$ mongod --config ${filename}

try on your machine

The command "mongod --config ${filename}" is used to start the MongoDB database server with a specified configuration file.

Here's a breakdown of each component of the command:

"mongod": It refers to the MongoDB server daemon. It is responsible for handling database operations, managing connections, and processing queries.
"--config": This flag is used to specify that a configuration file will be provided to the MongoDB server.
"${filename}": This is a placeholder that represents the name or path of the specific configuration file that you want to use. You would replace "${filename}" with the actual name or path of the configuration file you wish to use.

By using this command, you can start the MongoDB server with a predefined configuration, which includes settings such as database directory, log directory, port number, replication options, security authentication, and various other parameters that affect the server's behavior.
