mongodb

MongoDB is a document based (NoSQL) database that runs by default on port 27017.

To connect to it, we should use the mongo shell, currently mongosh.

To show all the database in the instance, use the show dbs command.

To select a database: use <db>

To show all the collections in a database use the show collections commands.

To show contents of all the documents inside a collection use the db.<collection>.find().pretty(). It will pretty print the results.

Example:

mongosh <ip>
Current Mongosh Log ID: 63999d00a5b1f19a65a9d84b

Using Mongosh:          1.6.1
