case $name in
     *[!a-zA-Z ]*) echo invalid name ;;
     *) echo OK ;;

thank you for your reply cfajohnson but joe smith was just a example of input to run the script ./book.sh i want to be able to add any name or number to the ./book.sh script so i am not sure how to change your idea so i can use positional paramiters to run the script $1 $2 for name and number.
