What does -sS option do?

The -sS option is used with the curl command. It combines two flags:

• -s: This flag stands for "silent" mode. It makes curl operate without showing progress or error messages. This is useful when you want to suppress output and only get the response data.

• -S: This flag is used in conjunction with -s. It tells curl to show an error message if it fails. So, if an error occurs while using silent mode, you will still see the error message.

In summary, using -sS with curl allows you to suppress normal output while still being informed of any errors that occur.
