Shell Programming and Scripting

Hello Everybody

I recently got this beautiful shell script from my friend. I like to share it with every body as I am bit new to shell scripting enviorment. I hope people in this site will like it. It is related to checking the filesystem threshold limit. After getting threshold limit of particular server filesystems . This script will show amount of filesystem full on the servers listed in a file called Delhosts. This script must be running continously 24*7

Any modification in this shell script is always welcome, to impove it


kind regards to all
