Shell script monitors partition usage, concurrent mail alerts

The recent use of a partition on the line was too fast, and Nagios did not turn on the monitoring of partition usage, taking a few minutes to temporarily write a script to use first. The usage is relatively simple, directly on the code:

Note: The SendEmail script used in the code is an e-mail program developed by Perl that can be found online or using other email scripts
