Need Help to deal with empty string

Hi one to All

i have written the code for searching the string in the file for specified path. its working fine,

but my req:if the string is not available in the file , it should display the Message saying that , string is not available in the file.

code is:
echo "give the path where we can search the file and the string"
read path
echo -e "Give your inputs here, first filename, followed by the string with a space"
read -a file_string
echo "========================================================================"
echo -e "Here is your required output \n"
for i in `find "$path" -name "${file_string[0]}*"`;do cat $i | grep -i ${file_string[1]};done

Till now its working fine , but when the string is not available in the file it should display the message.

Thanks
Saic
