I mean a-z.  Still not working.

        # Check for a proper url
        if [[ $DOMAIN = *[!a-z0-9.]* ]] ; then
                echo "Invalid URL  a-b, 0-9 and . allowed only."
                exit 1  
        fi

        # We must escape special characters
        DOMAIN = ${DOMAIN//./\\.}

Check 1 works.  The substitution returns and error (DOMAIN: command not
found).
