Disk usage notifier

Shell script to send an email notification to the specific email address when disk is used up to the specified percentage.

The shell script is tested on Ubuntu OS.

For the proper functioning of the script, we have to install mail sender on the system. I have followed the link below: https://linuxconfig.org/configuring-gmail-as-sendmail-email-relay

After mail sender configuration, configure crontab to run script hourly basis. Use command crontab -e

Now email will trigger when the system uses the specific percentage of disk space usage.

This notifier checks all the partitions specified for specified disk usage percentage.
