Hi
I have been trying every possible solution available for this error on this Forum but could not resolve it.

When i am running the below script i get this error.:mad:

sh diskMonitor.sh
diskMonitor.sh[23]: -: 0403-053 Expression is not complete; more tokens expected.
diskMonitor.sh[23]: -: 0403-053 Expression is not complete; more tokens expected.

The Verison of Unix is : AIX 6.1

The Script is to monitor disk space and send alert mail.

Code is :

#!/usr/bin/ksh
#This script monitors available disk space.
# This script emails an alert when a locally mounted partition crosses a given threshold.
# Set your threshold percentage (do not include the % sign), email address, and excluded mount points, then add to crontab
#
# Add this to crontab -e for root
# Diskspace monitoring script
#0 6 * * 1-5 /bin/diskMonitor.sh >/dev/null 2>&1

THRESHOLD="99"
EMAIL="abe@atred.com"
HOSTNAME=`hostname`

# Excluded mount points *must* be pipe delimited
# "/proc|/export/home|Mounted" should always be included

EXCLUDE="/proc|/export/home|Mounted"

df -k | awk '{print $7"\t"$4}' |egrep -v "(${EXCLUDE})" | while read LINE; do
PERC=`echo $LINE |awk '{print $2}' | cut -d"%" -f1`
Path=`echo $LINE |awk '{print $1}'`

if [ $PERC -gt THRESHOLD ];
then
echo "*****ALERT on $HOSTNAME Disk Space Exceeded the Threashold.Current Usage is  ${PERC}% on path  ${Path} Please perform C
lean Up*****" | /usr/bin/mailx -r xrt@avft.com -s "ALERT `hostname`: Disk Space Alert: ${LINE} used " $EMAIL
fi
done

FYI

The Script is working and sending mail. Its doing what it should but with these two o/p error message which i want to get rid of ASAP so i can cron them.

First you have a missing $ in if
second what done $PERC holds?

if [ $PERC -gt $THRESHOLD ] ;

No, That is not the issue.
It was a typo.
There is a $ in THRESHOLD vairable.
and $PERC hold the Percentage used by the file system

Try to use variable names in small case letters as uppercase might lead into some shell internal variable and throw error like THRESHHOLD.. (I may not be 100% correct here worth a try)

Hi,

Use quote when you compare variables in case one is empty;

So use :
