cron execution

Hi,

Here is the code snippet when executing on the command line it does execute smoothly, but while i place this on cron it doesnt run.

Can anybody suggest where the problem in cron is.?

#!/usr/bin/ksh

home_dir="/export/home/scripts/MonitorScripts"
ThresholdLimit=5


touch $home_dir/cpuLog.txt
touch $home_dir/pid_Log.txt

#execute TOP command and store results in a Text

top | awk '{print $1, $10}' | grep % > $home_dir/cpuLog.txt
perl -pi -e 's/%/ /g' cpuLog.txt

sleep 10

while read BUFFER

do
row=`echo $BUFFER`
col1=`echo $row | cut -f1 -d ' '`
col2=`echo $row | cut -f2 -d ' '`

if [ $col2 -ge $ThresholdLimit ]; then

/usr/ucb/ps -auuwwx | grep $col1 >> $home_dir/pid_Log.txt
fi

done < cpuLog.txt

checpid=`wc -l $home_dir/pid_Log.txt | awk '{print $1}`

if [ $checpid -ge 0 ]; then
mailx -s "Check for CPU process running on HIGH(above 5%)" -c "" abc@xyz.com < $home_dir/pid_Log.txt
sleep 3
rm $home_dir/cpuLog.txt
rm $home_dir/pid_Log.txt
else
rm $home_dir/cpuLog.txt
rm $home_dir/pid_Log.txt
exit
fi
exit



Here is the cron that is set to.
