zfsrepquota

#!/usr/bin/env bash

# Print ZFS filesystem user disk quotas in a format similar to Linux "repquota".
# Used disk space is reported in GBytes.
# Note: ZFS has no concept of "soft quota limits".
# The zfs userspace command is only permitted for the root user, therefore
# copy this script to the /usr/local/sbin/ folder.

# CONFIGURE THIS:
# Defile the quota warning limit (percentage)
export warn_limit=80

# Command usage:
function usage()

        -h: Print this help information
