Answer from AI

Sending commands and data via the command line using cURL is done by specifying various options and parameters in the command line. cURL is a tool for transferring data using various protocols, most commonly HTTP.

Key points:

The URL is specified at the end of the command.
To specify the HTTP method, use -X (e.g., -X POST).
To send data in the request body, use -d or --data.
Headers are passed through -H.

Example of sending a POST request with JSON data:

curl -X POST https://api.example.com/data \
     -H "Content-Type: application/json" \
     -d '{"name":"John", "age":30}'

Thus, through the command line, you can control requests, send data, configure headers, and other parameters for testing APIs or automation.
