You didn't specify your OS and the output of df varies from system to system.

Many OS support a -P (POSIX output format) and this is my best bet at getting something working for you:

Code:
df -P | awk 'NR != 1 { sub("%",""); print $5, $6}'| while read PERC FILESYSTEM
do
# Test each FILESYSTEM PERCentage against it's threshold amount.
# If PERCentage is greater than threshold then take action.

case "$FILESYSTEM" in
    /media/*) ;;
    /) ;;
    /home)  [ $PERC -gt 85 ] && rm -f /home/anandb/*.log ;;
    *) mail -s 'Invalid FILESYSTEM! found' anandbarnabas@your.email<<EOF
             
             Filesystem $FILESYSTEM has been discovered by the Diskmonitor Process. 
EOF
