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\'

My MongoDB verion: 3.2.4. when I use mongoexport tool in mongo shell：

NOT WORK:

-q '{"_id":ObjectId("5719cd12b1168b9d45136295")}'

-q '{_id: {"$oid": "5719cd12b1168b9d45136295"}}'

WORKs:

-q "{_id:ObjectId('5719cd12b1168b9d45136295')}"


- Though in mongo doc , it says that

You must enclose the query in single quotes (e.g. ') to ensure that it does not interact with your shell environment.

- But, single quote(') does not work! please use double quote(")!
