Several years ago, I subscribed to eoddata.com and deltaneutral.com, each of which offered daily comma separated variable (".csv") files via file transfer protocol ("FTP"), which I believe I mirrored under Linux using wget with "ftp://hostname/file" URL's. Perhaps you could do the same with other tools, such as "curl".
I believe that, back then, at least one of those two stopped providing bid-ask data for US equity options, many of which do not trade in a day, making that part of their data almost useless.
