  while read partition size used free perc mnt ;
  do
    usep=$(echo $perc | tr -d '%' )
    if [ $usep -ge $ALERT ]; then
      echo "Running out of space \"$partition ($usep%)\" on $(hostname) as
  on $(date)" |
       mail -s "Alert: Almost out of disk space $usep" $ADMIN
    fi
  done


it works for me.
