The listDatabases command provides a list of existing databases along with basic statistics about them:
{ listDatabases: 1 }
The value (e.g. 1) does not effect the output of the command. listDatabases returns a document for each database Each document contains a name field with the database name, a sizeOnDisk field with the total size of the database file on disk in bytes, and an empty field specifying whether the database has any data.
