MongoDB Shell¶

To learn how to download and install the MongoDB Shell, see Install the MongoDB Shell.

Once you have installed the MongoDB Shell and added it to you system PATH, you can connect to a MongoDB deployment. To learn more, see Connect to a Deployment.

Run the .editor command within the MongoDB Shell to open the editor and manage comprehensive multiline functions:

.editor

// Entering editor mode (^D to finish, ^C to cancel)
const { Writable } = require('stream');

  const myWritable = new Writable({
    write(chunk, encoding, callback) {
      // ...
    },
    writev(chunks, callback) {
      // ...
    }
  });

• Press Cmd/Ctrl + d to finish and run your function.
• Press Cmd/Ctrl + c to cancel and exit without running your function.

When you close the editor, the MongoDB Shell does not save any functions you had entered into the editor.

The MongoDB Shell offers numerous advantages over the legacy mongo shell, such as:

• Improved syntax highlighting.
• Improved command history.
• Improved logging.

During the beta stage, the MongoDB Shell supports a subset of the legacy mongo shell commands. Extending the MongoDB Shell API coverage is an ongoing effort.

The commands that the MongoDB Shell supports use the same syntax as the corresponding commands in the legacy mongo shell.
