#Give execute permissions and run this shell script. This script is supposed to notify the root user by email if there are any potential partition size issues.
#Issue the follow command: <b><code><span style="color:#3366CC;font-size:1.2em;">mail</span></code></b>. Check to see if there are any mail messages.
