Following is a list of mostly used cURL utility options used by CouchDB:

-X flag: While communicating with an HTTP server, -X flag facilitates users to specify a request method (GET, POST, PUT etc.) to override the default method(GET).

While communicating with an FTP server, -X flag facilitates users to specify FTP command to override the default command(LIST).

-H: The H flag specifies a custom header to pass on to the server.

For example: If you send a file to the server, you have to use the "content type" that defines the type of content of the file that you want to upload.

-d flag: This flag is used to send data along with the HTTP POST request to the server as it is filled by the user in the form and submitted.
