mongosh
Start mongosh against a connection URI, then use show dbs, use <db>, and show collections to move around the server.
mongosh is the modern MongoDB shell; you launch it with a connection string like mongodb://localhost:27017.
Once connected, show dbs lists the databases and use <db> sets the one your commands operate on.
show collections then reveals the collections inside the current database so you know what you can query.
01
mongosh <uri> opens the shell.
02
show dbs lists databases.
03
use <db> switches the current database.

show collectionsRead the implementation
Connect each part of the code to the concept before you type.
2. List databases
show dbs lists the databases on the server along with their on-disk size.
show dbs3. Switch database
use <db> selects the current database; the named db is created lazily on first write.
use shop4. List collections
show collections lists the collections inside the database you are currently using.
