Problems with an if/then loop within a script

Hi there,

I have written a script to clear out log files from the var/tmp dir. It works up to a point. What I needed to do was to exit the script if there was no files to be deleted. I can get this working on a test script but when I implement it into my program it errors out with a `then` not matched error. I have traced it to the line in the script: if [TEMP ="0"]; then

Could somebody have a look at it and teel me where I have went wrong or point me in the right direction

Here is the extract from the script that I created:

#!/bin/sh
#
# Set local variables
USER=`/usr/bin/whoami`
ACCOUNT=specs
HOSTNAME=`/usr/bin/hostname`
DATE=`/usr/bin/date "+%Y%m%d"`
TEMP=`find /var/tmp/ -name "gem*" -atime +3 | wc -l`
TEMPALL=`find /var/tmp/ -atime +3 | wc -l`
# Purge old Log Files
find /users/agaff/nospace/logs/ -name "*.txt" -atime +1|xargs rm -f
# Main Screen
clear
echo "<1> Delete GEM log files on host: " $HOSTNAME
echo "<2> Delete ALL Files in the /var/tmp ( maintenance only ) "
echo "<3> Exit - no files to be deleted"
echo ""
echo " Enter 1 or 2 or 3"
read ANSWER
if [ $ANSWER = "1" ]; then
clear
echo "Examining Log Files for host: " $HOSTNAME
echo ""
if [ $TEMP = "0" ]; then #(this is where it bombs out)
echo
echo
echo"***************************************************"
echo "There are no log files to be deleted from host:" $HOSTNAME
echo
elif [ $TEMP > "0" ];
then
echo "***********************************************"
echo "There are " $TEMP "log files that can be deleted from host:" $HOSTNAME
echo ""
echo ""
echo "<1> Delete GEM log files on Host" $HOSTNAME "in the /var/tmp directory"
echo "<2> Exit - no files to be deleted"
echo ""
echo " Enter 1 or 2"
echo""
read ANS1
if [ $ANS1 = "1" ]; then
clear
echo ""
echo ""
echo"Deleting GEM Logfiles Log Files"
mkdir -p /users/agaff/nospace/logs/
find /var/tmp/ -name "gem*" -atime +3 > /users/agaff/nospace/logs/$DATE"-"$HOSTNAME"-logs".txt| xargs -f >/dev/null 2>&1
echo ""
echo "************************************************************************"
echo "Tmp Logs are now deleted and logfile updated"
echo ""
echo ""
elif [ $ANS1 = "2" ]; then
echo "Exiting"
else
echo "Invalid selection, exiting..."
exit
