What do you call a valid email ?

I would call a valid email

([a-z][A-Z][0-9]) @ ([a-z][A-Z][0-9]) . ([a-z][A-Z][0-9])

I have this code:

Code:

loop_enter_valid_email=1
while test $loop_enter_valid_email = 1
do
        echo "Enter email: "
        read email

        if test $email = valid **************************
        then
                loop_enter_valid_email=0
        else
                echo "Email is invalid"
        fi
done

It is the line, marked with the stars*******

that I dont have

If someone would be so helpful, to give me a line that would fit in there, I would be very happy

and similar code to check if website is valid

Thanks

Are you telling that you are aware of regex syntax but you dont know of grep?

Code:

read email

if echo "${email}" | grep '^[a-zA-Z0-9]*@[a-zA-Z0-9]*\.[a-zA-Z0-9]*$' >/dev/null; then
    echo good
else
    echo bad
fi
