Argument description

• --cacert <file> - tells curl to use the specified certificate file to verify the peer

• --capath <dir> - tells curl to use the specified certificate directory to verify the peer. Multiple paths can be provided by separating them with ":" (e.g. "path1:path2:path3"). The certificates must be in PEM format, and if curl is built against OpenSSL, the directory must have been processed using the c_rehash utility supplied with OpenSSL

• --cert-type <type> - tells curl what type the provided client certificate is using. PEM, DER, ENG and P12 are recognized types

• --dns-servers <IP1,IP2...> - allows us to list DNS servers curl should use instead of the system default

• -k --insecure - makes curl skip the verification step and proceed without checking

• -I --head - fetches the headers only

• -s --silent - don't show progress meter or error messages
