Bash regex test not working

Question

echo "Enter username"
read $WORD

if [[ "$WORD" =~ ^(Dale|Paul|Ray)$ ]]; then
    echo "$WORD is valid"
else
    echo "$WORD is invalid"
fi

I did format it like that, for some reason when I typed it here it changed. But it still doesn't work. — Maria C, 18 hours ago

The error is in read command, use read WORD instead of read $WORD.

Check this:

echo "Enter username"
read WORD

if [[ "$WORD" =~ ^(Dale|Paul|Ray)$ ]]; then
    echo "$WORD is valid"
else
    echo "$WORD is invalid"
fi
