我如何在Mongodb中执行“显示”语句

Question

What command shall I use when I want to know what databases are in mongodb and what collections are in a database (equals to show tables statement in SQL )? 当我想知道mongodb中有哪些数据库以及数据库中有什么集合（等于在SQL中show tables语句）时，应该使用什么命令？ I only found {dbStats:1} in docs that can only show information about current database without a list of collections. 我在文档中仅发现{dbStats:1}该文档只能显示有关当前数据库的信息，而没有收集列表。

Answer 1

see the official document : 见官方文件：

show dbs            displays all the databases on the server you are connected to
use db_name         switches to db_name on the same server
show collections    displays a list of all the collections in the current database

Answer 2

It's show dbs and show collections : 它是show dbs和show collections ：
