
in the standard error stream. So, "pv" is like "dd" or even "cat", but
better for data transfer monitoring.
See the EXAMPLES section in the man page but I'll give a couple of
useful:
sudo pv /dev/zero -o /dev/targetdrive
sudo pv disc-image.img --sync -o /dev/targetdrive
