Create a script sends an email message to the user specified on the command line if any of the file systems at more than 60% of capacity. The script should not process special file systems as /proc on the ce.uml.edu. It should only process file systems which are either locally mounted or are mounted via NFS.

An individual email should be sent for each filey system which is at the warning level (60%) There should be a subject on the email with a message "Warning: File system here is at % of capacity" If the files system is at greater than 90% of capacity, the "Warning" should be changed to "Critical Warning".

You may use any scripting language including /bin/sh, ksh, bash, awk or perl. Work done in the C-Shell (csh) will not be accepted. The same program for this assignment must be able to be run on both CE.UML.EDU and CYBERSERVER.UML.EDU

Please upload the script for the assigment. Do not upload a Word Document. I may run the script on either or both of the machines to verify your work.

This command -T shows the file system types, so you would only process ufs on this system
