What You Can Do

Find your connection string. The connection string varies depending on the type of deployment you're connecting to.

Learn how to find your connection string forAtlas.

Or connect to aself-hosteddeployment.

Connect to a MongoDB deployment using the connection string.

The following connection string connects to an Atlas deployment:

mongosh "mongodb+srv://mycluster.abcd1.mongodb.net/myFirstDatabase" --apiVersion 1 --username <username>

Use your chosen connection type to view your data, import documents, and run queries.

For more information, refer to Perform CRUD Operations.

View information about databases, create collections or views, or drop databases - all from your shell. See allDatabase Methods.

Perform collection operations, create or delete indexes, or explain queries with Collection Methods.

Write scripts to run with the MongoDB Shell that perform CRUD or administrative operations in MongoDB.

For example, if you have a JS file that seeds synthetic or mock data into MongoDB in your development or staging environment, run the file with:

mongosh YOUR_JS_FILENAME.js

Explore a tutorial that uses the MongoDB Shell with JavaScript to access MongoDB: Write Scripts.

Repeatedly writing large helper functions in the Shell? Store them in a .mongoshrc config file. For example, if you often find yourself converting date strings to ISO format for queries, create a function in .mongoshrc to handle it:

function toISO(dateString) {

   return new Date(dateString).toISOString();

}

Then, call the function in mongosh:

db.clientConnections.find( { connectTime: toISO("06/07/2017") } )

For more information, refer to Execute Code From a Configuration File.
