Script on disk space

[PJenkins]

I have a script that determines filesystem usage. Now I am looking for a script that will alert the user with a displayed message of a file system that goes over a predefined percentage. I was trying to make it so that the percentage is user definable and will show which filesystem has gone over. So far I keep taking steps back instead of forward. Anyone know of a script that will do this? I was trying to get it in ksh or perl.

Not very elegant but this will do it.. Get a sorted list of locally mounted filesystems excluding swap, proc etc. Loop through each one and get the %used less the % sign. Compare with pre-defined warning limit and echo warning if exceeded. You could tailor it further to have a per filesystem warning if you wanted.

#!/usr/bin/ksh
WARNING=40
FILESYSTEMS=`df -k | grep '^/' | grep -v '^/proc' | awk '{ print $6 }' | sort`
for FS in $FILESYSTEMS
do
CAPACITY=`df -k $FS | grep $FS | awk '{ print $5 }' | tr -d '%'`
if [[ $CAPACITY -gt $WARNING ]]
then
echo "${FS} ${CAP}% is over ${WARNING}% full"
fi
done
