Here's a wrapper script I've written around Bill's bdfmegs.sh:


#!/usr/bin/sh

typeset -i MAXPCT=95
typeset -i TIMEOUT=1 # number of days to retain LOCKFILE
BDFMEGS=/root/scripts/util/bdfmegs.sh
TEMPFILE=/tmp/check_filesystem_usage.${$}.tmp
LOCKFILE=/tmp/check_filesystem_usage.lck

# rm LOCKFILE if mtime > ${TIMEOUT}, so that duplicate reports will be generated, on occasion
find ${LOCKFILE} -type f -mtime +${TIMEOUT} -print | xargs rm -f 2> /dev/null
[ ! -f ${LOCKFILE} ] && touch ${LOCKFILE}

trap "[ -f ${TEMPFILE} ] && rm -f ${TEMPFILE}" 0 1 2 3 15
${BDFMEGS} -qglP ${MAXPCT} | grep -v '^$' > ${TEMPFILE}

if [ -s ${TEMPFILE} ]
then
$(grep -q -v -f ${LOCKFILE} ${TEMPFILE}) && \
{ grep -v -f ${LOCKFILE} ${TEMPFILE} >> ${LOCKFILE}
mailx -m -s "WARNING! FILESYSTEM(S) OVER ${MAXPCT}% FULL!" root << EOF
File-System Gbytes Used Avail %Used Mounted on
$(cat ${TEMPFILE})

Remember to delete ${LOCKFILE} after freeing up space!
EOF
}
# exit with rc of 1 if any filesystems with utilization > ${MAXPCT} were returned
exit 1
fi

# otherwise, exit with rc of 0
exit 0
