mongodb:query:find

This command uses the mongo command-line interface to execute a MongoDB shell command. The command is executed within the context of a specified MongoDB database.

Here is a step-by-step breakdown of the command:

1. mongo: It is the command to run the MongoDB shell.

2. --eval '<command>': This option allows you to specify a JavaScript command to be executed by the MongoDB shell. In this case, the command being executed is enclosed within single quotes and contains two placeholders (${collection} and ${json_query}).

3. db.${collection}.find(${json_query}): This is the JavaScript command being executed. It performs a database query using the find() method on a specific collection. The values of ${collection} and ${json_query} are replaced with actual values at runtime.

• ${collection} is a placeholder for the name of the collection you want to query. For example, if ${collection} is replaced with "users", it will search for documents in the users collection.

• ${json_query} is a placeholder for a JSON document that specifies the query criteria. It is passed to the find() method as an argument. For example, if ${json_query} is replaced with "{ name: 'John' }", it will search for documents where the name field is equal to "John".

Overall, this command allows you to execute a MongoDB query from the command line by providing the collection and query criteria as arguments.
