curl:tldr:540ac

The given command is using the command-line tool curl to make an HTTPS request to example.com while specifying client certificate and key files for authentication.

Let's break down the command:

• curl: The command-line tool used for making HTTP/HTTPS requests.
• --cert ${client-pem}: Specifies the client certificate file to be used for authentication. The ${client-pem} is likely a placeholder that should be replaced with the actual filename or path of the client's PEM certificate file.
• --key ${key-pem}: Specifies the private key file associated with the client certificate. The ${key-pem} is again a placeholder that should be replaced with the actual filename or path of the private key PEM file.
• --insecure: This option tells curl not to verify SSL certificates. It allows insecure server connections and disables SSL certificate validation. It is often used during the development or testing phase but should not be used in a production environment.
• ${https:--example-com}: Indicates the URL of the HTTPS request. In this case, it is https://example.com. The ${https:--example-com} is used as a placeholder, and the example.com should be replaced with the actual URL.

To execute this command successfully, make sure to replace the placeholders ${client-pem}, ${key-pem}, and example.com with the appropriate values.
