Monitor zfs send and receive (with parallel compression)
Use pipe viewer to monitor progress of a zfs send operation. Parallelizing compression via pigz can significantly reduce run time:
zfs send $1 | pv -c -s $(zfs send -RnP $1 2>&1 | awk '{if ($1 == "size") {print $2}}') | pigz -c > $2.zfs.gz
pv $1 | unpigz -c | zfs receive $2Written by Matt Keranen

Can we get a little more detail on what this script is doing ? the $1 variable are part of a different input with the ZFS snapshot ?

If put in a shell script, $1 is the name of the ZFS snapshot to send, and $2 is the name of the filename the compressed snapshot is stored in (the first and second args passed to the script).
