Here is a handy script in my collection:

#!/bin/ksh
#
# fswarn.ksh - checks the filesystem usage and mail alert
# if any match alarm threshold

fswarnLog=/cust/utils/fswarn/fswarn.log
mailProg=mailx
alarm=90
prog=$(basename $0)

df -k | while read line
do
if echo $line | grep '^Filesystem' >/dev/null
then
continue
fi
set $line
pcntFull=$(echo $5 | sed 's/%//')
fs=$6
if [[ "$pcntFull" -gt "$alarm" ]]
then
# send warning to logfile and mail to the admin
echo "WARNING: $fs is $pcntFull percent full at $(date)" >> $fswarnLog
echo "WARNING: $fs is $pcntFull percent full at $(date)" | $mailProg email@domain.com
fi
done
