Extractor usage：How to get the result and return

[k3rwin]

Can the fields in the response packet be extracted and returned to the terminal scan result?
For example, if I want to get the execution result of the whoami command, how can I extract the result from the response packet and return it to the terminal scan result?

thanks！

@k3rwin, you can use extractors to print any or additional info in the CLI output, for example -

nuclei-templates/http/exposed-panels/ewm-manager-panel.yaml

Line 34 in 2447532

Another question, I just want to print out the regular matching group 1, is there a relevant syntax for this, such as r"xxx(.*)xxx"[1] in python

[k3rwin]

group: 1
thanks!

another question of extractors,how to use or to match multiple regular expressions, if the first one is matched, the second one will not be matched.
For example, linux use \n and windows use \r\n,I only want to match once,Is there any parameter setting? like condition: or in matchers

    extractors:
      - type: regex
        group: 1
        part: body
        regex:
          - '<string>(.*)\r\n</string>'
          - '<string>(.*)\n</string>'

Using this configuration can also achieve the effect, but I would like to ask how to use the built-in parameters to achieve the same effect

    extractors:
      - type: regex
        group: 1
        part: body
        regex:
          - '<string>(.*)\r\n</string>'
          - '<string>(.*\w)\n</string>'
