im using a grep statement

grep -w "$cars" $carsfile

but it says no such file or directory tried the -f option to
if the value of the '$carsfile' variable point to the non-existing file, then it's what it is - the file you're trying to search doesn't exist.
You need to debug your script - include the 'set -x' at the top of your script and see the debug tracing.

            echo "Exitting."
            exit;;
        *)    echo "Please, choose a valid option!";;
    esac
done

In the above after pressing option 1, after everything is done in that part how would i get it to display all the options again so user can choose another option?
