unbound - Unbound DNS validating resolver 1.4.22.

unbound [ -h ] [ -d ] [ -v ] [ -c cfgfile ]

Unbound is an implementation of a DNS resolver, that does caching and DNSSEC validation.

The available options are:

-h Show the version and commandline option help.

-c cfgfile Set the config file with settings for unbound to read instead of reading the file at the default location, /var/unbound/unbound.conf. The syntax is described in unbound.conf(5).

-d Debug flag, do not fork into the background, but stay attached to the console. This flag will also delay writing to the logfile until the thread-spawn time. So that most config and setup errors appear on stderr.

-v Increase verbosity. If given multiple times, more information is logged. This is in addition to the verbosity (if any) from the config file.
