Transfers data from or to a server. Supports most protocols, including HTTP, FTP, and POP3. More information: <https://curl.se/docs/manpage.html>.

• Download the contents of a URL to a file:
  curl http://example.com --output path/to/file
• Download a file, saving the output under the filename indicated by the URL:
  curl --remote-name http://example.com/filename
• Download a file, following location redirects, and automatically continuing (resuming) a previous file transfer and return an error on server error:
  curl --fail --remote-name --location --continue-at - http://example.com/filename
• Send form-encoded data (POST request of type `application/x-www-form-urlencoded`). Use `--data @file_name` or `--data @'-'` to read from STDIN:
  curl --data 'name=bob' http://example.com/form
• Send a request with an extra header, using a custom HTTP method:
  curl --header 'X-My-Header: 123' --request PUT http://example.com
• Send data in JSON format, specifying the appropriate content-type header:
  curl --data '{"name":"bob"}' --header 'Content-Type: application/json' http://example.com/users/1234
• Pass a username and prompt for a password to authenticate to the server:
  curl --user username http://example.com
• Pass client certificate and key for a resource, skipping certificate validation:
  curl --cert client.pem --key key.pem --insecure https://example.com
