arguments:
  -h, --help            show this help message and exit
  -w wordlist           Directory wordlist
  -u target             Target URL/IP address ([scheme://]host[:port]).
                        Default port is 443 and HTTPS enabled. To specify
                        otherwise, use ':port' and/or 'http://' (port will
                        default to 80 then).
  -c connections=8      Number of HTTP/2 connections.
  -t threads=20         Number of threads per connection.
  -m http_method=HEAD   HTTP request method. Allowed values are GET, HEAD.
  -r directory_depth=2  Maximum recursive directory depth. Minimum is 1,
                        unlimited is 0.
  -hd header_list       List of headers in the format
                        'header->value|header->value...'. For example: -hd
                        'user-agent->Mozilla/5.0|accept-encoding->gzip,
                        deflate, br'.
  -x extension_list     List of file extensions to check separated by a
                        vertical bar (|). For example, -x '.php|.js|blank|/'.

  -b http_code_list     List of blacklisted response codes separated by a
                        vertical bar (|). Directories with these response
                        codes will not be shown in the output. Default is 404.
  -l                    Flag: show response length in output. This overrides
                        the request method to GET.
  -vr                   Flag: force TLS certificate verification.
  -wc                   Flag: request a random path and analyze response to
                        detect false positives (wildcard processing).
  -rb                   Flag: scan for a robots.txt file. If found, a prompt
