--trace

Save a full trace dump of all incoming and outgoing data, including descriptive information, in the given output file. Use "-" as filename to have the output sent to stdout. Use "%" as filename to have the output sent to stderr.

Note that verbose output of curl activities and network traffic might contain sensitive data, including usernames, credentials or secret data content. Be aware and be careful when sharing trace logs with others.
