gjduff, you still there? I'm trying to make the script check every 10 seconds for a new file then update a logfile. Can you see what I'm missing?

Thanks,
alexkav

#!/bin/ksh

LOGFILE=logs/gfiupload.log
NEW=`find . -type f -name "G*" -newer newtime`

while true; do
if
[ -z $NEW ]; then
echo "bombing..." >>$LOGFILE
touch newtime
sleep 10

else
FILE=`echo $NEW | sed -e 's/G//g'`
echo `date +%m%d%Y_%H:%M`: New file found: $FILE >>$LOGFILE
mv newtime oldtime
touch newtime
fi
sleep 10
done
