Looping Resilver Monitor

#!/bin/bash

# A simple looping script to display the
# resilvering progress of a specific pool.
# Idea came from Technicus, and lots of Googling!
# Ctrl + C to kill the script


# Specify the name of the pool to monitor. Case sensitive!

POOL=Pool_Name_Here

# Define how often, in seconds, that the
# screen refreshes. Decimals do work, but 1-2 seconds
# should work best

INTERVAL=2
