-- To reply to myself: Having looked at the "file" db pattern source
[1], I see that the "file" maintainer introduced a typo into the
matching pattern for correctly identifying Classification records.
That's way it's failing for Class records.
Over and out,

Don't know if you consider these "bulk," but there is more than 1 record in each file
(caveat: "file" stops after evaluating the first line, so of the 2,574 Auth records, the
last 2,573 could be invalid). It failed on a file containing all of LC Classification. I need to
figure out why.
Kevin, do you have examples of the output?
-- I received "MARC21 Bibliography" and "MARC21 Authority" respectively. In theory, if Leader
20-23 are not "4500" then "(non-conforming)" should be appended to the identification. If
requested, the mimetype - application/marc - should also be outputted.

Wow, this is pretty cool.

I mean, I could just try this on my Ubuntu machine, but it's all the

I finally had occasion today (read: remembered) to see if the *nix
"file" command would recognize a MARC record file. I haven't tested
extensively, but it did identify the file as MARC21 Bibliographic
record. It also correctly identified a MARC21 Authority Record. I'm
running the most recent version of Ubuntu (12.04 - precise pangolin).
I write because the inclusion of a "file" MARC21 specification rule
in the magic.db stems from a Code4lib exchange that started in March
2011 [1] (it ends in April if you want to go crawling for the entire
thread).
