What is not working ie. what is the error output?
Is this written for a df -k on your Linux box?
Some Unix'es/Linux'es have different positions for their Used%.

Please tell exactly what the problem is - do you get garbled output? Maybe comment out the line where it is sent as mail and redirect to a file or check your output on the screen.

What you can do is remove few lines from code. and type on shell set -x on.
when you run it ... you will see what is the script in action ...

if [ -s ${FILE2} ]; then
mail -s "Filesystem threshold reached" prakash.gr@youtelecom.com < ${FILE2}
fi
rm ${FILE1}
rm ${FILE2}

Give me output of the command :

df -k

And also which mount point are you interested in monitoring..

Your script says no Mount point is above 90% .. if you need a mail to check ... change the 90% in your script to 1% or less :slight_smile: ... You will get a alert email ...
