dnstxt — look up the text records of a domain name
dnstxt looks up the TXT resource records for
fqdn in the Domain Name System, and prints them.
If there are no TXT resource records, dnstxt prints a blank line.
Normally dnstxt exits 0. If it encounters a temporary problem that prevents it from determining the MX resource records, it prints an error message and exits 111.
dnstxt makes all DNS lookups using the locally configured DNS proxy server. See dnsqr(1) for how this server is found.
