So proud of my disk size monitoring script, so I'm just going to share it here as-is:

#!/bin/bash
# diskspace.sh
# Set up the mountpoint
MOUNTPOINT="/mnt/somethingsomething"

# Get disk usage and total
DISK_USAGE=$(df -hk | grep "$MOUNTPOINT" | awk '{print $3}')
DISK_TOTAL=$(df -hk | grep "$MOUNTPOINT" | awk '{print $2}')

# Convert from block sizes to GB
DISK_USAGE_GB=$((DISK_USAGE / 1024 / 1024))
DISK_TOTAL_GB=$((DISK_TOTAL / 1024 / 1024))

# How much is allowed to be left
DISK_GB_LIMIT="8"

# How much is left
DISK_GB_LEFT=$((DISK_TOTAL_GB - DISK_USAGE_GB))

if [ "$DISK_GB_LEFT" -lt "$DISK_GB_LIMIT" ]; then
echo "Less than ${DISK_GB_LIMIT} GB left! Only ${DISK_GB_LEFT} GB left!"
else
echo "There is still ${DISK_GB_LEFT} of ${DISK_TOTAL_GB} GB left. No need to be alarmed as the alarming limit is ${DISK_GB_LIMIT} GB."
