Export one object with mongoexport, how to specify _id?

Question

I\'m trying to export just one object with mongoexport, filtering by its ID.

I tried:

mongoexport -d \"kb_development\" -c \"articles\" -q \"{\'_id\'

I think you should be able to use ObjectId(...) in the query argument to mongoexport:

mongoexport -d kb_development -c articles -q '{_id: ObjectId("4e3ca3bc38c4f10adf000002")}'

If that does not work, you can use the "strict mode" javascript notation of ObjectIds, as documented here:

mongoexport -d kb_development -c articles -q '{_id: {"$oid": "4e3ca3bc38c4f10adf000002"}}'

(Also note that strict mode JSON is the format produced by mongoexport)
