Run Verb

run provides the core functionality for dug and is used to query a large number of servers in parallel (or at least as parallel as you want).

run should be invoked as follows: dug run [<options>] domain or dug [<options>] domain (because run is the default verb)

Options#

OptionDescriptionDefaultPossible Values (if applicable)
-w, --watchRe-run the specified query and update the output table every X millisecondspositive integer
-f, --fileUse DNS servers in the specified list for this run. (Must be in default csv format (todo: page) or use --data-columns to specify csv structure)A filepath
-s, --serversThe servers to query against instead of the integrated servers.Any parseable IP (like 8.8.8.8), or multiple separated by commas (like 8.8.8.8,2001:4860:4860::8888)
--server-countdug runs queries against the top servers, ranked by reliability, per continent. This allows you to set how many servers from each continent to use.6integer >= 1
--continentsThe continents on which servers will be queried.AF,SA,NA,OC,AS,EU,ANAny of the following (or multiple separated by commas): AF, SA, NA, OC, AS, EU, AN
-q, --query-typesThe query type(s) to run against each server.AAny of the items in the Query Types table below (or multiple separated by commas)
-m, --multiple-sourcesWhen specifying servers (-s or --servers) also use integrated servers.false
--data-columnsSpecify the fields, and their order, in the file specified with (-f). Must be used with (-f).Any of the following (or multiple separated by commas): ipaddress, countrycode, city, dnssec, reliability, ignore
--data-headers-presentSpecifies whether or not headers are present in the file specified with (-f). Can only be used in conjuction with --data-columns
--data-separatorSpecifies the separator to be used when parsing servers from the file specified with (-f). Can only be used in conjuction with --data-columns.,Any character
--output-templateSpecify which data, and in what order, to put into out. Ignored if --output-format=TABLES.Any of the following (or multiple separated by commas): ipaddress, countrycode, city, dnssec, reliability, continentcode, countryname, countryflag, citycountryname, citycountrycontinentname, responsetime, recordtype, haserror, errormessage, errorcode, value
--output-formatSpecify the output format. For formats other than the default you must also specify a template (--output-template).TABLESTABLES, CSV, JSON
-d,--table-detailSpecify the level of detail to show when rendering tables. Ignored if output-format is set to anything other than its default (TABLES)11, 2
