Shell script to notify Hard disk space utilization

The below script will check the hard disk space usage, using the command du and send an email alert if any of the partition is using more than 85% of space.

vim disk-usage.sh

#!/bin/sh

df -H | grep -vE '^Filesystem|tmpfs|cdrom' | awk '{ print $5 " " $1 }' | while read output;

do

  echo $output

  usep=$(echo $output | awk '{ print $1}' | cut -d'%' -f1  )

  partition=$(echo $output | awk '{ print $2 }' )

  if [ $usep -ge 85 ]; then

    echo "Running out of space \"$partition ($usep%)\" on $(hostname) as on $(date)" |

     mail -s "Alert: Almost out of disk space $usep%" example@example.com

  fi

done

Set a cronjob to run this script.
