Linux Disk Usage Scripts

Two simple Linux disk usage monitoring scripts that sends an email notification if certain conditions are met. Two scripts utilise both MB Block usage and default disk capacity usage for a particular a POSIX partition. If both are greater than thresholds, then trigger the email alert through the system.

Example

A sample of output for df looks like:

	 example% df
	 Filesystem   kbytes  used  avail  capacity  Mounted on
	 ojd2:/	        7445  4714   1986    70%       /
	 ojd2:/usr     42277  35291  2758    93%       /usr

Both scripts utilise the df -h and the df -M commands which both display both disk usage statistics and MB Block disk usage amount. If either two is greater than or equal to thresholds, some simple methods send email notifications.
