--trace-ascii

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 send the output to stderr.

This is similar to --trace, but leaves out the hex part and only shows the ASCII part of the dump. It makes smaller output that might be easier to read for untrained humans.

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.
