Answer 1

You can do...

(你可以做...)

JS (shell):

(JS（shell）：)

db.getCollectionNames()

node.js:

(Node.js的：)

db.listCollections()

non-JS (shell only):

(非JS（仅限shell）：)

show collections

The reason I call that non-JS is because:

(我称之为非JS的原因是：)

$ mongo prodmongo/app --eval "show collections"
MongoDB shell version: 3.2.10
connecting to: prodmongo/app
2016-10-26T19:34:34.886-0400 E QUERY    [thread1] SyntaxError: missing ; before statement @(shell eval):1:5

$ mongo prodmongo/app --eval "db.getCollectionNames()"
MongoDB shell version: 3.2.10
connecting to: prodmongo/app
[
    "Profiles",
    "Unit_Info"
]

If you really want that sweet, sweet show collections output, you can:

(如果你真的想要甜蜜，甜蜜的show collections输出，你可以：)

$ mongo prodmongo/app --eval "db.getCollectionNames().join('
')"
MongoDB shell version: 3.2.10
connecting to: prodmongo/app
Profiles
Unit_Info
