  -f, -filter string[]   subdomain or list of subdomain to filter (file or comma separated)

RATE-LIMIT:

  -rls value            maximum number of http requests to send per second for providers in key=value format (-rls "hackertarget=10/s,shodan=15/s")
  -t int                number of concurrent goroutines for resolving (-active only) (default 10)

UPDATE:
  -up, -update                 update subfinder to latest version
  -duc, -disable-update-check  disable automatic subfinder update check

  -o, -output string       file to write output to
  -oJ, -json               write output in JSONL(ines) format
  -oD, -output-dir string  directory to write output (-dL only)
  -cs, -collect-sources    include all sources in the output (-json only)
  -oI, -ip                 include host IP in output (-active only)

CONFIGURATION:
  -config string                flag config file (default "$CONFIG/subfinder/config.yaml")
  -pc, -provider-config string  provider config file (default "$CONFIG/subfinder/provider-config.yaml")
  -r string[]                   comma separated list of resolvers to use

OPTIMIZATION:
  -timeout int                  seconds to wait before timing out (default 30)
  -max-time int                 minutes to wait for enumeration results (default 10)
