Check file and if it doesnt exist , exit script

Hi,

Another problem, here is my code

Code:
#!/bin/sh

dir='/opt/apps/script/CSV'
datadir='/opt/apps/script/data'

while : ; do
ls -1rt $dir/*.csv > /dev/null 2>&1
if [ $? -eq 0 ] ;then
cp $datadir/weekly.txt $dir/weekly.csv
else
exit 0
fi
done

before it executes the while do, I would like it to check for a file named daily.txt in /opt/apps/script/data/

check /opt/apps/script/data/daily.txt first, if it exists, proceed, else exit code.something like this I guess?

Code:
#!/bin/sh

dir='/opt/apps/script/CSV'
datadir='/opt/apps/script/data'

-> Check here first, if found, proceed, else exit

while : ; do
ls -1rt $dir/*.csv > /dev/null 2>&1
if [ $? -eq 0 ] ;then
cp $datadir/weekly.txt $dir/weekly.csv
else
exit 0
fi
done

Thanks buddies.Regards Smilie
