Hi ALL

#!/bin/sh # Shell script to monitor or watch the disk space # It will send an email to $ADMIN, if the (free avilable) percentage # of space is >= 90% # ------------------------------------------------------------------------- # Copyright (c) 2005 nixCraft project http://cyberciti.biz/fb/ # This script is licensed under GNU GPL version 2.0 or above # ------------------------------------------------------------------------- # This script is part of nixCraft shell script collection (NSSC) # Visit http://bash.cyberciti.biz/ for more information. # ---------------------------------------------------------------------- # Linux shell script to watch disk space (should work on other UNIX oses ) # SEE URL: http://www.cyberciti.biz/tips/shell-script-to-watch-the-disk-space.html # set admin email so that you can get email ADMIN="me@somewher.com" # set alert level 90% is default ALERT=90 df -H | grep -vE '^Filesystem|tmpfs|cdrom' | awk '{ print $5 " " $1 }' | while read output; do #echo $output usep=$(echo $output | awk '{ print $1}' | cut -d'%' -f1 ) partition=$(echo $output | awk '{ print $2 }' ) if [ $usep -ge $ALERT ]; then echo "Running out of space "$partition ($usep%)" on $(hostname) as on $(date)" | mail -s "Alert: Almost out of disk space $usep" $ADMIN fi done

Am trying to run the above script on my machine, it gave the following error [root@linux8 script]# ./disk_monitor.sh ./disk_monitor.sh: line 23: [: /dev/mapper/VolGroup00-LogVol00: integer expression expected ./disk_monitor.sh: line 23: [: /: integer expression expected

Any help?
